Product Description
The Contact Key is a fundamental switching device used in electrical circuits to manually open or close the flow of current. Commonly used in physics laboratories for demonstration and experimentation with circuits, it enables controlled activation of current for brief or sustained durations. Made from durable, conductive metals with insulating bases, Contact Keys are essential components in circuit testing, timing devices, and low-voltage experimental setups.
