Marine SPST LED Rocker Switch

The Marine Sport Lighting MSTLS04B is a single-pole, single-throw rocker switch designed for off-road vehicles, trucks, ATVs, UTVs and boats. It provides simple on/off control for auxiliary lighting circuits. The switch fits industry standard panel cutouts and includes a rubber gasket for a secure, weather-resistant installation. Two independently powered LED indicators give clear visual feedback of the switch state.

Blue LED indicators under continuous use

The blue LEDs are powered independently from the switched circuit, so they remain visible whenever the vehicle electrical system is live. This allows the operator to locate the switch in darkness without relying on the load being active. The SPST mechanism maintains a stable connection during prolonged operation, and the gasket helps protect internal contacts from moisture and vibration common in marine and off-road environments.

Industry standard panel cutout constraint

Installation requires a panel opening that matches the industry standard cutout dimensions for this switch format. The supplied rubber gasket seals the cutout against water ingress but does not adapt the switch to non-standard hole sizes. Builders using custom dash panels must verify the cutout matches the switch body before mounting. The switch is intended for low-voltage DC systems typical in automotive and marine applications.

Questions about this item

How much heat does the blue LED indicator produce when the switch runs all day on my boat?

The single LED indicator draws minimal current, so heat output stays negligible during continuous operation.

What wiring and circuit protection do I need to install this SPST rocker switch?

You need two power wires for the switch circuit, two separate leads for the independently powered LED indicators, and a fused supply matching your vehicle voltage.

Will this switch fit the existing panel cutout on my older off-road dash?

It installs in industry-standard panel cutouts and includes a rubber gasket for sealing.
