hazard light switch

Post by garyinwestoz »

Im wondering about Hazard light switch

Image


Do they vary model to model, country to country.

I have 2 different sorts,so Ive answered my own question - I suppose -
Whats the functional difference?

Image

I bought a new one from Schmeidmann recently, for $32 US, this the part number for my car (76 525 RHD)

Image

Can the red inner button be purchased separately from somewhere? I have 2 that need the red button.

76 525 - 4 speed, LPG and holley carb- restoring
77 528i- 4 speed manual
77 528i -4 speed manual getting rusty

80 528i auto - ready to relicense

Gary,

I’m not 100% sure, but cosmetically I believe new ones use the international triangle symbol for hazard and originals say “Hazard” like in your picture. I believe they’re functionally the same.

The difference I see in the 2 hazard switchs is the rear terminals. same number of prongs but the other one has an extra plate connecting an inner "pin"

My haynes manual electrical chart says No 52 - which indicates 6 lines to hazard switch

Beyond expected cosmetic differences, there are definitely regional differences in functionality.

I naively bought a U.S. spec hazard light switch for my German-spec Euro car a couple years ago. These two parts actually differ by one pin, so definitely no substitution....won't even fit in the female socket.

I haven't dug into the schematics, but the hazard switch is intimately tied into many of the lights, apparently, which would
seemingly explain why there are so many pins. Parking light configuration is distinctly different between the Euro and U.S. cars, which factors into this too.

However... I put a Euro switch in my US car. Works like a champ despite the physical differences re the extra pin. Just had to swap out the buttons.

Euro to US might work, but not US to Euro. :?
