OEX ACX3705BL Rocker Switch On/Off SPST (Contacts Rated 16A @ 12 or 24V)

OEX ACX3705BL 16A Non-Illuminated On/Off SPST Rocker Switch 12V and 24V Carling Format 21x37mm 2 Blade Terminals

The OEX ACX3705BL is a 16A non-illuminated On/Off SPST rocker switch rated for 12V and 24V systems, with a 21x37mm rectangular mounting footprint. The 21x37mm mount is the standard Carling-format panel size used widely in marine switch panels, 4WD accessory consoles and aftermarket switch housings the same footprint as the OEX ACX1975BL illuminated Carling style rocker. The ACX3705BL offers a non-illuminated option in the same format for installations where LED indication is not required or where a uniform non-lit panel appearance is preferred. Two blade terminals for direct wiring. 34mm mount length. Covered by a one year warranty.

Product overview

The ACX3705BL fills the non-illuminated position in the OEX Carling-format rocker switch range. Where the ACX1975BL (20A, blue LED) is the illuminated Carling-format option, the ACX3705BL provides the same 21x37mm format without illumination suited to panels where a clean, uniform appearance is preferred over lit indicators, or where the 24V rating is required alongside 12V compatibility in a Carling-format switch.

At 16A across both 12V and 24V systems, the ACX3705BL suits a broad range of accessory switching applications in passenger vehicles, 4WDs, caravans and commercial vehicles without needing separate part numbers for each voltage. The two blade terminals provide a direct two-wire connection. For loads exceeding 16A, the switch should trigger a relay rather than wiring the load directly through the switch contacts.

Frequently asked questions

What is a Carling-style mounting footprint? Carling style refers to a rocker switch format with a 21x37mm rectangular mounting footprint, widely used in marine and 4WD switch panels. Many aftermarket switch panels, consoles and housings are designed around this format, making switches with this footprint interchangeable across a wide range of compatible panels.

How does the ACX3705BL differ from the ACX1975BL? Both use the same 21x37mm Carling-style mount. The ACX1975BL is rated at 20A and has a blue LED illuminated indicator. The ACX3705BL is rated at 16A and is non-illuminated. Select the ACX3705BL where LED illumination is not required, and the ACX1975BL where a lit indicator is preferred.

Does this switch work on both 12V and 24V systems? Yes. The ACX3705BL is rated for both 12V and 24V systems, making it suitable for passenger vehicles, 4WDs and commercial vehicles without needing separate part numbers for each voltage.

What is the maximum current this switch can handle? This switch is rated at 16A. For loads exceeding 16A, use the switch to trigger a relay rather than wiring the load directly through the switch contacts.

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