Here are three more switches: They are called "Slide Switches". There can be many configurations of switches. Pins 1 & 4 would be one side, pins 2 & 5 would be the common (center) connection and 3 & 6 would be the other side. I don't have an illustration for such.Ī switch known as a DPDT (Double Pole Double Throw) will have two sets of these contacts internally, just three more pins. If it's a momentary switch one of the two "On's" would have a circle around it. The third is SPDT "Center Off" - or On-Off-On. But if you push it the other way it switches and maintains that position. OR it could be spring loaded in just one direction and spring back to center. It could be loaded that no matter what the switch always comes back to the center position as shown in the third illustration. Those are known as "Momentary" type switches. The third switch shows a switch with "Center Off", meaning pin 2 is not connected to anything.Įach switch has a spring where you toggle the switch one way or the other and spring back to the center (third switch). ![]() The second switch is shows pins 2 & 1 in contact with each other. The first switch is shown connecting pin 2 to pin 3. ![]() One would be the normal operation of switching between 2 & 3 or 2 & 1. It can be configured in many different ways. Each switch is an SPDT (Single Pole Double Throw) type switch. Here are three switches showing their insides.
