Application and Buying Notes

Before ordering, check the panel opening carefully against the listed mounting dimensions of 37.5mm x 21mm. The switch is designed around a 12V electrical system and carries a 20A rating, so it should be matched to a circuit that sits within those limits.

The 5-terminal, push on terminal layout is useful to know before wiring begins, as it affects how the switch is connected in the vehicle or accessory loom. The SPDT configuration and 1 pole, 2 position design should also be compared with the switching function your accessory requires.

The blue illumination includes both 'Dash Light' and 'On' illumination, which helps with switch visibility in the cabin. If you are replacing an existing switch, compare the part number 63145BL, the Off/On action, and the light bar symbol so the replacement matches the intended function and appearance.

This switch is listed as sealed, but the exact installation environment still matters. Check that the physical size, terminal type, illumination style, and electrical rating suit the accessory you are fitting, especially where the switch will be used for a light bar or other 12V accessory circuit.

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 63145BL 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.
