fixing a switch

[Philip]

I just have to sing the praises of a great product called "Mr McKenick Electronic Contact Cleaner". I have used it on all sorts of jobs - tow hitch connectors, electric seat switches on my old LR Disco and now on a non-fucntioning TR7 light switch. On Saturday only the sidelight would come on - the lamps wouldnt lift and wouldnt light - the flash switch lit the lamps but didnt lift them.

I removed the switch, took off the cover and sprayed copius amounts of the cleaner into the contacts. Today the lamps are working normally.

I will still fir a new switch, but now I can keep the old one as an emergency standby.

On a different subject - I changed the stering column bush on Sunday. The "old" bush was a piece of radiator hose held in place with two jubliee clips. Nice easy job - I boiled the new bush for ten minutes and it just slipped in.

Still standing !

Boiled bush indeed! Nice. Handy tip!
WD40 does a very similar job on switches.

I like to put dielectric grease on switch and electrical contacts after cleaning as well as it would prevent corrosion in the future. Many contact cleaning aerosols would likely leave a film behind preventing corrosion but I feel the grease would be a more permanent solution especially in moist environments.
