A pushbutton switch is an electrical switch activated by pressing a button, commonly used to control devices such as lighting fixtures, doorbells, and alarms. Based on material, they can be categorized into standard pushbutton switches ，metal pushbutton switches and Straight Key Switch.

Standard pushbutton switches are primarily classified by size: 5.8*5.8 key switches, 7*7 key switches, 8*8 key switches, and 8.5*8.5 key switches. By structure, they are divided into latching switches and non-latching switches.

Metal pushbutton switches can be categorized as momentary (the switch returns to its original position when the button is released) or latching (the switch remains activated until manually reset). Available in diverse sizes, shapes, and configurations, pushbutton switches are widely used in both residential and industrial applications.

The Straight Key Switch is a mechanical switch that controls circuit connection and disconnection through a linear pressing action. Its operating direction is parallel to the switch axis, featuring a simple structure, intuitive operation, and high durability. It is widely used in electronic devices requiring clear mechanical feedback.
