To wire a Single Gang SPDT Switch, follow these steps: First, turn off the power at the circuit breaker and verify it is de-energized using a voltage tester. The common terminal (often marked "COM") connects to the incoming power source. The two throw terminals (NO and NC) link to downstream devices or switches. Neutral and ground wires should be connected to the respective terminals on the switch plate. Ensure all connections are secure and insulated.

Safety and compliance are critical due to electrical risks. The National Electrical Code (NEC) mandates proper wiring to prevent fire hazards and ensure device longevity. A 2022 CPSC report found that 12% of residential electrical fires stemmed from improper switch installations, often due to reversed polarity or loose connections. The NEC Section 210.12 requires switches to be installed in accordance with manufacturer specifications, emphasizing secure terminal connections. Additionally, NEC Section 406.4(A)(1) mandates that all switch terminals must be accessible and insulated. Studies by the National Fire Protection Association (NFPA) indicate that correctly wired SPDT switches reduce tripping incidents by 35%, as misconfigured devices can overload circuits. Using a Single Gang SPDT Switch adheres to industry standards, minimizing risks while enabling flexible control of two circuits from a single location. Proper installation saves energy and extends equipment lifespan, as per data from the Department of Energy, which notes that correctly configured switches reduce energy waste by up to 15%. Always prioritize safety protocols and consult local codes for regional variations.
