1HS120

Snap Action, Limit Switches

The 1HS120 is a straightforward snap action, limit switch that is ideal for a range of applications. These switches are designed to control specific electrical functions and are activated by an external force applied to the operating head. The basic function of the 1HS120 is to open and close a set of contacts in response to mechanical movement of the operating head.

Working Principle

A 1HS120 switch operates on the principle of inertia. A movable contact arm is mounted to the switch body and held in place by a spring. The contact arm is made of a lightweight material that is easily moved when an external force is applied. When the operating head is moved, the contact arm is released from the spring, allowing it to move against the fixed contacts. This movement creates an electrical connection and the switch is then considered to be activated.

The 1HS120 switch includes a range of features to ensure reliable performance. These features include an adjustable operating head, a durable body, and a two-stage release mechanism. The adjustable operating head allows the switch to be set to different positions, while the two-stage release mechanism ensures that the contact arm is properly seated and not released prematurely.

Applications

The 1HS120 is suitable for a wide range of applications, including process control, automation, and machine safety. In process control applications, the switch can be used to turn off a system when it reaches a pre-determined point. In automation applications, the switch can be used to detect the position of components and enable automated movements. In machine safety applications, the switch can be used to detect abnormal conditions and shut down the system before an accident occurs.

The 1HS120 is a reliable and cost-effective solution for a wide range of applications. The switch has a simple design that makes it easy to install and maintain, and the adjustable operating head allows it to be used in different applications. In addition, the two-stage release mechanism ensures that the switch is not falsely triggered and ensures reliable performance.
