In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
An embedded flashing-light system, or an in-pavement flashing-light system, is a traffic safety device installed at pedestrian crossings or intersections to enhance driver awareness of pedestrians or traffic signals.

It acts as an electronic toggle switch, the half bridge is not able to switch polarity of the voltage applied to the load. The half bridge is used in some switched-mode power supplies that use synchronous rectifiers and in switching amplifiers. The half-H bridge type is commonly abbreviated to "Half-H" to distinguish it from full ("Full-H") H ...
