Sierra RK19500K Illuminated Rocker Switch, Off-On SPST with Dependent Pilot Light

The Sierra RK19500K is an illuminated, weather resistant rocker switch built for marine electrical panels. It is configured as an Off-On SPST switch with a dependent pilot light, meaning the light illuminates whenever the switch itself is in the "on" position, giving the operator an immediate visual confirmation that the circuit is live. The switch is a panel mount rocker design and carries an IP54 ingress protection rating, helping it resist splashing water, spray, and the humid conditions typical of a boat helm or accessory panel.

The switch comes with four snap-in lenses, one of each color, so it can be finished to match panel color coding or to visually distinguish circuits (for example, bilge pump, navigation lights, or accessory power) at a glance. The rocker actuator and housing are finished in white. Because the RK19500K uses a dependent pilot light rather than an independent one, it is best suited for installations where the operator wants the light tied directly to the switch state rather than to a separate panel illumination circuit.

How many lens colors come with this switch? Four snap-in lenses are included with the RK19500K, one of each color, so the switch can be color-coded for its circuit.

Is the RK19500K rated for wet or splash-prone locations? Yes, the RK19500K carries an IP54 ingress protection rating, which covers protection against dust and splashing water from any direction.

What color is the switch housing? The Sierra RK19500K rocker switch has a white housing and actuator.

How is the RK19500K installed? The RK19500K is a panel mount rocker switch, designed to snap into a standard rocker switch cutout on an electrical panel.

What is the difference between the RK19500K and the RK19510K? The RK19500K has a dependent pilot light that illuminates only when the switch is turned on, while the RK19510K has an independent pilot light that illuminates whenever the panel lighting is turned on, regardless of the switch position.
