Satisfying clicky video of the inside of the switch.

K&L switch mods

Generally K&L stuff is quite good, sometimes better than OEM.

This seems like an exception.

The casting on the K&L switch is not quite the same, and one critical dimension is wrong enough to require modification.

In the first picture, that angle on the OEM switch is necessary to clear the brake master cylinder's casting. Without it, you can't get the mounting screw in.

The different shape casting isn't solid, so when I cut away the plastic to fit it left a hole. There's nothing important behind the hole, so I fixed it with JB Weld.
