The switch is symmetrical and bidirectional, so it can be connected on the high side or low side and used with AC or DC supplies.
For inductive loads powered from a DC supply, a flyback diode (also called a freewheeling diode) can be connected across the load as shown below to reduce inductive voltage spikes when the switch turns off.
