Introduction to Pushbutton Switches

Pushbutton switches, also known as momentary contact buttons, are often used as a user interface in a wide range of electronic devices. They are designed to be pressed and released quickly to trigger a signal or action. Pushbutton switches come in a variety of sizes, shapes, colors, and contact arrangements. The most common type is the single-pole single-throw (SPST) switch, which just has two contacts (one normally open, one normally closed).

AB25AH-HA Application Field and Working Principle

The AB25AH-HA is a small, yet durable, pushbutton switch that can be used in a variety of applications. It is a 2-pole, 2-throw (2P2T) switch, meaning it has two sets of contacts – one normally open (NO) and one normally closed (NC). This makes it ideal for use in applications that require a momentary toggle, such as resetting devices, switch-mode topologies, or mechanical latching.In terms of operation, the AB25AH-HA Pushbutton Switch features break-before-make contact action meaning that when the actuator (button) is pushed, the contacts will break before they make. This prevents any short circuits or potential damage to the switch or connectedcircuitry. It also has an extended mechanical life rating of up to 5 million operations, ensuring its longevity and dependability.In addition, the AB25AH-HA Pushbutton is rated for a maximum current of 5A, can handle voltages up to 250V AC and has an operating temperature range of -40°C to +85°C. Its rugged construction and 18mm diameter diameter actuator make it particularly useful in environments where it will be subject to frequent use or impact.

Conclusion

The AB25AH-HA Pushbutton Switch is a dependable and versatile switch that is more than capable of withstanding the rigors of both commercial and industrial applications. With its break-before-make contact action and extended mechanical life rating, the AB25AH-HA is an ideal solution for resetting devices, switch-mode topologies, and any situation that requires a momentary toggle.
