Hafod Posted October 28, 2023 Share Posted October 28, 2023 Does anyone have the brake light switch Partode / type that fits the brake Union near the master cylinder. I have no brake lights now but still have the 12v feed to the switch. Quote Link to comment Share on other sites More sharing options...
Ian Kinder (Bagpuss) - Joint Peak District AO Posted October 28, 2023 Share Posted October 28, 2023 Hi Phil, If you join the two wires at the switch, do your brake lamps light? If so, you'll need one of these- Pressure switch Quote Link to comment Share on other sites More sharing options...
Hafod Posted October 28, 2023 Author Share Posted October 28, 2023 Thank Ian, yes have power so suspect the pressure switch is n/g. I’ll get a new one on order thanks phil Quote Link to comment Share on other sites More sharing options...
Dave Eastwood (Gadgetman) - Club Chairman Posted October 28, 2023 Share Posted October 28, 2023 Though to be fair, all the in-line pressure switches seem to be poor and fail regularly. In the end, most of us end up leaving them in place, but fitting a way more reliable mechanical (micro) switch to operate the brake lights. (There are files to 3d print great little mounting brackets for the switches, if you have, or know someone with access to, a 3D printer. Or they're easily made from some angle section metal, aluminium, steel etc. Quote Link to comment Share on other sites More sharing options...
Dave Eastwood (Gadgetman) - Club Chairman Posted October 28, 2023 Share Posted October 28, 2023 Here's the one done by @Greenstreak-Andy D I've used it, as have a few others. Works well. 1 Quote Link to comment Share on other sites More sharing options...
Matt_S Posted October 28, 2023 Share Posted October 28, 2023 Im planning on changing mine and using the same design as Mofast used to produce which bolts to the floor. This is the micro switch they used. Quote Link to comment Share on other sites More sharing options...
Alan Cutler (Adge) - Dorset AO Posted October 28, 2023 Share Posted October 28, 2023 My press. switch is/was still working, needed a good push of the pedal to get the lights on though, so I’ve added a micro switch operated off the pedal and wired in parallel with original switch. Now adjusted so lights come in with minimal pedal press, much better in traffic now IMHO. I used the micro switch listed in Greenstreak Andy’s write up above and and made a mounting bracket and actuation tab from aluminium. PITA working in the footwell at my age though! Wiring was straightforward, just connected into the brake light wire on the Blinkstop unit behind the dash. 1 Quote Link to comment Share on other sites More sharing options...

Hafod Posted November 10, 2023 Author Share Posted November 10, 2023 Help, the puzzle continues I bought a new brake pressure switch, a Lucas one but it turned out to be the wrong thread but this is not the issue. when I used a jumper wire across the brake switch connections the brake lights only come on when the sidelights are on. Side lights off, no brake lights using the jumper wire. My Westfield is an FW with the ring LED combined side / brake lights so I guess it’s just a higher voltage when the brakes are pressed. Does anyone have any idea what might be wrong? Quote Link to comment Share on other sites More sharing options...
