On-Off-On SPDT Heavy Duty Toggle with Screw Terminals. This SPDT switch latches in three positions: ON, center OFF, and ON. Rated 10A @ 277V AC, 20A @ 125V AC, 21A @ 14V DC (single pole); motor load 3/4 HP @ 125-250V AC (single pole).

Use it for: choosing between two loads or modes — high/low, two light sets, or selecting between two sources with a center OFF.

How it is wired: SPDT (single pole, double throw): one input routed to either of two outputs. Connect with ring terminals or spade terminals under the screws. Mounting hole: 1/2" (0.500"). Always check that the rating covers your load, and fuse the circuit to protect the wire.
