What is an actuator?

ID: FAQE20010E



An actuator is a component that transmits external force or movement to the internal mechanism of a basic switch. The mechanism consists of a pushbutton and lever.


An actuator transmits external force and movement to the internal mechanism and is also useful for making the stroke longer and reducing the operating load (operating force) to make the switch easier to use. The table below shows their types.
Many different types of actuators can be attached to the actuator depending on the shape and movement of the detection object, based on a pin plunger. Select the actuator that is best suited for the shape and movement of the detection object.
