Plug Key

Product Code : ILS-PLE-10189

Indian Lab Suppliers supplies the Plug Key (Product ID: 10189) as part of its physics lab equipment range. It is a one-way plug key that closes a circuit when its tapered plug is pushed in and opens it when the plug is pulled out.

Quick Answer

An accurately tapered plug with a moulded bakelite top fits into the gap between two brass blocks, each 9 mm thick. With the plug in place the blocks are joined and current flows; removing it breaks the circuit at a clearly visible gap. Brass terminals on the blocks take the circuit leads, and the key is mounted on a bakelite base.
