ABSTRACT:
The present invention is a switch actuating unit having at least one electrical or electromechanical limiting position switch, actuatable by a mechanical sensing device. This unit structurally combines the mechanical sensing device and the electrical switches such that the switches are activated in at least two limiting positions by a common actuating plunger. The plunger extends from either side of the unit and actuates the switches upon engagement with a stop or flange plate defining each of the limit positions. Furthermore, the sensing device and switches are structurally combined so as to be moveable together.
