DPST Boat Rocker Switch 20A/125V 22A/250V

A boat rocker switch gets its name from the sealed, tactile toggle design originally developed for marine use, and that same ruggedness makes it a popular choice for automotive and appliance panels well beyond boats specifically. Unlike a small signal-level tactile switch, this is a genuine power switch - DPST (double pole, single throw) construction switches two independent circuits simultaneously with one rocker action, and its 4-terminal layout supports that dual-circuit switching directly.

Rated current varies meaningfully by load type, which matters for correctly sizing it to an application: 20A/125V or 22A/250V for simple resistive loads, but considerably less (down to roughly 4-8A) for inductive, motor, lamp, or capacitive loads specifically, since those load types stress a switch's contacts harder during the brief current surge at turn-on. An illuminated red lamp option gives visible on/off status at a glance on a control panel.

Common uses are automotive and marine accessory power switches, appliance and equipment on/off panel controls needing genuine current capacity, and DIY power tool or workshop equipment control panels wanting a rugged, panel-mount switch rather than a small PCB-level component.
