More Information
Summary:The invention is directed to a switch assembly which can be used in situation in which the switch accommodates the flow of high voltage current. An actuator assembly with moveable contacts is moved by a motor driven armature. The moveable contacts are in electrical engagement with the stationary contacts when the armature is in the first position, and the moveable contacts are spaced from the stationary contacts when the armature is in the second position. By angling the stationary contacts and moveable contacts, the linear motion of the armature causes the moveable contacts to move across the surface of the stationary contacts as the armature approaches the first position. As all of the movements of the assembly are in a direction parallel to the axis of the armature, the assembly can be manufactured and operated reliably in a relatively small space. In addition, the linear movement on the angled contact provides for a positive electrical connection even in adverse environments.
