Impulse relays, also known as Bistable Switches, are a form of latch relays, used to switch various electrical loads. When the switch is not initiated electrically or actuated manually, it remains stable in its operating position and will change its operating position on initiation or actuation. Such as a lighting circuit, or a conveyor.
The impulse relays are used to control, by means of pushbuttons, lighting circuits consisting of:
Incandescent lamps, low-voltage halogen lamps, etc. (Resistive loads)
Fluorescent lamps, discharge lamps, etc. (Inductive loads)
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.
