About This Product
A plug key is a simple switch that closes a circuit when its brass plug is pushed between two brass blocks and opens it when the plug is removed. In school physics it is used in circuits for Ohm's law, the metre bridge and the potentiometer, to make or break the current. Keys with more ways give more than one gap for connections. School Lab Equipment India supplies the Plug Key across India and can export it to Cyprus, Kazakhstan, South Africa, Egypt and Botswana.
