Every time you get that pop, it's burning away a little more of the contacts
inside the switch. At some point it'll stop working properly and need to be
replaced. A better grade of switch, like spec grade, or a heavier rated
switch such as a 20 amp, will have more substantial contacts, and will make
a more positive connection, so it will be less likely to make a pop, and
will last longer
