Siemens Control Relays LZS:RT17040

Siemens Control Relays LZS:RT17040 is an electrical switch. Control buttons or lamp buttons used in our homes are manually controlled. In other words, they need an external force to open and close. Relays, like buttons and light switches, turn a circuit on and off. The two most basic reasons for using a relay instead of a mechanical switch such as a lamp switch or control button for the opening and closing of an electrical circuit are that the relay can be remotely controlled and automatic control can be made with a relay.
