An Impulse Relay is a switching device used to control lighting circuits from multiple locations. While enabling users to control connected lighting systems via push buttons (momentary switches), it provides cost-effective and simple solutions for illuminating large spaces. Thanks to its special internal switching mechanism, pressing a push button once toggles the lighting circuit from ON to OFF if it is open, or from OFF to ON if it is closed. This switching function can be conveniently performed from multiple points using push buttons.
