1994 Esprit S4 ABS Switch HELP!

[euroteck]

I have a 1994 Lotus Esprit S4 with the typical ABS pump issues. We've isolated the problem to the switch. From what I understand, these switches are not to be found. Jeff at JAE has been telling me for 3 months that he has me a new ABS pump system coming but I have my doubts whether this will ever pan out. At this point I just want it back functional - anyone have any idea of where to find a system that will work and/or a switch? Any help would be appreciated. I put pics below of the pump itself then a closeup of the switch. Thanks.

Have you tried cleaning the switch? Some have reported success using that procedure as was posted here a while back. Do a search and you should be able to find it.

There's also a gent in Australia who has come up with an alternative switch. Again, search and you shall find...

Zach,

if you wish I sell a whole PUMP with new SWITCH for 250 Euro plus shipment.

The switch is NOT the original one, but an alternative switch I found.

This switch closes below 2200 psi and closes at 2700 psi like original one.

But the second contact that opens below 2200 psi is missing (this is the special feature of original one)

I do not sell only the switch.

Thanks to everyone for the help. I have tried cleaning it and I will check out the alternative switch thing. Nicola - feel free to message me - I would consider purchasing the system you have. Thanks

I tried to call the number for Steve in Australia and it went to a generic voicemail - hopefully I have the right place. Anyone have an email address or website for this guy? Thanks for the help!

It might be worth asking around local garages / workshops to find someone with an ultrasonic parts cleaner - that did the job for me.

Zach,

I'll get in conact with Steve and ask if I can post up his email. I don't think it will be a problem, but I need to check first.

Michael.

He responded to my voicemail and emailed me. Thank you though!
