OEX ACX3609BL Push Button Switch Off Momentary On SPST (Contacts Rated 20A @ 12V)

OEX ACX3609BL 20A Momentary Push Button Switch Off/Momentary On SPST 12V 22mm Mount Water Resistant Bronze Contacts

The OEX ACX3609BL is a 20A momentary push button switch in an Off/Momentary On SPST configuration, rated at 12V with a 22mm mounting stem. Unlike a latching switch that stays in position when pressed, a momentary switch is only active while the button is depressed the spring return mechanism automatically restores the Off position the moment it is released. Suited to horn circuits, starter buttons, door release solenoids, relay trigger circuits and momentary accessory activations. Water resistant, bronze contacts, two screw terminals. Fits panels up to 6.35mm thick. Covered by a one year warranty.

Product overview

A momentary switch produces a brief trigger pulse rather than a sustained on/off state the circuit closes when the button is pressed and opens the instant it is released. This makes the ACX3609BL the correct choice for any application requiring a momentary signal: vehicle horns, engine start buttons, door and gate release solenoids, relay and solenoid coil triggers and light flash circuits. At 20A it can directly switch many loads as well as trigger relay coils for higher-current applications.

The 22mm metric thread mounting stem fits panels up to 6.35mm thick with a 22mm diameter hole. The water resistant construction suits outdoor, underbonnet and exposed mounting positions. Bronze contacts provide reliable electrical performance across repeated momentary switching cycles. Two screw terminals allow direct wire connection without crimped connectors. The compact form factor and standard 22mm mount are compatible with a wide range of aftermarket switch panels, consoles and custom fabricated mountings.

Features and benefits

Momentary On action: Circuit is active only while the button is depressed. Spring return automatically restores Off when released. Not a latching switch.

20A at 12V: Sufficient for direct switching of horns, solenoid coils, relay trigger circuits and moderate accessory loads. Use with a relay for loads exceeding 20A.

Water resistant: Suited to outdoor, underbonnet and exposed mounting positions.

Bronze contacts: Reliable contact material for repeated momentary switching cycles.

2 screw terminals: Direct wire connection without requiring crimped terminals.

22mm mounting stem with metric thread: Standard panel mount diameter. Fits panels up to 6.35mm thick. Requires 22mm diameter hole.

Non-illuminated: Straightforward operation without LED indicator.

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

Frequently asked questions

What is a momentary switch? A momentary switch is only active while it is being physically held in the pressed position. When released, the internal spring returns the button to the Off position and the circuit opens. This differs from a latching switch, which stays in the On position after being pressed. Momentary switches are used wherever a brief trigger pulse is needed rather than a sustained on/off state.

What applications is this switch suited to? The ACX3609BL suits any application requiring a momentary trigger: vehicle horns, engine start buttons, door and gate release solenoids, relay trigger circuits, light flash triggers and momentary accessory activation. At 20A it can directly switch many loads as well as trigger relay coils for higher-current applications.

What panel thickness does this switch suit? The 22mm metric thread mounting stem is 6.95mm long, fitting panels up to 6.35mm thick. For thicker panels, confirm the stem length is sufficient before purchasing.

Can this switch be used for high-current switching? At 20A this switch handles moderate loads directly. For loads exceeding 20A, use the switch as a trigger for a relay or solenoid such as the OEX ACX3322 rather than wiring the main load directly through the switch contacts.

Is this switch waterproof or water resistant? The ACX3609BL is water resistant, providing protection against splashing and moisture exposure but not full submersion. For applications requiring a specified IP rating such as IP65 or IP67, a switch with a confirmed weatherproofing rating should be selected.
