BIR-32 Impulse Relay

BIR series pulse relay coils are triggered by pulses and their contacts close. The product has two stable mechanical positions and the contacts will open when the next pulse comes.

Each received pulse will invert the position of the contacts, controllable by an unlimited number of push buttons. And it has the characteristics of zero power consumption.

Pulse relays can be used to control lighting circuits through buttons. The circuit consists of incandescent lamps, halogen lamps, etc. (resistive load), fluorescent lamps, discharge lamps, etc.(inductive load).

Comply with standards: GB/T 21711.1, IEC60669-2-1
