Scope of application

Pulse relay coils are triggered by pulses and their contacts are closed
There are two stable mechanical positions and the contacts will open temporarily on the next pulse. Each received pulse will reverse the position of the contact and can be controlled by an unlimited number of buttons
Zero power consumption

The pulse circuit can be used to control the lighting circuit through the button, and its circuit composition is
Incandescent lamps, halogen lamps, etc. (resistive load)
Fluorescent lamps, discharge lamps, etc. (inductive loads)
Meet the standard: EN60669-2-2
