The working principle of this switch is similar to an electric switch. This switch includes two contact points and the wires of this switch are simply connected to the circuit in a device.
When Normally Open (NO) contacts within the switch are not getting connected, then the circuit in the device is not connected, so the device will be turned OFF. Once this footswitch is compressed then two contacts will be closed so the electric circuit will be connected and the machine will be turned ON.
When Normally Closed (NC) contacts within the switch are closed, then the circuit in the device is connected until the switch is compressed so it breaks the circuit & the machine will be turned OFF.
