Digital Time Switch EG103B/E

The digital time switch weekly cycle, EG103B / E, in a compact 2-module housing, offers excellent automatic control of electrical loads and energy management with easy-to-use manual programming or via an optional programming key or software.


Time switches are used to control electrical loads, such as public lightings, signage, water pumps, according to the desired day and/or time.

This improves comfort and saves energy as the load is only switched on at the particular day/time and automatically switches off according to the programme.

  • user friendly programming interface
  • long term (5 yrs) power reserve
