A relay switch is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. Here you can get Battle Switch, XH-M131 Light Control Switch, SPDT Relay, Power Failure Relay and many more modules.

The switch may have any number of contacts in multiple contact forms, such as making contacts, break contacts. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal.
