4A Overdrive Switch


Recommended Posts

Hi Folks,

over the last few months some posters have had concerns over new repro OD switches.

Recently mine has had a clunky feel to it when deselecting OD.

Today I decided to have a look rather than wait till October and repair it in a Scottish Glen in the pouring rain.

 

There was evidence of a small amount of arcing on the open off contact that was causing the little slider to pick up on it.

A little dab of copper ease grease has given it a new lease of life.

 

Perhaps a capacitor across the contact may help to reduce the arcing (caused by the coil in the relay, maybe).

 

Roger
