Switches are electromechanical components used to intentionally make, break, or change an electrical connection within a circuit. They provide a controlled interface for directing current flow by transitioning between defined electrical states.

Within the electromechanical category, switches generally include devices that:

• Open or close a circuit path
• Select between multiple circuit paths
• Enable or disable electrical functions through mechanical actuation

Switches are commonly categorized by their operating method and contact arrangement, and are selected based on the required switching behavior and integration needs within an electrical or electronic system.
