The range of applications makes it suitable for a variety of control and automation tasks, such as actuator position sensing, stop control, or speed control. It can be used in motors, valves, doors, gates, pumps, elevators and other automated systems.

The switch can be used in a variety of applications including water, gas, fire safety and HVAC systems, in addition to industrial automation applications.

Working Principle

The MS118305A is a snap action, limit switch which uses a snap action mechanism to detect and limit the boundary of movement or position. This is achieved by a lever arm being connected to the moving object or actuator, and the arm is connected to the form and held in place by a spring. When the moving object crosses the boundary, the spring forces the arm, thereby activating the switch.

The switch is available in both NO (normally open) and NC (normally closed) models, both of which work on the same principle. When the moving object reaches the boundary, the spring is forced and the switch senses the movement and opens the contacts. The switch is then released and is either reset or held in the same position for future activation.
