Locked 1974 R90S Front Brake Switch

 

I replaced the brake and clutch switches on my ¡®74 when I restored it about 10 years ago and it recently stopped working. It started working intermittently after removing it and playing with it for awhile. I?bought a new one because I thought the old one might not be reliable now.

This seems like a short life. Is there anything I can do to extend the life on the new switch or revive the old one. I was thinking maybe squirting some DeoxIT Shield down the plunger or something like that. These are quite expensive now, $60 compared to $22 10 years ago.
 

The switch is commonly available at NAPA for about $13.00 or less It is made by Echelin and is also for a VW Beetle and also fits the 1961-1968 Jaguar E-Type. Just take the switch to NAPA and they can find one.
$60.00 for that is highway robbery.
 

I found the part ifor the brake light switch. it is ECHLIN 143
 

The 1974 R60/6 has mechanical brake switches. Both front and rear similar to the /5 series. The NAPA/Echlin switch is for a hydraulic switch similar to the R75'6, R90/6 & R90/S models. Below are pictures of the R60/6 switches.

To clarify, I was talking about the front brake switch for a ¡®74. It is a mechanical switch, same as the /5. Hydraulic switches like the?ECHLIN 143 started in ¡®75. I already received the new switch from Vech. I¡¯ve squirted a little DeoxIT shield down the piston. Hopefully some got to the contacts and will help make it last longer.
