Abstract:
An actuator assembly for operating a device in a normally open mode and a normally closed mode, said actuator assembly comprising:a frame extending between a first ridge and a second ridge; a primary plate adapted to be secured to one of said first ridge and said second ridge, said primary plate including a primary hole; a secondary plate adapted to be secured to the other of said first and second ridges, said secondary plate including a secondary hole; a bobbin defining a longitudinal axis and extending between said primary and secondary plates; a coil wrapped around said bobbin, said coil receiving an electrical current to induce a magnetic field thereabout; a rod extending along said longitudinal axis from within said frame to the device, said rod movable along said longitudinal axis in response to said magnetic flux to open and close the device; and a plunger extending through a portion of said bobbin and movable with respect thereto in response to changes in said magnetic field, said plunger including a rod receptacle for fixedly securing said rod therein allowing said rod to move with said plunger, said plunger further including an opposing rod receptacle disposed across said plunger from said rod receptacle such that said plunger is adapted to be oriented in a first orientation allowing said actuator assembly to operate the device in the normally open mode and a second orientation allowing said actuator assembly to operate the device in the normally closed mode, wherein said opposing rod receptacle fixedly securing said rod therein when said actuator assembly is operating the device in the normally closed mode.
