I’ve done a fair amount of research on the Lucas side managed to talk to a Lucas tech in the tech support group he informed me that it has been discontinued and none were left in stock. He was kind enough to put out a notice to their dealers asking if there was one left in stock. No luck. I asked if it could be rebuilt as I have the case and the toggle, missing a couple of springs and the brass sliders inside. They did not perform that service was his reply. I have yet to go into other English or Italian marques. I will begin to do so.



I want to thank all who have taken the time to offer their advise. Thank you

Bill

Bill, thanks--just curious--have you found anybody making just the old style knob?  I haven't tried to re-graft the knobs yet (I suppose they are like old guitar tuning pegs, just add heat to the metal first and the knob pulls off). But have been curious if just the round knobs are available.

At least, the repros should fix you up electrically--Lee

Thanks @leea I hadn't noticed that before, this is great!!!

@billpedersen and Everyone,  seems like you could make one of these work?

Here is a current ebay link  to one that looks like it would work.

Alternatively, you could use this.

and  this

so you could 2 step it to drive a DPDT relay...... pretty snazzy!!

Lee,

I remember seeing some for sale on a Maserati forum a few years ago.

Maybe we should just 3d print some.

This may be a solution, but way expensive:

These are Chrome, but could be a start:

but not as expensive as these:

Bill,

I believe that I had a two position (on-off) fan switch go bad, no surprise....no relay in the circuit, now there is....  If you can find a regular DPDT or even a SPST (if it fits the wiring!) like the one in the post above a bit..... You can swap the top of the switch or just the knob & arm.

Trying to pull the plastic knob off would likely damage it.....but you can take the top of the switch off, push out the pin and put the entire knob and lever into the new switch.

Be careful though, Lucas was the master of building switches with tiny things & springs that fly to the deepest darkest corners of your garage or kitchen floor when you aren't paying attention!!!!

Good luck!

Hi Bill, I think Denis and others have you covered with those switches but if they are single position and you need 2 position (?fan?) then I bought some NOS  in 2018 from Martin Robey in UK (I think they have US branch too).  The switches are same as a Mk 1 Jensen Interceptor (and possibly CV8 too).  The part number for the 2 position fan is CT 2481.

Also Maseratinet in Tacoma sell the 2 position, they also sold me a set of the stickers for end to identify what switch is for.  I believe the switches and stickers re same on Ghibli

On the Robey part but don't have a photo on their website of part so you'll need to double check it's not the blade type.  Occasionally they crop up on Ebay too.

The fans -should- have been 2 speed, but unfortunately just single throw..! You could always add a double-throw switch and a resistor if you wanted a second speed interior fan...all in all, just smarter to hook up a thermostat for the engine fans.

  The single double throw (3 positions) switch is used for the headlights--so functionally, very common and shared with motorcycles. The emergency switch is a two-pole switch--originally this used the Ghibli fuel pump switch (that switches between left and right tank, but of course you want one of the other...just ask my brother who ran out of gas on one tank on his Cessna during the last minute on approach... ). So this is a 2 position switch but dual pole (2 fully independent circuits, as it switches between even the 2 different blinker relays used for ignition On and ignition OFF modes).
