Electrical apparatus










Image Number 2 for United States Patent #3964006.

The invention relates to electrical commutation apparatus of the kind having a fixed core, a coil, a movable armature constituting a motor, a frame including shaped engaging means placed perpendicularly to the movement of the armature to support a number of housings each containing fixed and movable elements of a contact, and a shaped body member for control of said contacts. The object is to provide improvements in dimensions, avoidance of vulnerability to dirt, and adequate rigidity without undue bulk. These are obtained in that the frame and the control member are each constituted by at least one portion of a prismatic body cut longitudinally and in that the shaped body comprises at least the engaging means for the housings and the surfaces for guiding movements of the armature.
