| 摘要 | A mechanical limiter switch(10,110) for use in a medical or surgical device has a substantially cylindrically shaped housing (12) with a perimeter (12a,12b) and an opening (14) in an axial direction. The housing has a pattern (16, 16a,16b) along the perimeter. A spring (20) 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 (22) protruding through the pattern of the housing. A plunger (30) is mounted in the opening along the axial direction, abuts the spring for urging the spring in the axial direction and moves the radial member in the pattern along the perimeter. After a pre-determined number of activations of the plunger in the axial direction, the radial member will either establish electrical continuity with a contact pin (40) or break electrical continuity of the radial member with the housing metal portion (12b) at the terminating position. | ||||||
