Hey All, I needed to replace a toggle switch on my Spit, so went to an auto parts store which had switches (common automotive electrical part company) almost identical to the original Spit switches. The package said a rating of 12v at 15 amps. Great. Upon getting home and opening the package, the markings on the switch said 3 amps at 250 volts AC. In my youth (many, many moons ago) I dabbled in electronics and back then the dogma was that one didn't mix AC and DC switches. Something to do with the composition of the contacts in the switch, the DC contacts being engineered for current running in one direction only whilst the AC contacts were engineered for current going back and forth only. Not a question of wattage. Are new switches AC-DC? Any electrical engineers out there who can speak to this?
