Eduscope India is a leading Plug Keys
Plug Keys are a fundamental component used in physics laboratories to control the flow of electric current within a circuit, part of EduScope India's Physics Lab Equipment range. Quick Answer: Plug Keys are brass-and-Bakelite circuit switches that let students activate or interrupt current flow with a simple tapered-plug mechanism - reliable laboratory equipment school India physics departments use for current-electricity experiments.
Construction and Materials
The Plug Key is built with two brass blocks fitted with brass terminals, mounted securely on a Bakelite base. An accurately tapered plug, molded with a Bakelite top, is fitted into the hole located between the two brass blocks. This combination of brass and Bakelite ensures dependable electrical conductivity along with a sturdy, insulated housing suited for regular laboratory use.
Function and Operation in a Circuit
The plug key allows for easy activation or interruption of current flow within a circuit. When the tapered plug is inserted between the brass blocks, the circuit is completed and current flows through the connected components. Pressing or releasing the small metallic key turns the circuit on or off, allowing students to observe circuit behavior in real time. This straightforward on/off mechanism makes the plug key useful across a wide range of physics experiments involving current electricity.
