Button switches, selector switches, rotary switches, and transfer switches are all common switches. A switch is an electronic component that can open circuits, interrupt current flow, or cause them to flow to other circuits. So what exactly is the difference between these three types of switches?
The push button switch is actually a single pole single switch. The switch is connected by pressing the switch to turn on the power. Now the most typical example in life is the power switch on the main box of the computer. Turning the power on, the push button switch is widely used in current electronic products. In general, the “small handle” of the push button switch is a stick shape, and the length is about 1.5 centimeters.
Selection switch: This switch has only one small “handle” that can be pulled in several directions. This small “handle” is disconnected when it is in the most central position (that is, when the small handle is perpendicular to the switch). Pull the direction, then turn on different circuit power. It is often seen on the factory's industrial machines.
Rotary switch: This kind of switch looks like a button and turns the switch on or off by rotating it in different directions.
Changeover switch: Generally speaking, this switch has the function of selecting which power supply to use when it is powered by multiple power supplies. This switch is not a simple switch but a power selection device.
