12V Push Button Switch ON-(ON) - Override Switch | 22MM, 2NO/2NC, IP67 Waterproof
Product: Override Switch • Momentary Push Button • Dual Circuit Control • Marine Override Button • 2NO/2NC Switch
Available Configuration
- 2NO/2NC Momentary Override: Two normally closed circuits (always active) and two normally open circuits (activate when pressed)
The 22mm ON-(ON) momentary push button switch is the ultimate solution for dual-circuit override applications where you need precise control. This IP67 waterproof switch features a 2NO/2NC configuration, making it ideal for managing two systems with a single press, such as a marine bilge pump with manual override or an industrial conveyor's auto/jog function. Perfect for situations where you need automatic operation with the ability to manually override when necessary.
This momentary override switch provides unique dual-circuit functionality that makes it perfect for override applications:
- Normally Closed (NC) circuits remain active: Continuous operation of primary systems (ideal for automatic bilge pump via float switch)
- Normally Open (NO) circuits activate when pressed: Manual override or secondary function activation (perfect for forcing bilge pump ON regardless of float switch)
The integrated yellow LED indicator provides clear visual feedback when the override function is active, ensuring instant status recognition in demanding marine and industrial environments.

- 50,000+ cycle life – Long-lasting reliability for demanding applications
🛠️ How to Use this Momentary Override Switch
This 2NO/2NC momentary override switch is specifically designed for automatic systems that require manual override capability. The switch provides failsafe operation where primary systems continue running until you need to manually intervene.
🔹 Switch Functionality (2NO/2NC Contacts)
- At Rest Position: Two Normally Closed (NC) circuits are active, and two Normally Open (NO) circuits are inactive
- When Pressed: The two NC circuits deactivate, while the two NO circuits become active
This unique behavior makes it perfect for override logic where a primary system (connected to NC) is active, and a secondary override function (connected to NO) is triggered on demand.

⚡ Override Switch Wiring Guide
This 2NO/2NC override switch provides flexible wiring options for automatic systems with manual override capability. The pre-wired 5A leads make installation quick and safe.
🔹 Common Override Wiring Examples
| Override Application | NC Circuit (Always Active) | NO Circuit (Override Active) |
|---|---|---|
| Bilge Pump Override | Automatic float switch control | Manual override to force pump |
| Safety Interlock | Normal safety mode | Temporary bypass during servicing |
| Conveyor Jog | Auto conveyor run | Jog manually during alignment |
| Lighting Override | Standard lighting | Emergency flash or beacon |
| Windlass Safety | Locked in auto mode | Manual anchor control |
💡 Advanced Override Configurations
- Marine Bilge System: Float switch on NC | Manual override on NO
- Safety Interlock: NC holds safety; NO bypasses if needed
- Conveyor Jog: NC = auto, NO = jog/manual precision
- Backup System: NC = primary system; NO = activate secondary on demand
