Waterproof Electrical Limit Switch

Product Introduction:

TSA-031 Metal Shell Rollers Types of Electrical Limit Switch

The travel switch is used to limit the position or travel of the mechanical movement, so that the moving machineryautomatically stops, reverses or automatically moves back and forth according to a certain position or travel.

There are many kinds of travel switches. The commonly used travel switches are button type, single wheel rotarytype and double wheel rotary type. The button type and single wheel rotary type travel switches are automatic reset, similar to the button, so they become self reset travel switches. The two wheel rotary travel switch is callednon self reset travel switch because the contact is reset after collision with the direction.

The travel switch is used to limit the position or travel of the mechanical movement, so that the moving machineryautomatically stops, reverses or automatically moves back and forth according to a certain position or travel.

From the design point of view, it is widely used in all kinds of machine tools and lifting machinery. We need to understａnd that it is used to control its travelａnd carry out terminal limit protection. In the elevator control circuit, the travel switch is also used to control the switch Speed of car door, limit of automatic door opening and closing, upper and lower limit protection ofcar. The travel switch can be installed on a relatively forbidden object (such as a fixed frame, a door frame,) or a moving object (such as a traveling crane, a door,).

When they approach, the connecting rod of the switch drives the contact of the switch, causing the closed contact to open or the open contact to close. Action withoutcontrol circuit and mechanism.
