Description
OEX ACX3677BL 10A Momentary Push Button Switch Off/Momentary On SPST 12V 12mm Mount Non-Illuminated
The OEX ACX3677BL is a 10A momentary push button switch in an Off/Momentary On SPST configuration, rated at 12V with a 12mm mounting diameter. The circuit is active only while the button is held down the internal spring returns it to the Off position the moment it is released. Suited to horn circuits, engine start buttons, relay trigger circuits, door releases and other momentary accessory activations. The 12mm mounting diameter matches the standard OEX rocker and push/pull switch range for a uniform panel appearance. Two terminals for direct wire connection. 6mm mount length. Non-illuminated. Covered by a one year warranty.
Product overview
The ACX3677BL is a compact, lightweight momentary switch suited to dash, console and panel installations where a 12mm round hole is already in use for other OEX switches. Compared to the ACX3609BL (22mm mount, 20A, water resistant), the ACX3677BL uses the smaller 12mm mount diameter consistent with the OEX ACX1971BL, ACX1973BL and ACX3666BL switch range making it a clean, consistent fit in panels that already use 12mm round hole switches. The 10A rating handles horn circuits, dome lights, relay and solenoid coil triggers and general low-to-moderate current momentary applications directly. For loads exceeding 10A, the switch should trigger a relay or solenoid rather than wiring the load directly through the switch contacts.
A momentary switch differs from a latching switch in that it cannot hold the circuit open on its own pressing and releasing it produces a brief pulse, not a sustained on/off state. This is the correct behaviour for horns, start buttons and relay triggers where only a momentary signal is needed.
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.
10A at 12V: Suited to horn circuits, relay trigger signals, dome light switches and general momentary accessory activation.
12mm mounting diameter: Consistent with the standard OEX rocker and push/pull switch range (ACX1971BL, ACX1973BL, ACX3666BL) for a uniform panel appearance.
6mm mount length: Suits standard panel thicknesses in most dash and console applications.
2 terminals: Direct wire connection for the switched circuit.
Non-illuminated: Straightforward momentary operation without LED indicator.
Compact at 0.02kg: Minimal dash and console impact.
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 that 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, such as horns, start buttons and relay triggers.
How does the ACX3677BL differ from the ACX3609BL? Both are Off/Momentary On SPST push button switches. The ACX3609BL uses a 22mm mount diameter and is rated at 20A with a water resistant housing. The ACX3677BL uses a 12mm mount diameter matching the standard OEX rocker and push/pull switch range, and is rated at 10A. Select the ACX3677BL for a consistent panel appearance with other 12mm OEX switches, and the ACX3609BL for a larger 22mm installation or a higher 20A current requirement.
What panel thickness does this switch suit? The 6mm mount length suits standard panel thicknesses in most dash and console applications. Confirm the panel thickness does not exceed the mount length before installation.
Can this switch directly drive a high-current load? At 10A this switch handles low to moderate loads directly. For loads exceeding 10A such as main lighting circuits, compressors or winch enable circuits use the switch as a trigger for a relay or solenoid rather than wiring the load directly through the switch contacts.
Is this switch waterproof? Water resistance or an IP rating is not confirmed for this SKU. For installations in exposed or wet environments, consider the ACX3609BL (described as water resistant) or a switch with a specified IP rating.
