BIR Impulse Relay

BIR Impulse Relay


Closing of the impulse relay pole(s) is triggered by an impulse on the coil.

Having two stable mechanical positions, the pole(s) will be opened by the next impulse.

Each impulse received by the coil reverses the position of the pole(s).

Can be controlled by an unlimited number of pushbuttons.

Zero energy consumption.
