Snap Action, Limit Switches

Snap action, limit switches are an essential component in all types of devices, and the WLGCA12 is a great example of a reliable, accurate, and versatile switch. This article will provide an overview of the WLGCA12\'s application field and working principle.

Application

The WLGCA12 has a wide range of possible applications and is particularly well-suited for use in the automotive, medical, consumer electronics, and industrial sectors. It is a robust switch, with a long service life, so it can be used in a variety of applications requiring reliable performance. It is widely used as a limit switch, to detect the end of travel on mechanical components, or to detect the presence of an object. It is also often used as a snap action switch, in applications such as door locks, or as a brake release switch. Additionally, the switch is suitable for use in safety circuit designs, where accurate and reliable operation is essential.

Working Principle

At the heart of the WLGCA12 switch is a snap-action contact mechanism. When manual or mechanical force is applied to the Load Spacer, a plunger is pushed in, which causes the contacts to move and make or break the switch connection. The plunger has a pre-set resistance, so the force required to activate the switch is consistent. The amount of force required can be adjusted by turning the Variable Resistor located at the top of the switch.The switch also features an adjustable operating temperature range of -40°C to 85°C, which can be adjusted by setting the Adjustable Thermistor. This allows the switch to handle temperatures beyond its standard range, so it can be used in extreme environments.The switch is also designed to be vibration-resistant, with a maximum frequency of 100Hz. This makes it ideal for use in high-vibration applications, such as in automotive engines. Additionally, the waterproof design ensures reliable operation in wet environments.

Conclusion

In conclusion, the WLGCA12 switch is a robust and reliable component, which can be used in a variety of applications requiring reliable performance. Its snap-action contact mechanism provides consistent force and operation, while the adjustable operating temperature range and vibration-resistant design make it ideal for use in extreme environments. Therefore, it is no surprise that the WLGCA12 is a popular choice for use in the automotive, medical, consumer electronics, and industrial sectors.
