Key Switch Wiring Steps

Step 1 First determine the live wire and the neutral wire, both of which carry different voltages and currents.

Step 2 Connect the live wire of the power cord to the normally closed contact of the key switch, and in the same way, connect the neutral wire of the power cord to the negative pole of the switch, so that the first closure can be formed.

Step 3 Power-on test, press the button on whether it can turn on the electrical appliance, and whether pressing the off button can turn off the electrical appliance.
