Contact Key, Single

The Contact Key, Single is a straightforward mechanical switching accessory for controlling electrical connections during physics and laboratory circuit experiments. It provides a convenient method of opening and closing a circuit manually, allowing students to observe the effect of interrupting or completing the current path.

The assembly incorporates a spring arm, press knob and contact stud, along with a connecting strip that provides the electrical connection between the contact points. Two 4 mm terminals are included for connecting compatible laboratory leads, making the unit suitable for use with standard physics experiment setups.

The complete contact mechanism is mounted on a plastic base measuring 110 × 50 mm. This compact base provides a stable platform during practical demonstrations while keeping the operating mechanism easily accessible. The press knob allows the user to operate the spring arm and establish or interrupt contact as required by the experiment.

This single contact key can be used in demonstrations involving simple electrical circuits, current flow, circuit continuity, switches and basic electricity principles. It is particularly useful in school and college physics laboratories where students need to understand the practical operation of a circuit control device.

The mechanical construction offers a simple alternative to more complex switching arrangements. Because the contact action is directly visible, instructors can demonstrate the relationship between circuit continuity and electrical current in an easy-to-understand manner.

The 4 mm terminal arrangement also makes the contact key convenient to integrate with compatible laboratory wires and electrical experiment apparatus. Its small footprint allows it to be used individually or alongside other components on a laboratory workbench.

Micro Technologies supplies this Contact Key, Single for educational laboratory equipment requirements and institutional procurement. With proper handling and periodic inspection of the contact surfaces, it can serve as a reusable component for repeated practical sessions.
