Reversing Key (Commutator)

Product Code : SCL-EAE-14635

Indian Lab Suppliers supplies the Reversing Key (Commutator) (Product ID: 14635) as part of its electrical and electronics range. It is a double-pole reversing key (commutator) that switches the direction of current in a circuit.

Quick Answer

A manual lever moves double-pole, double-throw (DPDT) contacts so that the two output terminals swap polarity. The contacts are brass or nickel plated on a wooden, plastic or bakelite base, with 4 or 6 screw terminals and an overall size of about 80–120 mm. Reversing the current and averaging the two readings cancels errors from the Earth’s field or zero offset.
