Switches are commonly used in industry and can be separated according to their use into 5 types as below.
1) Toggle switches are operated by a lever to control the on-off status or direction of electrical current. There may be more than 2 states, such as a light switch in the building or a switch to adjust the wind speed of the fan, etc.
2) Push-button switches are used to control 2 positions on and off, both Momentary switches and push-and-hold (Alternate) switches are available.
3) Selector switches are used to control the direction of electric current in many directions. Their shape is like a hand knob. The selector switches are used to select the operating mode of the machine.
4) Limit switches are operating by the lever. The limit switch will activate when the moving part touches the lever of the limit switch. The limit switches are used to limit the distance of the moving part. To not allow the movable parts to pass into prohibited areas.
5) Proximity switches are switches that activate by using magnetic inductance. Proximity switches are used to check the avability of the object at the desired position.
