Sea-Dog 420429-1 Momentary Push Button Horn Switch, Chrome Plated Brass, 12 Volt

The Sea-Dog 420429-1 is a momentary push button horn switch built from chrome plated brass for long-lasting corrosion resistance in marine environments. It is used for operating fog horns, sirens, and similar signaling devices, activating the equipment in emergency situations or for communication with locks and bridges. As a momentary switch, it completes the circuit only while the button is pressed, returning to the off position as soon as it is released.

Rated for 12 Amps at 12 Volts DC, this switch is sized for typical 12-volt marine electrical systems. The faceplate measures 2-9/16 inches across, with an overall diameter of 1-5/8 inches, making it compact enough for helm panels, consoles, and other mounting locations where space is limited. It surface mounts using two #10 RH fasteners, which are not included and must be sourced separately.

Sea-Dog builds this horn switch to withstand the marine environment, using chrome plated brass to resist the corrosive effects of saltwater exposure. Its compact size and simple momentary operation make it a straightforward way for boat owners to trigger a horn, siren, or similar alert system from the helm.
