These can also be used for 2-way control with another SPDT.DPDT and DPST (double pole) are essentially two switches tied together and actuated simultaneously. One side can be used as simple on/off switches (same as SPDT or SPST) or to switch both negative and positive at the same time. Also wired as reversing (polarity reversing) switches.SPDT with center off means the there is a middle position that is not connected to either output Lighted switches means the light comes on when the load is energized.
