Application and Buying Notes

Before ordering, check the panel opening and mounting arrangement carefully. This switch uses a 12mm mount diameter with an M12 x 0.75 thread and a 3mm mount length, so it needs to suit the installation space as well as the wiring layout.

The electrical rating is 20A at 12V and 10A at 24V, so the switch should only be used within those limits. It has 2 blade terminals and 1 pole with 2 positions, so confirm your existing wiring and circuit setup match an On-Off SPST configuration.

The switch is non illuminated, so it will not provide a lamp or backlight indication. If your application needs visual confirmation, that requirement needs to be met separately. The supplied On-Off tab and metal body are useful details to check against your current hardware before purchase.

Because no vehicle fitment has been provided here, the safest approach is to compare the ACX3874BL part number, terminal style, and mounting dimensions with the original switch or the vehicle’s wiring specification. That is the best way to avoid buying a switch that physically fits the panel but does not match the circuit requirements.

If you are replacing an existing toggle switch, inspect the terminal count, the thread type, and whether the original unit was a 2-position on/off switch. Small differences in terminal arrangement or mounting size can affect installation even when the switch appears similar at a glance.

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 ACX3874BL 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.
