I’d say ‘don’t be surprised if there is no reset button to push’ … I have 3 old 914 master cylinders and none of them have a reset button. Am I missing something? They all have some type of a square plastic “tower” where the spade(s) are … is that somehow the reset “button”? I lightly tried prying the plastic block off on one and that didn’t seem to be the case (IMG:style_emoticons/default/confused24.gif)



Not all switches have the latching function and the reset button. The later model two pole switches are not latching - when there is a problem in the master cylinder the pressure differential between the hydraulic circuits will cause the light to turn on.

If you’ve converted from an early single pole to double pole switch (or vice versa) it needs to be wired accordingly.
