OEX ACX3716BL 16A SPDT Momentary Rocker Switch 12/24V Heavy-Duty

OEX ACX3716BL 16A Three-Position Momentary On/Off/Momentary On SPDT Rocker Switch 12V and 24V Carling Format 21x37mm 3 Blade Terminals

The OEX ACX3716BL is a 16A three-position momentary On/Off/Momentary On SPDT rocker switch rated for 12V and 24V, with a 21x37mm Carling-format mounting hole and three blade terminals. Rocking the switch to either end activates the corresponding momentary contact, and the switch spring-returns to the centre Off position when released. Neither end latches the centre Off position is always the rest state. The three-position momentary SPDT configuration is suited to dual-direction control applications including electric window lifts, powered antenna up/down controls, sunroof open/close and other reversible motor or actuator circuits. Non-illuminated. Covered by a one year warranty.

Product overview

This switch is fundamentally different from a standard two-position On/Off rocker. A standard rocker latches in position pressing one end turns the circuit on and it stays on until pressed again. The ACX3716BL has three positions and neither end latches. Rocking to one end activates that momentary contact only while held; releasing the switch springs it back to the centre Off position automatically. Rocking to the other end activates the opposite contact, again only while held. The motor or actuator stops immediately when the switch is released.

This centre-off spring-return behaviour is the correct configuration for reversible motor control electric window motors, powered antenna motors, sunroof actuators and linear actuators where the motor must run only while the switch is actively held in a direction. The SPDT configuration provides three independent blade terminals: a common centre terminal plus one for each momentary contact position. At 16A across 12V and 24V it handles many motor control applications directly, but for high-current motors the switch terminals should trigger relays rather than carry motor current directly.

Features and benefits

Three-position Momentary On/Off/Momentary On: Rocks to either end for momentary activation. Spring-returns to centre Off when released. Neither end latches.

SPDT configuration centre Off rest position: Single pole double throw with independent connections for each direction. Centre Off ensures the motor or actuator stops immediately when released, preventing overrun.

Suited to reversible motor and actuator control: Electric window lifts, powered antenna up/down, sunroof open/close, linear actuators and other dual-direction control applications.

16A at 12V or 24V: Dual-voltage rating for passenger vehicle and commercial vehicle applications.

3 blade terminals: Common centre terminal plus one for each momentary contact position.

21x37mm Carling-format mounting hole: Standard panel size for marine, 4WD and aftermarket switch panels.

Non-illuminated: Straightforward operation without LED indicator.

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

Frequently asked questions

What does three-position momentary On/Off/Momentary On mean? This switch has three positions: Momentary On at one end, Off in the centre, and Momentary On at the other end. Rocking it to either end activates the corresponding contact only while the switch is held in that position. When released, the spring mechanism returns the switch to the centre Off position automatically. Unlike a standard rocker switch, neither end stays latched the switch always returns to centre.

What applications is this switch used for? The three-position momentary SPDT configuration is suited to controlling reversible motors and actuators electric windows, powered antennas, sunroofs and linear actuators where rocking one way runs forward and the other way runs in reverse, with the motor stopping automatically when the switch is released.

How does the SPDT configuration work for motor control? In a typical motor reversing application, the common terminal connects to the motor feed and each outer terminal connects to one polarity of the supply or to a relay coil. Rocking one way activates one direction; rocking the other way activates the reverse. Releasing the switch returns to centre Off, stopping the motor. For high-current motor applications, use the switch terminals to trigger relays rather than carrying motor current directly through the switch.

What panel cutout does this switch require? The switch requires a 21x37mm rectangular panel cutout the standard Carling-format size used in many marine and 4WD switch panels and aftermarket consoles.

What is the maximum current this switch can handle directly? This switch is rated at 16A at 12V or 24V. For motor circuits drawing more than 16A, use the switch terminals to trigger a relay or contactor rather than wiring the motor directly through the switch.
