Abstract
A mechanical limiter switch for use in a medical or surgical device has a substantially cylindrically shaped housing with a perimeter and an opening in an axial direction. The housing has a pattern along the perimeter. A spring is mounted in the opening along the axial direction, and is pre-stressed for movement in a radial direction and pre-stressed for movement in the axial direction. The spring has a radial member protruding through the pattern of the housing. A plunger is mounted in the opening along the axial direction, abutting the spring for urging the spring in the axial direction and for moving the member in the pattern along the perimeter. After a pre-determined number of activations of the plunger in the axial direction, the member will come to a terminating position and will either contact a pin to establish electrical continuity or at the terminating position break electrical continuity.

7. A mechanical switch system comprising:
-
a housing having a plurality of impediments for establishing and disconnecting an electrical connectivity of the switch; and a contact member movably associated with the impediments, wherein the position of the contact member relative to the impediments determines whether or not electrical connectivity is established, and the impediments are configured to restrict and guide movement of the contact member as it travels at least one of axially and radially relative to the impediments. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
