A22L-GG-6D-20M: Pushbutton Switches – Applications and Working Principles

Pushbutton switches are a commonly used type of electrical switch and one of the most versatile. Pushbutton switches come in a vast array of styles, sizes and configurations to accommodate a wide variety of applications. One of the most popular in the marketplace is the Omron A22L-GG-6D-20M. This article will explain the applications and workings of the A22L-GG-6D-20M pushbutton switch.

Types

The A22L-GG-6D-20M is a non-lighted pushbutton switch, meaning it does not include a lamp or other indicator light to indicate when the switch is pressed. It is a momentary switch, meaning the electrical connection is made only when the button is pressed and released immediately. It is also known as an “off-on-momentary” switch, meaning the button must be pressed and then released to make the connection.

Applications

The A22L-GG-6D-20M is often used in a variety of applications in industrial, scientific, medical and military settings. It is not suitable for use as a power switch, but is widely used in industrial control and automation, scientific experiments and research, medical devices, military electronics and avionics. It is commonly used to control the flow of air, water, or other liquids in laboratory settings, or to control electric motors, actuators and solenoids.

Operation

The working principle of the A22L-GG-6D-20M is fairly simple. When the button is pressed, it moves a small contact arm that is connected to an internal circuitry which closes the switch. When the button is released, the contact arm returns back to its original position and the switch is opened. The amount of electrical current that can be passed through the switch is limited by its rating. The A22L-GG-6D-20M is rated for up to 20 Amp AC/DC.

Design

The A22L-GG-6D-20M is a compact size pushbutton switch, measuring just 15mm wide and 6mm in height. It is designed to fit into tight spaces, especially on printed circuit boards, control panels, and smaller enclosures. The body is a diecast zinc alloy housing with a polyester cover. The contact arm is made from stainless steel. All components have a UL94V0 flammability rating for added safety.

Mounting and Installation

The A22L-GG-6D-20M is designed for easy installation and mounting. It is designed for both surface mounting and panel mounting. The mounting hole diameter is 12.5mm and it is designed to accept up to 3.2mm sheet thickness. It is also designed to accept standard 8-32 mounting screws.

Safety Features

The A22L-GG-6D-20M includes a number of safety features to protect users and ensure proper operation. It is designed in accordance with international safety standards including UL and CSA. The contact arm is designed to provide a positive break of the connection when the button is released. It also includes a built-in dust seal to prevent dirt and dust from entering the switch and causing interference with operation. The contacts are silver plated for improved electrical and thermal efficiency.

Conclusion

The A22L-GG-6D-20M is a versatile, high-quality pushbutton switch suitable for a wide variety of applications. It is easy to install and designed with safety in mind. It is designed for both surface and panel mounting and is rated for up to 20 Amp AC/DC. It is an ideal choice for industrial control and automation, scientific experiments and research, medical devices, as well as military electronics and avionics.
