tyDoes it say aything about "flammable"? When last I looked -- admittedly some time ago -- contact cleaner contained alcohol and Freon™.
I'm quite sure the propellant is something different today, but I still wouldn't recommend it. Many modern refrigerants (propellants) are flammable, and a flash fire is only half your problem; incomplete combustion is also likely, which will leave carbon soot on the contacts.
Good grief! We would have been sacked for having a lighter in the industrial world we lived in!Got a lighter? Hold it up to the spray (safely pointing it away from everything) and see it it ignites. I’m going to bet that it does…
Also, being a float switch, it might be moisture intrusion. I would first do a quick spritz if WD-40, which is a water displacer (that’s what the WD stands for) and is electrically inert. But don’t spray that live either.
Safest bet is to never spray ANYTHING around a live electrical circuit.
This case arises from a tragic accident involving
appellant Faberge's hair spray product, Aqua Net. The appellee
Alison Nowak punctured an aerosol can of Aqua Net near a flame
and suffered severe injuries from the resulting fire. The jury
found that a defective valve system and inadequate warnings on
the hair spray can proximately caused Alison's injuries. She was
awarded damages of $1.5 million.
Lawyer around the corner from me won a 1.5 million judgement for a teenage girl that got badly burned by hairspray because it used propane for propellent.
You really have to be careful with aerosol can propellants
Non-conductive wasp spray exists specifically for use on live apparatus. Is it also non-flammable? I don't know.... Safest bet is to never spray ANYTHING around a live electrical circuit.
I looked up the SDS of two brands I have bought in the past and what's currently in my kit (Spectracide Pro, rated to 47kV). All flammable.Non-conductive wasp spray exists specifically for use on live apparatus. Is it also non-flammable? I don't know.
There may be a non-conductive and non-flammable contact cleaner out there, but why would anybody consider working on live equipment when it isn't absolutely necessary?

I really only use that kind of stuff to clean out gunk and dirt that is binding the mechanical operation. of contactsI was a maintenance electrician for 50 enjoyable years and spraying float switches and other controls are at best a short temporary fix. Best to replace it. I ripped a Ford so called mechanic when he told me that he fixed my brake switch by spraying contact cleaner on it. Less then a week later his so called fix failed.A few days later after complaing to Ford they told me they just came out with a recall and they would replace the brake switch. Only time that I used contact cleaner was on an old starter contact that we did not have either a replacement starter or set of contacts. Would use a contact file to clean contacts then spray but always replaced them ASAP.

Never spray anything on energized circuits.
I just use 99% IPA as contact cleaner and the method pton described in post #5.
