About This Product
A reversing key, or commutator, switches the direction of current through part of a circuit without rewiring it. In school physics it is used in electrical experiments with a galvanometer or a potentiometer, where the current or connections must be reversed to repeat a reading. Moving the handle shifts the contacts from one segment to the other. Alongside supply within India, the Reversing Key is offered for export to Guinea-Bissau, Kiribati, Malaysia, Bahrain, Qatar and Rwanda.
