Sierra RK40830 Compact Marine Rocker Switch – Off-(On), SPST, Momentary, 12/24VDC, AC Rated
The Sierra RK40830 is a compact momentary rocker switch with an Off-(On) SPST configuration. The switch springs back to off the instant you release it — there is no maintained on position. This makes it the correct choice for any application where you want the circuit to energize only while actively pressing the switch: horn activation, alarm tests, starter triggers, bilge pump manual overrides, and similar momentary-contact functions.
The high-profile rocker action delivers a crisp, positive feel with every press, giving clear tactile confirmation that the switch has been activated. Its compact body fits a standard rectangular panel cutout. Rated for both AC and DC operation — 12A at 125V AC, 10A at 250V AC, and suitable for 12V and 24V DC systems.

Parts Desk Insights
The RK40830 is the right choice when you need a compact momentary switch — the circuit is only active while you’re pressing it, which is the correct behavior for horns, alarms, and manual override functions where you don’t want the circuit to stay on unattended. The high-profile rocker gives a more positive tactile feel than a flush push-button, which is useful when you need confident activation confirmation. If you need a maintained On-Off switch in the same compact series, the Sierra RK40800 Compact On-Off SPST is the latching alternative. For a momentary-both-sides compact switch with a center-off position, the Sierra RK40870 Compact (On)-Off-(On) SPDT covers dual-direction momentary applications.
