How do you remove the electric wire off the switch on a oil pump switch?

To remove the electric wire from an oil pump switch, first ensure the power is turned off at the circuit breaker to avoid any electrical hazards. Use a screwdriver to loosen the terminal screw holding the wire in place, or if it's a push-in connection, press the release tab while gently pulling the wire out. Make sure to handle the wires carefully and avoid touching any exposed metal. If you're unsure, it's best to consult a professional electrician.
