Take a look at some key indicators that a limit switch might be appropriate for your application.
Considerations include aspects as simple as size through more complex options like sensor output requirements. Review how to select a limit switch.
Select the appropriate contact configuration for the application
Switches that operate and actuate in both clockwise and counterclockwise directions. When the switch operator moves clockwise to the Operate Point, one set of contacts close. If the switch operator moves counterclockwise the same number of degrees to the alternate Operate Point, the other set of contacts close. With this type of limit switch, direction of operation of a machine can be detected
Specialty switches, rotating the switch operator 10 degrees actuates one set of contacts, and moving the lever operator to 20 degrees (in same direction) actuates the second set of contacts. With this switch, physical attributes of the object (height, orientation, position, completeness of assembly) can be determined and subsequent segregation or control automatically provided by a single limit switch.
Switches that have no spring return mechanism - the weight of the operating lever provides the force to return the actuator to its free position. Gravity return switches are usually mounted with the operating head upside down.
Specialty switches that actuate with high precision and typically very low actuation force.
Pre-assembled at the factory and is epoxy-filled in order to provide the highest possible level of sealing for the most extreme application environments.
Switches with built-in indicating lights that provide information on switch status
Switches designed to contain any transient explosion within the switch itself and thereby operate in areas that require explosion-proof ratings
Switches designed for use in machine guarding and other human safety applications.
