I am not a fan of a mechanical switch substitute for the original hydrauic brake light switch. However, in light of a recent rash of bad hydraulic switches, this change seems to be somewhat popular. Mike Ellsmore sends these photos and notes showing the way he did it.


Switch used was a Taiwan made copy of a stanadard Micro Switch.

"An alternative brake switch set up for the MGA. I grew tired of changing the faulty pressure switches so had a plate made for mounting a modern 'release = contact' switch. As soon as I brush the brake pedal now the lights are on. I copied one I saw through browsing Google so not my idea but a great solution for the non-purists among us". ----->

"I made a "quick and dirty" installation for a mechanical brake switch just to see how it would work. It's still working just fine 18 years later. The switch was from NAPA for an American car from the 1960s. Just look in their book for a switch that fits your mount".

Here's one, below and to the right, taken from a Facebook note:
The switch is SPSTNC (Single Pole, Single Throw, Normally Closed), push to break. It is a generic standard old brake light switch from any auto parts supplier.

"My mechanical switch has a built-in swivel which is perfect for where I mounted it onto the outer casing of the steering column, down by the pedals. I pop-riveted two jubilee clips to the base plate of the switch which I clamped onto the steering column, I used some very thin rubber around the column to protect the paint on it.

The pull spring on the switch attaches to the brake pedal and I made a clamp to fit to the pedal arm because, for safety reasons, I didn't like the idea of drilling a hole in such a structurally important brake component. Everything about this switch just clamps into place and no extra holes are drilled anywhere". -- Colyn
You can push the button on front end, or pull the spring on the rear end, as it is the same rod through the switch.
