How does a neon indicator work in a light switch that has no neutral connections ? Supposedly, the neon indicator is 'alight' / on when the luminaire is off and vice versa. With a 1 way switch, I presume the indicator neon connections would be between common/line/live and L1 (is there any other option) but in the case of 2 way switching this would become more tricky as you would have common + L1 / L2 to choose from. If the indicator were to work as above, eg on when luminaire off and vice versa, how would you wire the actual neon connections ?
PS does a neon indicator bulb / wiring set itself have polarity ?
