This Lochinvar Rocker Switch is a type of electrical switch that rocks back and forth, hence the name. It features a Single Pole Single Throw (SPST) configuration, meaning it has one input and one output. The switch is designed to control the flow of electricity within a circuit, allowing for the operation of various electrical devices. It operates on an "on/off" mechanism, where one end of the switch turns the circuit on and the other end turns it off. The Lochinvar Rocker Switch is typically used in residential, commercial, and industrial settings due to its simple design and ease of use.
