So, thanks to all of the posters, it IS indeed the micro-switch in the hand brake. At least, we're 99% sure of it.

Now...what's the best source for one? If anyone has replaced it and has info, it would make the hunt much easier I know. TIA!

 

A quick google of the part number brings this up:
https://www.britishparts.co.uk/produ...dbrake-DAC3351

Apparently this one also works: Low Cost Standard Microswitch with Roller | Maplin

 

Thanks. The Maplin switch is only available to those in Ireland or the UK. I've sent a note to the other company - theirs is significantly more expensive, but may be the only one available :-(.

 

That's a common microswitch. They are used in dental equipment as well of countless other applications. I've picked them up at local electronics stores here in Canada.

 

That's good to know! I think I may have found one here, also:
Welsh Enterprises
800-875-5247 EXT 165
740-282-8649 ext. 165
740-282-1913 fax

 

i'm looking for this switch too, but i suspect the DAC3351 is for the coupe. my convertible has a parking brake interlock for the droptop and there are three leads. this switch only has 2 spades on it. if anyone knows the part number for the switch with 3 spades, i'd be much obliged.

 

I just bought one two weeks ago from Coventry West.

Coventry West - Jaguar and Land Rover Parts

Wasn't expensive, but I forget exactly what I paid since I bundled it with a few other things. It was used, but it worked great.

 

Correct. That Britpart switch is not the right one for any model. I bought one and found out the hard way. I told them but they did not believe me!
As you said, you need a three terminal microswitch which are NLA in the UK at least from Jaguar and the specialists. I ended up buying a pack of these:

The one from Welsh DID work btw....

 

i ended up ordering this. it's a 16 amp switch like the DAC3351, but it's a Single Pole Double Throw. I expect to have to bend the actuator.

i couldn't find the switch on their site. i'm curious as to the Jag part number for the one you bought.

 

I think this will not do it, certainly will not on pre-facelifts. You need three terminals.

 

there are three terminals on it, the ground terminal is on the bottom edge.

 

I think this one might work too: https://www.digikey.ca/product-detai...1C5-ND/2754900

Or this one: https://www.digikey.ca/product-detai...378-ND/1824838

There are lots to choose from.
