How are furnace switches wired?

Furnace switches are typically wired using a standard electrical method where a switch is connected to the furnace's power supply. The switch is usually installed in line with the power source, allowing it to interrupt the electrical flow to the furnace when turned off. This setup typically involves connecting the hot wire from the power supply to one terminal of the switch and a wire leading to the furnace to the other terminal. Additionally, a neutral wire may also be connected to complete the circuit, and grounding is essential for safety.
