12HR11-R1

Snap Action

Snap action, also known as limit switches, are electromechanical devices that use a mechanical mechanism to open or close an electrical contact when a specified travel distance is reached. These switches are most commonly used to control automatic activation or deactivation of a system, such as a robotic arm or a conveyor belt. 12HR11-R1 is a type of limit switch from Japanese manufacturers Hirose Electric, designed for thin and compact applications, particularly mobile and handheld products. The switch has a very small form factor and low profile, making it perfect for embedding into thin walls or spaces.

Working Principle

The 12HR11-R1 switch uses a snap-action lever, which responds to the force applied during switching by quickly jumping from open to close (or vice versa). The switch is operated by a small applied force, and the internal mechanism ensures that the contacts will open or close reliably when the force is applied. The switch is also equipped with a small plunger that is actuated by the lever, providing a visual indication of the switch position. The switch is designed to be operated from either direction, allowing for versatility in applications.

Application Field

The 12HR11-R1 switch is widely used in a variety of applications, due to its small size and low profile. The switch is often utilized in the automotive, aerospace, and consumer electronics industries, as it is capable of withstanding harsh environmental conditions. Additionally, the switch can be used in a variety of industrial applications, such as sensing the position of doors, controlling automated machinery, and regulating the flow of liquids. The switch can also be used in applications such as home automations, enabling the switching of electrical appliances, such as lights, fans, and other electronic devices.
