Dp switches control two independent circuits and act like two identical switches that are mechanically linked. Connect the lamp 1 to the upper terminal of spst switch. Pin 1 is where the rocker switch receives the input power. A single pole single throw spst switch is as simple as it gets. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. Sp switches control only one electrical circuit.
The other terminal is for the output. Spst switches should only require two terminals. Connect the live line or phase wire to the lower terminals of spst 1 way and spdt 2 way switches.
