Momentary Control with Built-In Weather Protection
The Cole Hersee M608BP is a Single Pole, Single Throw (SPST) momentary push-button switch designed for marine and outdoor installations where moisture protection is non-negotiable. Press the button to close the circuit — release it and the spring snaps it back to off. The plasticized body is sealed against moisture and dirt, and the included black rubber button cover snaps over the face nut to add an extra layer of protection against spray and accidental activation.
Pre-wired with two 18-gauge insulated leads — each 12" long — this switch is ready to connect straight out of the box. The 5/8"-32 threaded stem fits standard marine panel cutouts and accommodates panels up to 1/2" thick.

Parts Desk Insights
Best use case: The M608BP is the right call when you need a sealed, pre-wired momentary switch that can be installed quickly in a wet or exposed location — the rubber button cover is a meaningful upgrade over bare push-button switches in spray-prone positions like bow rails, cockpit panels, or engine compartment horn triggers. The 12" leads eliminate the need for terminal hardware in most installations, and the sealed body holds up where open-terminal switches corrode and fail.

For a sealed push-pull On/Off switch with pre-wired leads, the Cole Hersee M606BP Push-Pull Switch is a close companion. Need a higher-amperage momentary option? The Cole Hersee 90030BP Heavy-Duty Push-Button Switch (35A) handles heavier loads.
