Snap Action, Limit Switches

A snap action limit switch, such as WBX1A12ABA, is designed with a mechanism that allows it to quickly snap open and close when pressure is applied. It is designed to turn electrical circuits on and off, providing a way to detect motion and other conditions. They are commonly used in industrial and commercial applications, such as security systems, automotive equipment, and home automation systems.

Working Principle

The working of snap action limit switches works by a mechanism that consists of three interlocking components: the actuator, the switch contacts, and the snap jumper. The actuator is the moving part of the switch that is triggered by external pressure or movement. When it receives this pressure or movement, the actuator moves a pivot-like lever, which in turn causes the switch contacts and snap jumper to move. The contact portion of the switch takes over and opens or closes, initiating the contact to break or make an electrical connection.The snap jumper, which is made up of steel or plastic, is designed to provide a fast, spring-like action and bring the connection very close to the switch guide. This allows the snap switch to work very quickly, in milliseconds, and provides reliable performance.

Application Field

Snap action limit switches are used in a variety of applications, including safety and security systems, automotive applications such as door locking and airbag systems, positioning systems, and home automation systems. These are beneficial in situations where speed and accuracy are critical.In automotive applications, snap action limit switches are used to detect the position of the vehicle\'s doors or windows. This is done with a cam or roller that follows the profile of the door or window, applying the necessary pressure on the actuator to move the switch contacts and snap jumper accordingly. This ensures that the vehicle is securely locked.In home automation systems, snap action limit switches are useful for controlling appliances, such as fans, lights, and air-conditioning units. When the appliance is moved, the sensor detects the movement and triggers the switch, which then initiates the appropriate response in the appliance. The switch can also be used to detect motion, such as a door opening or closing, which can be used to activate other devices in the home. This type of switch is also used in alarm systems, as it allows the alarm to sound quickly and accurately in the event of a potential intruder.Snap action limit switches are highly versatile, providing a range of solutions for different applications. They are reliable, accurate and cost-effective, making them an ideal choice for industrial and home applications that require fast and accurate responses.
