Description
The Key Press Contact Switch, Silver-Plated Contact Points, Silver Plated Points, also known as a press switch or classroom circuit contact key, is designed for supervised basic electricity experiments where a circuit needs to be made or broken manually. This IEC contact key operates by closing the circuit only when the key is pressed down, making it suitable for demonstrations involving current flow, simple switching, timing activities and basic circuit control. The electrical connections are made through IEC 4 mm socket spin-free head terminals as listed, supporting connection with compatible laboratory leads and low-voltage circuit accessories.
The contact points are silver plated as listed, while the spring blade is made from strong phosphor bronze, supporting reliable repeated use in classroom laboratory environments. This contact key is useful for school science laboratories, university teaching laboratories and physics classrooms requiring a simple manual switch for student practical work. Users should confirm circuit voltage, current limit, lead compatibility, terminal condition and experiment method before use. Do not connect this contact key directly to mains electricity or unsuitable power supplies. Use only in compatible low-voltage educational circuits.
Avoid short circuits, overloaded circuits, loose leads and damaged terminals. Disconnect the circuit before adjustment, cleaning or storage. This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the press type contact key only. Leads, power supply, bulbs, resistors, meters, circuit boards, worksheets and additional electrical accessories are not included unless specified separately.
LabChoice Australia supplies Contact Keys and electrical circuit teaching equipment for school science laboratories, university teaching laboratories and educational facilities requiring practical tools for electricity and circuit demonstrations.
