What is an electromechanical time switch?
An electromechanical time switch is a device designed for control, through trippers, the switching on and off of electrical circuits in a domestic, or industrial, environment. Thanks to a built-in timer, it can automatically turn on and off the circuit to which it is connected, according to preset times. 

How it works 
The electromechanical time switch is very easy to use. It works thanks to the trippers, each corresponding to 30 minutes of maneuver, which combined determine the total duration of the maneuver. The front minute disc should be turned in the indicated direction to set the current time. As time runs out, it triggers counters based on how the trippers were placed. The electromechanical time switch with trippers has a rechargeable NiMH battery with a power reserve of 150 hours. The battery can be easily replaced when exhausted by accessing the flap on the front of the instrument. 

There are three possible modes of operation, selectable through the manual selector on the front of the switch:

  • 0 = always off
  • A = automatic 
  • I = always on 

How the product looks like
The device has the size of 2 DIN. On the front of the switch there is a 24-hour dial with 48 trippers, two hands and a small knob (switch) useful for setting the method of operation. At the top of the switch is a small drawer that allows battery replacement. 

Vemer also provides:
