Abstract: A compulsory switch activating latch for being fixed to the casing of a cash drawer. The latch includes a pivotable latch member for engaging a latch bar on the drawer. The pivotable latch member is also capable of limited reciprocal movement in the direction of movement of the drawer in and out of the casing. A spring between the drawer and casing urges the drawer, latch bar and pivotable latch member in the outward direction of the drawer when the latch bar is locked in the pivotable latch member. A detector is provided for detecting such movement of the movable latch member, whereby the locked condition of the pivotable latch member is detected with certainty. In the preferred embodiment, the detector includes a slidable switch member in contact with the lever of a lever microswitch, and is positioned so as to be moved by the pivotable latch member to close the microswitch when the pivotable latch member is moved outward by the spring between the drawer and casing.
