Bistable relay BIS-402 BIS-402

Electronic bistable impulse relay allows you to switch on lighting or other device from several different points by means of control buttons connected in parallel. Operation:

The receiver is switched on after a current pulse caused by pressing any momentary (bell) button connected to the relay. The receiver will be switched off after the next impulse.

The relay does not have a "memory" of the contact position, i.e. in the event of a power failure and its return, the relay contact will be set to the off state. This makes it impossible to automatically switch on the controlled receivers without supervision after a long-term power failure. NOTE!

BIS-402 cannot work with illuminated switches.
