In electronic circuits, unlatching push-button switches are widely used due to their ability to operate without requiring high current. As a result, they typically feature compact designs and small sizes, often referred to as tactile buttons or microswitches. Examples of unlatching push-button switches include mouse buttons and mobile phone keypads. Modern electronic devices and instrumentation systems generally incorporate human-machine interaction features, where tactile buttons serve as one of the primary components in user-friendly input devices. The system can respond appropriately based on user interactions with these tactile buttons, interpreting information such as the current system state at the moment of contact, the number of presses, the duration of each press, and which specific button has been activated.
In the evolution of human-machine interaction interfaces, a technology known as membrane keypads has gradually replaced tactile buttons in many applications. Membrane keypads allow multiple metal contacts to be embedded into a thin film panel composed of several layers, tailored to meet specific user requirements. These contacts are connected via printed metallic traces and linked externally through FPC (flexible printed circuit) connectors, enabling seamless integration with external terminals. Membrane keypads offer a delicate tactile feel and support simultaneous multi-key functionality, enhancing both aesthetic appeal and simplifying the overall mechanical design of devices. Additionally, they provide a degree of water resistance, making them highly favored by many users. However, due to their custom-made nature, membrane keypads involve complex manufacturing processes, resulting in relatively high production costs. Furthermore, the mechanical contacts within these keypads have inherent limitations in terms of durability and lifespan, which somewhat restricts their widespread adoption in certain applications.
