AH71517559-A

Snap Action, Limit Switches

The AH71517559-A is an omnidirectional snap action, limit switch that reliably switches states when it is exposed to excessive force, or some form of pressure. This force or pressure is then transferred and translates into a low voltage electrical signal that is sent back to the switch, thus activating the switch and reflecting either an open or closed status via two electrical contacts.

This type of switch is ideal for applications where it may be important to recognize a single actuation, and also for applications where resetting the switch is difficult or inconvenient. It also provides many advantages over other similar mechanical switches, such as lower installation cost, higher durability, higher reliability, and simplified maintenance.

Application Field

AH71517559-A is often used in many industrial, commercial, and residential applications, such as automotive, commercial lighting, security, industrial and process control, food processing, and even medical and pharmaceutical equipment.

With this type of snap action, limit switch, one can detect irregularity in production processes or detect when an object, such as a door sensor, is opened or closed or some other type of abrupt change occurs.

How it works

The AH71517559-A switch is designed to respond reliably to pressure or force that is applied to it. Pressure or force is applied to a mechanical lever, which then triggers the switch and causes it to open or close. The lever is typically spring-loaded to ensure reliable operation upon exposure to a force greater than that provided by the spring.

When the lever is opened, the switch will typically open, or the contacts may be open, closed or bridge-closed depending on the switch configuration. When the lever is closed, the switch will typically close. Immediately, the switch contacts act to transfer an electrical signal that is sent back to the switch and corresponding to the open or closed state of the switch contacts.

Conclusion

The AH71517559-A is an omnidirectional snap action, limit switch. Its design provides multiple advantages over other similar mechanical switches, and it is primarily used in applications where it may be important to recognize a single actuation and for applications where resetting the switch is not practical. Its operation is based on the application of additional force or pressure, which is then transferred and converted into an electrical signal that corresponds to either an open or closed state of the switch.
