Reverse Polarity Switch - Momentary Operation

Control your 2-wire motorised valve actuator easily with this momentary ON-OFF-ON rocker switch. Designed for reversing polarity applications, this switch sends power one direction when pressed one way and reverses polarity when pressed the other way—perfect for OPEN / CLOSE valve operation.

Key Feature: Momentary Action

Unlike maintained switches, this model is momentary, meaning it returns to the centre OFF position automatically when released. This helps prevent accidental continuous operation and gives you push-and-hold control of the valve.

Perfect Fitment

This switch measures 25mm wide x 30mm tall and can be neatly fitted into a CBE blanking plate, making it ideal for caravans, motorhomes, campervans, boats, and custom control panels.

Ideal For:

• 2-wire electric ball valves
• Motorised shut-off valves
• Water control systems
• Irrigation systems
• HVAC zone valves
• Caravan & motorhome water systems
• Custom automation panels

How It Works:

• Press Up = Opens valve (or closes, depending on wiring)
• Release = Returns to centre OFF
• Press Down = Reverses direction
• Release = Returns to centre OFF

Specifications:

• Type: DPDT Rocker Switch
• Positions: Momentary ON-OFF-ON

Why Use a Momentary Switch?

A momentary switch is ideal for valve actuators because it only powers the motor while you hold the switch, reducing wear and avoiding leaving power applied after the valve reaches its stop.
