Gearbox switches

[ahebron]

I dismantled two gearbox overdrive/reverse light switches as they had no continuity.
Tap open the crimped parts at the top and the plate should popout.
The first crimped all round the edge and was full of oil so I drained it and cleaned everything then a light grease over the sliding parts before reassembling and gently tapping the aluminium edge back around the switch.
The other one was crimped in three places and the contact plate looked like it had possibly been arcing on its contacts. Clean everything and file the contacts and a light grease over moving parts before reassembly then restake the edges in 3 places.

Both switches working well but I would only use them as overdrive switches as the one with oil was most likely a reverse switch that had taken oil in past the plunger.
