Switch Units are woriking on basis of a bistable relay allowing very high capacities combined with a very low own consumption. They suitsespecially as a remote-controlled main switch or load relay which is on long-term power. The current carrying capacity conducts 40 A or 100 A.

Switch Units can be mote-controlled by a normal switch (1 pol. ON / OFF).

Furthermore the consumer can be switched on and off through an emergency switch at the relay by hand.

The ranges of application are campers, intervention vehicles and boats:

  • Easy selection through ON / OFF switch
