Snap action and limit switches help regulate the operation of mechanical devices and systems, providing automation and operator protection. The AH755179-A is a snap action and limit switch designed for manual operation and features a Lever Actuator. It is used in applications ranging from motor controls, machine tool operations and industrial motor feedbacks.

The AH755179-A comprises an SPDT (single pole double throw) switch with a lever actuator, which is designed to be mounted in any direction, including mounting to side-mounting panels. It also features an adjustable positive force and snap action. The snap action rotates the contacts on and off, with a resulting travel of 2 millimetres. The travel distance can be adjusted between 0.3 - 2 mm and the release force can be set from 0.3 to 1.5N. The contacts are predefined and feature M3.5 serrated terminals. The contact material is gold with a maximum rated current of 10 Amps.

The AH755179-A is activated when an external object is applied to the lever arm. The actuator lever rotates about the axis onto one of the two contacts, creating an electrical circuit thereby closing the switch. When the pressure on the external object is released from the lever arm, the actuator lever rotates back to the original position and the switch remains OFF. The AH755179-A is supplied with a mounting plate and screws.

The AH755179-A is designed to provide reliable operation under harsh environmental conditions. It features a robust and durable construction, with a heavy-duty body and lever arm made of die-cast zinc. The switch is also protected from the ingress of dust and water by its IP65 environmental protection rating. Furthermore, the switch is climate-resistant (pry-resistant, antistatic, corrosion-resistant) and operates from -20 to +70 °C.

In conclusion, the AH755179-A is highly reliable and suitable for a range of applications. Its design makes it easy to install and configure, while its robust construction ensures reliable operation in harsh environments. The AH755179-A can be used to detect a range of positions and movements, providing automation and protection for motor controls, machine tools and industrial motor feedbacks.
