<p>The invention concerns a powered control (10) with three terminals, wherein the current flowing through the first half-coil rotates the rotor in a first direction, and the current flowing through the second half-coil rotates the rotor in a second direction. The rotation of the rotor in the first direction causes the mechanical linkage (16) to move the circuit breaker handle (18) to its on position. The rotation of the rotor in the second direction causes the mechanical linkage (16) to move the handle to its off or reset position. When the on button (22) is pressed, an electric current is made to flow through the first half-coil until the circuit is opened by the end-of-stroke contact. When the off button (24) is pressed, an electric current is made to flow through the second half-coil until the circuit is opened by the end-of-stroke contact.</p> |
