What I've seen of these, the switch has 3 pins. 1...Power to the switch, 2....switched power to the load.....3....ground for the light. IF the switch has a lamp and NOT an LED, you could hook the ground terminal for the light to power instead of ground and it should work. The other terminal of the lamp is connected to "switched power to the load"
THE PROBLEM is that many (all?) of these are now LED, and LEDs are POLARITY SENSITIVE so the above trick won't work, at least not without a relay or other trickery. MAYBE if you look "deep enough" into electronics suppliers, you can find them with reversed LED polarity.
