My pressure switch for the brake lights is dead. I was reading some old threads and it seems a few people have put switches on the brake pedal. Anyone have part numbers or a picture of how / what you did? I was thinking about mounting a little micro switch behind the pedal on a spring, Anyone know how many amps the switch needs to handle?

add the wattage of the 2 bulbs together

then divide by 12

P = IR

Power = Currant times Voltage

hope this helps

I went through three of these switchs in the past - last one has lasted for a couple of years though.... I find Its a lot easier to replace the switch... but if you wanted to put a seperate switch in, the amp rating would be tiny, especially if you used LED stop light bulbs as I do, the power drain is square route of naff all......

I replaced my switch with an industrial pressure switch which is adjustable. This solved the other problem where other drivers were complaining that the lights did not come on until I was quite heavy onto the brakes.
The AP brakes are that good you need to give the guy behind fair warning that he's about to ram you.

do you have any info on the switch you have? Is it a direct replacement?

The switch was like that from the start but until you drive the car you don't realise how little pedal pressure you use under daily driving.

I bought it from a UK outlet but would be pretty sure they don't make the switch.
It's PMN 10AE 1/4P Stl see data sheet www.pvl.co.uk/. If you mail them they may tell you the manufacturers name so you can source it out there. It cost me £15.60 with tax and delivery.
I then had to get an adaptor for 1/4"BSP female to 3/8"UNF male. One of our local parts suppliers made it up for me by finding one in his range with the correct male thread but smaller female which he the tapped out to the required size.

All works a treat.

I agree with steve- these switches work a lot better and can be easily adjusted for pressure

it says it's only good for .5amp, is that enough.

Not being electrical by nature I asked a friend. Two 21watt brake light bulbs is going to be nearly 4 amps. However mine seems to be ok and it's been in there since Nov. 04, how does that work?

Can't vouch for them, but you might try these guys in the US...
These guys, too...

Summit Racing has some, as does Painless Performance.
