Silver Contacts Elevator Electrical Limit Travel Switch with Big Plastic Wheel Contact Parts for Elevators

Plastic Big Wheel Silver Contacts Elevator Electrical Limit Travel Switch

The plastic wheel adjustable arm self-reset structure in the travel switch limiter is a common design. The following is its related introduction:
Structural featuresWorking Principle
When the stopper (bump) of the moving machine presses onto the plastic large wheel of the travel switch, the large wheel rotates under pressure, driving the adjustable arm to rotate together with the shaft, so that the arm pushes the bumper. When the bumper is pressed to a certain position, the micro switch is pushed to act quickly, thereby cutting off or changing the control circuit, stopping the moving machine or changing the operating state. When the stopper on the roller is removed, the reset spring resets the arm and the large wheel, the micro switch also returns to the initial state, and the circuit returns to a state that can be triggered again.
Application Scenarios
This type of travel switch limiter is widely used in various equipment and machinery that require position limitation and protection of moving parts, such as machine tools, cranes, automatic production lines, elevators, etc. In elevators, it can be used to control the upper and lower limits of the car to prevent the car from exceeding the normal operating range; in cranes, it can limit the rising and falling heights of the hook, as well as the operating positions of the trolley and the car to ensure the safe operation of the crane.
