About Slide Switches

What is a Slide Switch?  (滑动开关/拨动开关)
A slide switch is a mechanical device that is commonly used for controlling an electrical circuit. It utilizes a simple sliding action to move the switch from an open position to a closed one, or vice-versa. As maintained-contact switches, slide switches remain in one state until manually actuated into another state.

Common Slide Switch Configurations
Slide switches will often have a single pole, double throw (SPDT) construction. This allows the power being delivered to the circuit to be swapped from one power source to another (referred to as on-on operation). In other words, the movement of the slide switch actuator redirects the flow of current from one circuit to the other.

Single pole, single throw (SPST) slides switches are also commonplace, providing on-off functionality. Under certain circumstances, a double pole, double throw (DPDT) circuit might be required, allowing for on-off-on configurations. 

Slide switches are also defined in terms of their size with the most common slide switch categories being subminiature, miniature, and standard. 

Slide Switch Applications and Considerations
Slide switches can be used in domestic, office, and industrial settings ranging from computer peripherals, household appliances, consumer electronics devices, smart home systems, test equipment, communication hardware, and numerous other items.

Conclusion
Slide switches are well-recognized, basic mechanical switches that provide simple functionality, most often when switching between one state or another is required. They offer the visual benefit to the user of knowing exactly which state the switch is operating in as well as consistent and maintained control of the switching mechanism. With a simple understanding of their typical configurations, key specifications, and design considerations, engineers can select the appropriate slide switch for their design.
