Purchase advice on the timer comparison or test 2018

  • Timers help save power by powering connected devices only at the set time. This not only protects your wallet but is also good for the environment.
  • In principle, timers - just like normal wristwatches - can be divided into analog and digital timers.
  • Timers are used both indoors and outdoors. Depending on the intended use, you should pay attention to the designated protection class of the clock: A timer which is installed outside should at least have the protection class IP44 (protection against dust and splash water), while an indoor clock can do with a simple dust protection (IP20).

Wherever devices are to be switched on and off at regular intervals, a timer can make your everyday life easier. Whether for the Christmas lights in the garden or the light in the aquarium: The timer guarantees a punctual activation of the currentwithout you even having to think about it.

In which scenarios digital and analog timers can still be used and what you should pay attention to when buying, you will find in our timer comparison 2018. With the help of our purchase advice, you can quickly inform and thus find your personal timer test winner.

1. Precise (de) activation of devices thanks to a timer

Timer comparison 2018: comparison

No matter if a timer from Brennenstuhl or from Busch-Jäger: A timer switches the device connected to the clock on or off at pre-set times, The switching times are variably adjustable. Depending on the type of clock, for example, devices connected in the daily, weekly or annual rhythm can be controlled.

For this purpose, the timer is simply plugged into the socket and then the device to be controlled in the socket of the timer.This saves you the clock daily annoying switching on and off of equipment, Especially popular are timers in the outdoor area, because you do not have to leave the house extra to flip a switch.

Furthermore, timers are often used:

  • Aquariums, terrariums and ponds (for light and / or pump)
  • lamps
  • shutters
  • heaters
  • Outdoor lighting, which is unnecessary during the day (for example, lights in the garden)
  • WLAN router

In principle, a timer is always suitable if devices are to be put into operation on a time-dependent basis.

With a digital weekly timer, e.g. organize the activation of the aquarium lamp for the whole week.

Here the Advantages and disadvantages of timers at a glance:

  • reliably control the power supply of the connected device
  • help save electricity and electricity costs
  • flexible settings possible
  • can be used indoors and outdoors
  • analog timers only adjustable in 15 minute cycles
  • little intuitive handling of some digital timers
  • consume about one watt of electricity per hour

2. Timer types

The most common types used in the use of timepieces are explained in the following table:

Switches typeproperties
daily timer

Timer comparison 2018: comparison

  • Interval of 24 hours can be planned
  • Often built as a mechanical timer
  • Timer usually not battery operated

Timer comparison 2018: comparison

  • Interval of one week can be planned
  • Different programming of the weekdays possible
  • Often built as an electronic timer, equipped with display
  • often battery operated

Besides these two types, there are even more specific clocks. Although these are not quite as often in use and thus less common, but nevertheless no less practical:

  • yearly: With this electronic timer, every day of the year can be programmed differently. Thus, e.g. Special conditions are created for holidays, or if you go on holiday for two weeks during the summer. In particular, in the industry such time switches are used.
  • Timer comparison 2018: comparison

    Short-time switch
    : These timers are better known as "timers" or "countdowns". They are not based on the absolute time, but it is set a certain period of time after which then an action is triggered. Particularly inexpensive timers still use here a spring mechanism for initiating a process.

3. Digital vs. analogous

The difference between an analogue and digital time switch is not only noticeable during operation:

Switches typeMake the setting
Digital timer

accurate to the minute and complicated settings possible

easy to program via display and buttons

occasionally with random function to simulate presence on holiday

consumes more electricity than mechanical variant

requires batteries to save the settings

Unlike the analog version, there is no cog with teeth on a digital timer, but control is via an LCD display and buttons. Thus, an adjustment to the minute can be made and you are not tied to 15-minute bars, as with the analogue timer.

Timer comparison 2018: 2018

Analog timer

Timer comparison 2018: 2018

simple, fast operation

little power requirement

only adjustable in 15-minute slots

An analog, mechanical timer has a narrow wheel, which is equipped with many individual pins. These pens are assigned to precise 15-minute units. By pressing or pulling this out, the time can now be set. In the The time that the pins have been depressed will cause the power to turn on.

Because the integrated motor rotates the wheel into which the teeth have been inserted and the pins then directly actuate the contact so that power is applied.

In our example picture, the current would be from 19:15 to 22:30 and 06:00 to 09:30.

WLAN outlets can also have a timer integrated, Thus, you can home set the sockets from the phone via a timer and app.

Do you have Devices that should not be turned on and off at regular intervals, As an alternative, you can also use one Wireless socket think. This socket is activated by remote control and is therefore particularly recommended for sockets that you can not reach so easily because they are, for example, behind a closet.

4. What to look for when buying a timer

4.1. Select the type of timer according to the purpose

Priority should be given when buying a timer go after what you want to control with the clock, If you want to switch on the aquarium lamp every day at the same time, an analogue time of day clock is the right one.

Here we recommend choosing an analog timerbecause it can be adjusted very quickly and requires less power during operation than the digital version. But if the electric shutters at different times every morning to start up, offers here as a roller shutter timer rather a weekly timer.

Timer comparison 2018: 2018

Timer with protection class IP44.

Here, the individual timers with outlet can differ in the number of their switching segments - ie how many and how fine the settings can be, For mechanical watches, you will usually find 96 pins (4 x 24), ie switching segments, since the 24 hours can only be selected in quarter hours.

Digital timers have a wider range of functions: There you can often make 16 different settings for a day. Some manufacturers and brands advertise that their watches can store up to 140 settings per week. So you are maximally flexible.

4.3. mounting

The majority of the timers can not speak of a proper assembly, because the timers are simply plugged into the socket.

But e.g. For roller shutter timers so-called flush-mounted timers are often used because they can - similar to a light switch - can be integrated into the wall and not stand out unnecessarily. The Concealed timers should be placed in a flush-mounted box of at least 60 mm diameter. The installation of these timers is sometimes a little tricky, but the work is worthwhile if the clock is not supposed to attract attention.

protection classes

The name of the respective protection class consists of two digits. The higher these are, the better the product is protected against external influences such as dust or water. The first digit describes the protection against foreign bodies and touch, the second the protection against water.

Furthermore, there are also surface-mounted timers. These are fastened with screws to the wall and are therefore rather unpopular, as they leave traces when dismantling. Also in our timer comparison they are not listed.

4.4. protection

In principle, timers for domestic use have only two protection classes that the device can have: IP20 or IP44.

For example, flush-mounted timers of class IP20 are armed against foreign bodies with a diameter of 12.5 mm. At the same time these timers have oneParental control, which prevents the offspring without further access to the socket.

The best outdoor clock should be IP44 rated. These are constructed in such a way that foreign objects with a diameter of 1.0 mm and above are not protected, and they are additionally protected against splashing water from each side.

5. Questions and answers around the topic of time clock

5.1. What does Stiftung Warentest say about this topic?

Timer comparison 2018: timers

So far, the testing institute has not yet carried out a timer test, so that we can not present you with a timer test winner.

However, if you often organize your devices via power strips, you might be interested in the socket strip test from issue 07/2011. The conclusion: Internal protection and overvoltage protection are important purchase criteria, therefore convincing models of APC and Belkin. The price difference of both devices is about 3 euros.

5.2. How does a timer work?

An electronic timer works just like a regular digital clock or a clock radio: When a certain time has been reached, an action is carried out, With the clock radio, the radio starts and the timer switches a system on or off. Since there is a small PC-like processor installed, can be made to the minute settings and days of the week, for example, recognized.

Timer comparison 2018: timer

A Wi-Fi socket with timer can be easily adjusted by app.

The mechanical timer has an analog clock installed. The integrated motor moves the ratchet wheel according to the clock, so every quarter of an hour another pin is moved to the decisive position.

5.3. How much power does a timer consume?

As the clocks are connected to the mains throughout their lifetime, they too have a kind of standby power consumption. In principle, one can say that an analog timer consumes less power than a digital timerbecause with the digital variant, the LCD display must be supplied with power.

While analog clocks consume about one watt of power, the digital draws about two watts per hour from the outlet.

But as clock timer tests show: extrapolated to the year results so only a cost difference of about two euros on the electricity bill.

5.4. Are there waterproof timers?

Timer comparison 2018: timer

There is no fully watertight timer because the use of electricity in the water is much too dangerous. But irrigation computers are used in gardens. These are also timers, which have a water connection and can be switched between hose and faucet.

Furthermore, there are splash-proof timers, These are rated IP44 and have protective flaps so that rain does not get inside. Thus, these timers are suitable for the outside, for example, to regulate the Christmas lights in the garden.
