A hinged roller limit switch is a type of electromechanical switch that is used to detect the position of a moving object and activate a circuit when the object reaches a certain point. It consists of a switch body with a hinged arm that is attached to a roller, which is designed to contact the moving object. When the object activates the roller, the hinged arm is pushed down, activating the switch and closing the circuit.

The hinged roller limit switch is typically used in applications where the position of a moving object needs to be monitored or controlled. It can be used, for example, to detect the position of a conveyor belt, a door, or a machine component. The hinged roller limit switch is designed to be rugged and reliable, and it is often used in industrial environments.

The specific characteristics of a hinged roller limit switch can vary depending on the manufacturer and model. For example, the hinged roller limit switch you mentioned (1A, 125VAC) has a rated current of 1 ampere (A) and a rated voltage of 125 volts AC (VAC). This means that it is designed to handle an electrical current up to 1A and a voltage up to 125VAC.

Use these micro switches to act as sensors to either limit the range of motion, detect collisions with the least amount of friction or simply as a switch.
