AH71505559-A

Snap Action, Limit Switches

AH71505559-A is a type of mechanical component that are used to activate or control a circuit using an assembling of contacts (or "conductors"). They are typically used in many industrial control and automation applications, such as controlling the acceleration and deceleration of a motor, which is why they\'re often referred to as motor control switches.

The AH71505559-A snap action switch consists of a cylindrical body with the contacts arranged around the circumference of the body. The contacts of the switch are held in position by springs and mechanical locking mechanisms, making them more reliable and durable for operating in harsh industrial environments. The contacts are released by a snap action mechanism triggered by an external force, such as a push rod or lever.

These switches also feature a steel housing with either zinc or a special black finish, providing a high level of protection against dust and moisture penetration. Additionally, the switches are designed with a special mechanism that creates an audible click when the contacts move, making it easy to identify the exact moment when the contacts are operated.

The working principle of AH71505559-A snap action switch is based on the principle of a spring-loaded contact arm. When an external force pushes against the contacts of the switch, the contact points open and close as the force is transferred to the contact arm. The contact arm is then connected to a mechanical locking mechanism that keeps the contacts in position until the external force is removed. When the external force is removed, the contact arm is released back to its normal position, closing the contacts again. This keeps the switch in an open state while the external force is not applied.

This snap action switch is designed to provide reliable electrical switch control and reduce the need for manual intervention. It is an ideal choice for applications requiring high speed switching and detecting long lasting open states. The switch is available in a variety of sizes and switch configurations, such as wide-range power, thermoplastic dielectric, UL listed and cRUus approved. Additionally, the switch has a temperature range of -45°C to +85°C and a maximum voltage rating of 250V AC/DC.

The AH71505559-A snap action switch is a cost-effective and reliable solution for most industrial control and automation applications. It is designed to provide reliable and accurate operation even in harsh industrial environments, and is available in a variety of sizes and configurations to suit a wide range of applications. Additionally, it is designed with a special mechanism that emits an audible click when the contacts move, making it easy to identify the exact moment when the contacts are operated.
