The Zone blasting switch from Eaton, is designed with three mechanically interlocked and lockable positions. Increase safety through a single point of control during the blasting process, and a separate deadshort position safeguarding against premature blasts. The all in one mechanical connection to short-circuit the blasting leg wires, reduces installation time therefore providing additional labour savings. A permanent galvanometer testing connection is a quick, simple and safe standard feature as opposed to the alternate methods of twisting and untwisting wires when performing short and test functions.
