Abstract

A quarter turn latch (10) includes a latching member (12) connecting to an actuating member (14). The latching member (12) and actuating member (14) snap together from opposite sides of a mounting surface member (100). The latching member (12) includes a cam member (20) for engaging the complimentary latch member (102) to retain it against the mounting surface member (100). The mounting surface has a depressed portion (16) with an orifice (18) formed therein. The orifice has opposed straight sides (70) and rounded end portions (72). The actuating member includes a barrel shaped body (24) having opposed rounded larger radius corner portions (32) and opposed squared corner portions (34). The actuating member provides for rotation along the rounded portions (32) against the end portion (72) and straight side (70) while the squared portions (34) engage the straight side portion (70) to limit rotation to one quarter turn.
