Snap Action, Limit Switches

831613C3.GB is a kind of snap action, limit switches with distinctive features.They are specifically designed to be used in place of mercury wetted relays and stabilize limit switches, because of their highly reliable operation and extended life.

Application Field

831613C3.GB snap action, limit switches have been widely applied to many areas including industry, auto, electronics, machine and apparatus, etc.For industry area, they can be widely used in fan and pump motors, vending machines, machine tools, lifting machinery, machinery start and stop devices and conveyers.For auto area, 831613C3.GB is often used for wiper motor control, windscreen washer, sun roof open and close, shift lever control, etc. For electronic field, these limit switches are a typical solution for moving parts switch control like gaming machines, money detectors and X-ray machines.

Working Principle

The functioning principle of these snap action, limit switches is based on their innovative contact structure and actuator design. The contact structure consists of a stationary contact arm, resiliently biased toward a contact, both of which are attached to insulating support material. When the actuator moves to the closed position, the movable contact member makes contact with the contact arm, forming the fully closed circuit. At the open position, the contact arm is held away from the contact. Furthermore, the actuator further includes an adjusting screw, a resilient contact arm, a movable contact, a contact arm and an actuator connection arm, providing more accurate, reliable and repeatable performance.

Advantages

Compared to traditional mercury wetted relays or other general limit switches, 831613C3.GB has some of the following differences which contribute to its wide range of applications:

• Highly reliable operation and extended life span
• Wide operating temperature range
• High-precision switching position
• Highly accurate switch in both open and closed positions
• Heavy current switching capability
• High EMC resistance
• Highly vibration and shock-resistant
• Compact, robust design
• Operation and maintenance-free
• Low cost and easy installation

Conclusion

As a kind of snap action, limit switches, 831613C3.GB is becoming more and more popular for its reliable operation and extended life, as well as its wide range of applications. The innovative contact structure and actuator design not only provide more accurate and reliable performances, but also eliminate the need for frequent maintenance.
