OEX ACX1967BL Push Button Switch Off Momentary On SPST

OEX ACX1967BL 50A Momentary Push Button Switch 12V and 24V SPST 16mm Panel Mount Waterproof Rubber Boot

The OEX ACX1967BL is a non-illuminated momentary push button switch rated at 50A, designed for 12V and 24V automotive, 4WD, caravan and commercial vehicle applications. When pressed it completes a circuit momentarily and returns to open when released, making it ideal for triggering horns, solenoids, air lockers, compressors and other momentary-action accessories. SPST configuration with two terminals, 16mm mounting hole and a waterproof rubber boot included. Covered by a one year warranty.

Product overview

A momentary switch completes the circuit only while the button is held down and returns to the open state when released unlike a toggle or rocker switch which latches in the on position. This behaviour is required for horns, solenoids, air locker triggers, compressor activation circuits, starter circuit override points and CB/UHF radio PTT wiring where a brief, controlled pulse of current is needed rather than a sustained connection.

At 50A the ACX1967BL handles high-draw momentary loads without overheating or voltage drop. The dual 12V and 24V voltage rating covers both light vehicles and heavy commercial vehicles including trucks, buses and 24V caravan and auxiliary setups. The waterproof rubber boot protects the switch body from moisture, dust and mud ingress for underbonnet, exterior panel and exposed dash installations. The 16mm mounting hole suits the majority of standard aftermarket switch panels, dash inserts and auxiliary control enclosures without custom modification.

Features and benefits

50A current rating: Handles high-draw momentary loads including solenoids, horns, air lockers and starter circuit override points without overheating or voltage drop.

Momentary On action: Circuit closes only while the button is held down and returns to open when released. Not suited to sustained-load or latching applications.

12V and 24V dual-voltage rated: Compatible with light vehicles and heavy commercial vehicles including trucks, buses and 24V caravan and off-road setups.

Waterproof rubber boot included: Protects the switch body from moisture, dust and mud ingress for underbonnet, exterior panel and exposed dash installations.

16mm mounting hole: A widely used panel cutout size that suits most standard aftermarket switch panels, dash inserts and auxiliary control enclosures without custom drilling.

SPST configuration 2 terminals: Simple single-circuit design with one input and one output. Connect the power feed to one terminal and the load to the other.

Non-illuminated: No LED illumination compact and low-profile for integration into tight spaces.

One year warranty: Covered by a one year OEX warranty.

Technical specs

Frequently asked questions

What is a momentary switch and how does it differ from a standard toggle? A momentary switch only completes the circuit while the button is held down and returns to the open state when released. A standard toggle or rocker switch latches in the on position until manually switched off. The ACX1967BL is momentary only and will not hold the circuit open when released.

Will this switch work on both 12V and 24V systems? Yes. The ACX1967BL is dual-voltage rated at 12V and 24V, making it compatible with light vehicles, heavy-duty trucks, buses and 24V caravan and auxiliary setups.

What size hole do I need to mount this switch? A 16mm diameter panel cutout is required. This is a common size in aftermarket switch panels, dash inserts and auxiliary control enclosures and should not require custom drilling in most setups.

Is this switch weatherproof? Yes. The switch includes a waterproof rubber boot that provides moisture and dust protection, making it suitable for underbonnet, exterior panel and exposed dash installations.

What does SPST mean and how do I wire this switch? SPST stands for Single Pole Single Throw one input terminal and one output terminal. Connect the power feed to one terminal and the load (horn, solenoid, relay or other accessory) to the other. No complex wiring is required.
