Multi-gang integral switch YSR-9JD-4H

Single-gang switches are single-pole switches.  In fact, they should be said to be single-pole single-gang switches. A double control switch is a control switch with two positions that control a circuit at the same time. For example, you can control a staircase on the first floor or on the roof. Double control switches must appear in pairs to make sense. The difference between unipolar, bipolar and three-pole switches is a matter of naming. Single, double, and triple switches are also called one-on, double-on, and three-on switches. A single is actually a switch with only one button, a double is a switch with two buttons, and so on.
