Application and Buying Notes

Before ordering, check that your panel cut-out matches the stated 37.5mm x 21mm mounting opening. The mounting length is listed as 37.5mm, so a close physical check is important where the switch is being fitted into an existing dash, console, or accessory panel.

The switch is rated at 20A at 12V only. That means the electrical load and system voltage need to suit the switch exactly. If the circuit is not 12V, or the expected load is higher than 20A, it would not be the correct choice for the job.

The listed switch action is Off - Mom On - SPST, which is a specific operating pattern rather than a general on/off rocker. Make sure that momentary operation is what your accessory or circuit requires before buying.

There are 5 terminals and push-on terminals, so confirm your wiring setup and terminal style against the existing switch or the wiring plan for the vehicle. The blue illumination with “Dash Light” and “On” lighting may also matter if you want the switch to be visible and matched to other illuminated controls.

The weight is 0.04kg and the unit is supplied each, with a one year warranty listed. Those details do not replace a fitment check, but they do help when comparing the switch against other options or planning multiple installs.

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 63127BL 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.

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 and output 20 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
