Product Introduction:

TSA-081 Metal Housing Waterproof Elevator Limit Switch

Travel switch is also called position switch or limit switch. It can complete travel control or limit protection. Its function is the same as that of the button, except that the action of the contact is not by manual operation, but by using the block iron on some moving parts of the production machinery to collide with the roller to make the contact act to connect or disconnect the circuit

In the selection, mainly according to the application and control object. When the speed of mechanical movement is slow and the current in the controlled circuit is large, considering the difficulty of arc breaking, the travel switch with fast action can be used. When there are many loops of the controlled object, and it is not suitable to install the direct acting travel switch on the path of the production machinery travel, the direct acting travel switch can be used

Select master controller type (i.e. camshaft rotation type) travel switch. If the working frequency is very high, it is not suitable to install the friction block on the production machinery, and the reliability and accuracy are also high, the appropriate transistor proximity switch can be considered.
