Snap action, limit switches are a type of electrical switching device designed to detect the physical movement of an operating device, such as the opening or closing of a door or valve, and actuate other control devices, such as a relay, when certain predetermined conditions are triggered. AH71537559-A is one such switch that offers numerous advantages in industrial and commercial applications.

Description

The AH71537559-A snap action, limit switch is a multi-pole device, with a wide voltage rating of between 12 and 250 volts and a current rating of between 1 and 8 amperes. It has an adjustable snap action and a gold plated contact surface which offers increased resistance to wear and tear. This device is designed to have superior reliability, flexibility, and durability compared to other snap action switches.

Application Field

The AH71537559-A is suitable for use in a wide range of applications, including, but not limited to, heavy duty industrial on/off switching, switching of loads requiring rapid response or higher activation force, and applications involving extreme temperatures, vibrations or continuous operations. It is also suitable for use in controlling the movement of mechanisms in safety critical or hazardous areas.

This switch is often chosen for its superior performance and reliability in applications including solenoids, furnaces, and hoists. It can also be used in industrial automation, conveyors, and process control systems. This switch is also suitable for use in medical and health care applications such as diagnostic and therapeutic equipment, medical imaging systems, and in medical devices requiring an on/off switch.

Working Principle

The AH71537559-A snap action, limit switch works according to the principle of mechanical actuation. A spring-loaded actuator is connected to a contact surface which consists of a pair of gold-plated contacts. When a physically operated device, such as a door or valve, is opened or closed, the actuator is pushed in or pulled out, causing the contacts to close or open, respectively.

When the contacts close, an electrical signal is sent to a control circuit, triggering a relay or other control device, which can then be used to switch an electrical load on or off. In some cases, this switch can be used in conjunction with a limit switch, which will limit the range of motion the actuator is capable of, providing additional safety and accuracy.
