ページ印刷Switch Definition
A switch responds to an external force to mechanically change an electric signal. Switches are used to turn electric circuits ON and OFF and to switch electric circuits.
1. Circuit ON/OFF Operation
The contacts are separated while the switch is not pressed, so the circuit is not connected and the lamp is not lit.
When the switch is pressed, the contacts come into contact, closing the circuit and lighting the lamp.
2. Circuit Switching Operation
While the switch is not operated, the lamp on circuit L1 is lit.
When the switch is pressed, the circuit is switched so that the lamp on circuit L2 is lit.
