Can someone tell me how this switch works?

    According to the datasheet, in order to use this as a simple ON-OF switch, you''d need to connect to pins 2 and 1... pin 3 appears to be connected to pin 2 through a 100kΩ resistor and a light.....

    1. Line in.
    2. Load.
    3. Neutral.

    The neutral connection to pin 3 is needed to complete the circuit to power the neon illumination.

    Yeah tried it but nothing happens, The switch may be dodgy, Im not sure but I just used 5VDC.

    Many high current switches have silver contacts. Silver corrodes and will not pass a small voltage or small current because it needs the arc from a high voltage and current to burn away the corrosion.

    I always used gold contacts on switches and relays for low voltage and low current switching. Gold does not corrode. The thin gold plating costs the same as thick silver plating.

    If you are referring to the light not working,it won't, it looks like a neon bulb which requires about 70 volts and up.

    So can an alternative switch be recommended that uses low DC voltages around 5-10V?

    The switch using in AC And DC circuit maybe as below:

    Is the switch turning the 'load' on but the light not working?
    How much current does the load draw? or what is the load?
    Do you have access to a meter?

    Answer these and we might could help you

    You need a switch that has a low voltage LED, not this switch that has a high voltage neon bulb.
