I got one of those vandal led (black w/ white ring) switch to control my leds on my fans. The switch has the layout of +/- for leds and 3 tabs labeled nc/no/c. I can't figure out how to wirie it in. I'm coming from a led rocker switch that only has 3 tabs. I don't get how there explaining this. I connected wires in both ways but switch doesn't turn on nor do the fan leds turn on. left is common and right is push-down Only searches I can find is on using these as reset switches.
