Push button switch, selector switch, rotary switch and transfer switch are common switches. A switch refers to an electronic component that can open a circuit, interrupt current or flow it to other circuits.

So what is the difference between the three specific switches? Let's see!

The button switch is actually a single pole single position switch. The connection mode of this switch is to connect the power supply by pressing the switch. Now the most typical example in life is the power switch on the mainframe of the computer. As long as you press it, you can connect the power supply. The button switch is widely used in current electronic products, Generally, the "small handle" of the button switch is in the shape of a small stick, and the length is about 1.5cm.

Selector switch: as the name suggests, the selector switch is selective. According to the selection position, there are two position selector switches and three position selector switches, which are common. According to the reset performance, it can be divided into reset selector switch and self-locking selector switch. It is also one of the commonly used switches in the control circuit.

This switch has only one small "handle" that can be pulled in several directions. This small "handle" is disconnected in the most central position (that is, when the small handle is perpendicular to the switch). Pulling in different directions turns on different circuit power supplies. It is often seen on industrial machines in factories.

Knob switch: this switch looks like a button. By rotating in different directions, the switch is turned on or off.

Transfer switch: generally refers to the function of selecting which power supply to use when multiple power supplies are used. This switch is not a simple switch, but a power selection device.
