That's not the same switch you are looking for if you take a little off the end?
Recently had a similar situation where Marco listed my switch only as a reference, digging a little deeper I realized that I could simply
modify a similar switch they had.
My experience with faulty switches I'd say 90 % of the time the fix is a shot of DeOxit where the button is. I also check the switch with a multimeter both switch closure with continuity and the diode setting to check diode. I don't rely on switch test as an indicator of a bad switch as it may be a broken wire downstream.
