ABSTRACT:
A tape drive has a microswitch, with a microswitch plunger, that interacts with a tape cartridge having a recess therein that is selectively closed or opened by a sliding element movable back and forth in the recess, to detect whether the recess is opened or closed and thus to enable or disenable a data transfer function between the tape drive and the tape cartridge. To protect the plunger against breakage, and to allow changing the position of the sliding element without interference by the plunger, the tape drive has a plunger protector pivotably mounted in that is interposed between the sliding element and the plunger. The plunger protector smoothly transfers forces associated with the back and forth movement of the sliding element to forces in the direction of movement of the plunger.
