ABSTRACT:
A rotatable latch, as for the door of an enclosure, has a positive indication of latching, the indication capable of being felt and heard. A rotatable latch member mounted, for example, on the door, has a radially extending finger which engages with a latch plate mounted on the door frame. The latch plate has an inclined surface up which moves the finger, against a spring bias. At the end of the inclined surface is a detent into which the finger snaps, under the action of the spring bias, when the rotatable latch member is in a fully latched position. The snapping of the finger into the detent can be both felt and heard.
