Brake light switch FIXED

[Welshy_Pete]

Hello the brake light switch works on my spare 306 hdi. But when you pull the switch out more it clicks each time in to place. You then release the brake pedal so the switch a just to the pedal. 

It works for a short time but the switch ends up going back a few mm to far. But if you hold the brake pedal back up foot underneath a few mm the brake light switch works.

So I'm thinking what's the best thing to do here with the switch working but this problem with it moving.

Thanks
