OEX ACX3677BL Push Button Switch Off Momentary On SPST (Contacts Rated 10A @ 12V)

Compact Momentary Push Button Switch for 12V Trigger and Accessory Applications

Product Overview

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. Like all momentary switches, the circuit is active only while the button is held down the internal spring returns it to the Off position as soon as it is released. This makes it suited to applications that require a brief trigger pulse: horns, engine start buttons, relay trigger circuits, door releases, and other momentary accessory activations.

Compared to the ACX3609BL (22mm mount, 20A), the ACX3677BL uses a smaller 12mm panel hole the same standard mount diameter as the OEX rocker and push/pull switch range making it a clean, consistent fit in panels that already use 12mm round hole switches. At 10A and a lighter 0.02kg, it is a compact, lightweight option for lower-current momentary switching in dash, console, and panel installations. Two terminals provide direct wire connection.

Features & Benefits

• Momentary On action — circuit is active only while the button is depressed; spring return automatically restores Off when released
• 10A at 12V — suited to horn circuits, relay trigger signals, dome light switches, and general momentary accessory activation
• 12mm mounting diameter — standard 12mm round hole; consistent with OEX rocker and push/pull switch range for uniform panel appearance
• 6mm mount length — suits standard panel thicknesses without requiring excessive panel depth
• 2 terminals — direct wire connection for the switched circuit
• Non-illuminated — straightforward momentary operation without LED indicator
• Compact and lightweight — 0.02kg for minimal dash and console impact

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 rest (Off) position and the circuit opens again. This is different 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 this differ from the ACX3609BL?

Both are Off/Momentary On SPST push button switches, but 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. Choose the ACX3677BL for a consistent panel appearance with other 12mm OEX switches; choose the ACX3609BL for a larger 22mm installation or 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 your panel thickness does not exceed the mount length before installation.

Can this switch directly drive a high-current load?

At 10A, this switch can handle 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 such as the OEX ACX3322 rather than wiring the load directly through the switch contacts.

Is this switch waterproof?

Water resistance or IP rating is not specified for this SKU. For installations in exposed or wet environments, consider the ACX3609BL (described as water resistant) or confirm suitable weatherproofing with OEX before installing in an outdoor location.
