Tapping Key

Product Code : SCL-EAE-14634

Indian Lab Suppliers supplies the Tapping Key (Product ID: 14634) as part of its electrical and electronics range. It is a single-pole, press-to-make key that closes a circuit only while it is held down.

Quick Answer

A springy brass or nickel-plated contact blade meets a lower contact when pressed and springs back when released, so current flows only for as long as needed. It is mounted on a bakelite, plastic or wooden base with brass or nickel-plated screw terminals and measures 60–90 mm depending on model. Short, momentary contact keeps resistors and cells from heating during readings.
