im building my first 5v mod. i already built 2 3.7v boxes so its time for me to step up. does it matter what switch i used? my first two mods, i used the push button switch. i just order two switches, the horn switch and tactile switch. i dont really like the push bottun switch, it misses sometimes and i already broke it. the plastic button came out. so for a 5v mod, which switch will give me the best result? the horn is rated at 12v and 5 amps and tactile is rated at 12v and 5 ma. im guessing ma stands for milliamps.
