Pushbutton switches are one of the most basic and wide-ranging of all the kinds of switching elements. Seeing their pervasive use in electronics and appliances, it’s important to understand exactly how they work. An A22L-TR-12A-10A switch is a particularly common type of pushbutton switch, used for several purposes that require the simple on/off action that pushbutton switches are capable of.

Applications of A22L-TR-12A-10A Switches

A22L-TR-12A-10A switches are used in a wide variety of devices and applications. These switches are small, cost effective and capable of fitting into small spaces. This combination makes them a great choice for many kinds of products. Here are some of their most common applications:

• Control panels and consoles, used in industrial and laboratory settings
• Manual reset of electronics, such as gaming consoles, computers and even some consumer appliances
• Security systems, particularly those with keyed locks
• Switches activated by hand, as found in emergency call systems and electrified doorbells
• Portable medical equipment, such as wheelchairs and infant incubators
• Lighting and temperature control, in residential and commercial environments
• Retail kiosks, used for product selection and checkout

What is the Working Principle of A22L-TR-12A-10A Switch?

The A22L-TR-12A switch makes use of two basic components: a surface mount membrane switch and a specialized actuator. The components work together to enable users to manually toggle an electrical switch on and off while limiting the size of the switch and keeping it safe and secure.

The A22L-TR-12A membrane switch consists of three basic layers: a substrate, a dielectric layer, and an exposed contact layer. The dielectric layer is sandwiched between two layers of the substrate, which ensures that diffusion currents will not occur during operation. The substrate also acts as an insulator and prevents short circuits. The exposed contact layer consists of two interconnects, one of which is attached to the actuator.

The actuator is then used to complete the circuit. It consists of a conductive spring, a rigid spring arm and an anchored base. When the actuator is compressed, the conductive spring is brought into contact with the exposed contact layer, and the electrical circuit is completed. This pressure to the actuator is what allows the user to toggle the switch, providing an ‘on’ or ‘off’ action.

Conclusion

The A22L-TR-12A-10A switch is a common and versatile tool, used in many different applications. Its simplicity makes it easy to install and use, while its rugged design makes it safe and reliable. In situations that require the manual activation of an electrical switch, the A22L-TR-12A-10A is a dependable and cost-effective solution.
