OEX Carling Style Rocker Switch On/off Spst Blue Illumination 20A 12/24V ACX1975BL

The OEX Carling Style Rocker Switch is an illuminated On/Off SPST switch with a 20 amp power rating and 12 or 24 volt compatibility. It is identified by part number ACX1975BL and is supplied as a single switch unit.

This switch uses a rocker action with 3 terminals, 1 pole and 2 positions. The lamp colour is blue, and the listed mounting hole size is 21 x 37 mm, which is the key sizing point to check before installation.

For anyone replacing a dash, accessory panel, or auxiliary control switch, the important match points are the switch action, terminal count, voltage, amperage rating and mounting hole dimensions. Those details are specified here and should be checked against the vehicle or panel layout before ordering.

Application and Buying Notes

The most important buying check for this switch is the mounting opening. The listed hole size is 21 x 37 mm, so the panel or dash opening needs to suit that dimension for the switch to sit correctly. If the opening is different, the switch may not seat as intended even if the electrical rating is suitable.

Electrical compatibility also matters. This unit is rated at 20 amps and is suitable for 12V or 24V systems, so it should be matched to the circuit voltage and the load it is being asked to control. A switch should always be selected with the wiring and accessory demand in mind, rather than only by appearance or illumination colour.

The switch action is On - Off - SPST with 3 terminals and 1 pole, which is a straightforward configuration for single-circuit control. That makes the part number ACX1975BL, together with the terminal count and switching style, the best reference points when comparing against an existing switch or planning a new install.

Because this is a blue illuminated rocker switch, it can be useful where a visible indication is wanted at the dash or accessory panel. The light colour is blue, but illumination alone does not confirm the wiring arrangement in every application, so the terminal layout should still be checked against the circuit before fitting.

This switch is sold individually as an each item and carries a one year warranty. If you are replacing a damaged or worn switch, compare the old part carefully against ACX1975BL, including the rocker style, 3 terminals, 20 amp rating and the 21 x 37 mm mounting size, to reduce the chance of ordering the wrong component.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number ACX1975BL helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Carling Style Rocker Switch On/Off SPST Blue Illumination. Part number ACX1975BL should be checked first. Listed voltage is 12 or 24. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number ACX1975BL, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 or 24 and output 20 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by checking part number ACX1975BL, the 21 x 37 mm mounting hole, 3 terminals, 1 pole, SPST On/Off action, and the 12 or 24 volt, 20 amp rating against your existing switch or panel requirements.
