I, on the other hand, prefer a nice simple analog switch on my electros. Not a mash the button and hope it turns off, no a "switch is this way for on, that way for off" is what I like. You can tell the state of the gun at a glance (is my battery dead, or did I mash the wrong button to turn it on?), and it isolates the battery from the board completely so the last a bit longer.
