The PBM-03 bistable relay is used to control lighting or any other device by means of parallel connected single-pole pushbuttons. Successive pressing of any of the buttons causes switching on or off the devices connected to the output terminals. The control impulse can be a signal from the L or N line. After giving the impulse, which will switch on the receiver, and then wait for the set time t, the receiver is automatically switched off.
