Switch ICs (Integrated Circuits) are semiconductor devices designed to control, route, or select electrical signals within electronic circuits. They function as electronic switches, allowing signals or power to be turned on/off or directed between different paths without requiring mechanical components.

Switch ICs are commonly used in signal routing, multiplexing, power management, audio/video systems, communication equipment, industrial electronics, and consumer devices.
