The illumination is provided by a neon bulb, not an LED. The two silver pins are the switched pins (attach your load across these), and to light up the neon indicator light, apply 120V - 240V between the gold pin and either of the silver pins. Neon bulbs are not polarized, so it doesn't matter which side is hot. Note that the switch is internally a DPST switch because it doesn't matter which silver pin you use for powering the neon bulb. I posted a review with an image of the schematic of this switch. Please see that for more information. Δείτε περισσότερα
