Sea-Dog 420102-1 SPST Momentary On/Off Toggle Switch, 15 Amp 12 Volt, Brass/Nylon/Polycarbonate

The Sea-Dog 420102-1 is a water resistant SPST momentary on/off toggle switch built for marine electrical panels. It uses a locking ring with a lever seal and a protruding cap nut for a secure, water resistant panel mount, and is constructed of stamped brass, injection molded nylon, and polycarbonate for corrosion resistance in a marine environment. The switch is rated 15 Amps at 12 Volts DC and terminates in 2 spade blade terminals for simple wiring to bilge pumps, horns, winches, and other momentary-duty accessories where the circuit needs to stay on only while the switch is held. Its compact panel footprint (3/8 inch by 1/2 inch) makes it easy to fit into existing helm and console layouts alongside other Sea-Dog toggle switches. A matching waterproof cap is available separately for additional protection when the switch is not in use. This is a single switch, sold each, and is part of the same Sea-Dog toggle switch family that also includes standard on/off, DPDT, and illuminated variants sharing the same mounting dimensions and terminal style.
