This switch
http://terminalsupplyco.com/Store/Pr...x?pc=MLR-AMBER
has terminals marked "PWR ACC GRD". How should it be connected?

I'll speculate that PWR & ACC are for the circuit and GRD is for the
lamp.
If GRD is connected to the neutral conductor, the lamp is on when the
switch is closed?


** That switch is strictly for 12 volt DC circuits.

The 12 volt lamp inside is connected across PWR and GND - so when the
switch connects the battery ( ACC) to the load it lights up.
