OEX ACX3882BL | Toggle Switch | On/Off/On DPDT (Contacts Rated 25A @ 12V)

Three-Position DPDT Toggle Switch for Dual-Circuit and Reversing Applications

Product Overview

The OEX ACX3882BL is a 25A three-position On/Off/On DPDT (Double Pole Double Throw) toggle switch rated at 12V, with six blade terminals and a 12mm mounting diameter. The DPDT configuration switches two independent poles simultaneously each pole has its own common, and each can be directed to one of two outputs depending on the switch position. With three positions (On, Off, On), the switch provides two distinct active states plus a centre Off, making it well suited to polarity-reversing circuits, source-selection applications, and dual-circuit control where two separate circuits need to be managed from a single switch.

Toggle switches provide a distinctive tactile operation the lever flips between positions and holds, giving clear physical feedback of the selected state. At 25A and 12V, this switch has the current capacity for direct accessory switching as well as relay trigger applications. The 12mm mounting diameter suits the same standard round panel holes used by the OEX rocker and push button switch range. Six blade terminals accommodate the full DPDT wiring: two commons, two position-one outputs, and two position-two outputs.

Features & Benefits

• DPDT On/Off/On configuration — switches two independent poles simultaneously; three positions give two active states plus a centre Off
• 25A at 12V — high current capacity for direct switching or relay triggering in demanding accessory circuits
• 6 blade terminals — full DPDT wiring; two common terminals plus two outputs for each switch position
• Toggle lever action — flips between positions and holds; clear physical feedback of selected state
• Non-illuminated — clean, functional switch without LED indicator
• 12mm mounting diameter — standard round hole compatible with OEX rocker and push button switch range
• 3mm mount length — compact panel depth requirement

Frequently Asked Questions

What does DPDT mean?

DPDT stands for Double Pole Double Throw. It means the switch simultaneously controls two independent switching poles (circuits), each of which can be thrown to one of two output positions. In a DPDT switch, there are two commons — one for each pole — and two sets of output terminals. When the switch is moved to either On position, both poles simultaneously connect to their corresponding outputs for that position.

What are the three positions on this switch?

The three positions are On (position 1), Off (centre), and On (position 2). In position 1, both poles connect to their position-1 outputs. In the centre Off, both poles are disconnected. In position 2, both poles connect to their position-2 outputs. The switch holds in all three positions — it does not spring-return to centre.

What applications is a three-position DPDT switch suited to?

This configuration is commonly used for polarity reversing circuits — where one On position sends current in one direction through a motor or actuator, and the other On position reverses polarity to run in the opposite direction. It is also used for selecting between two power sources or two output circuits from a single switch, and for applications requiring both poles to be managed together.

How does a toggle switch differ from a rocker switch?

A rocker switch has a flat rectangular body that rocks side to side — the end you press down is the active side. A toggle switch has a lever that flips between positions. Both can have the same electrical configurations (SPST, DPDT, etc.), but the toggle lever gives a distinctive look and clear tactile feedback of which position is selected. Toggle switches are commonly associated with aviation, industrial, and custom vehicle panel aesthetics.

What mounting hole does this switch require?

The ACX3882BL requires a 12mm round mounting hole with a 3mm mount length — the same standard 12mm hole used by OEX rocker and push button switches in this range.
