Its got one output and one input. Connect the live line or phase wire to the lower terminals of spst 1 way and spdt 2 way switches.

Spst switch wiring diagram. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. Also relays can be used to switch higher draw accessories to reduce switch load and voltage drop. Spst switches should only require two terminals. Do the proper earthing and grounding according to your local area codes. Pole refers to the number of circuits controlled by the switch. Spsts are perfect for on off switching.
What do spst spdt dpst and dpdt mean. 1 terminal is for the input. You can see that a spst toggle switch only has 2 terminals. The diagram below represents the schematic diagram for a spst rocker switch. We will now go over the wiring diagram of a spst toggle switch. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw.
The other terminal is for the output. Spst toggle switches function as simple on off switches. A single pole single throw spst switch is as simple as it gets. Sp switches control only one electrical circuit. The switch will either be closed or completely disconnected. Below is the wiring schematic diagram for connecting a spst toggle switch.
Spst toggle switch wiring. An illuminated rocker switch is like a spst toggle switch with an extra terminal which allows the light to work. Connect the lamp 2 to the common middle terminal of spdt switch shown by blue wire in the circuit diagram. Pin 1 is where the rocker switch receives the input power. Theyre also a very common form of momentary switches. You might want to review the article on toggle switch wiring before proceeding.
Pin 3 is where the switch is either connected to ground or left open. Pin 2 is where the accessory that the switch is going to turn on is connected. Connect the lamp 1 to the upper terminal of spst switch.
