2117897 9322781 PCTABS00028 A pressure switch (30) adapted to be placed within a pressurized chamber for generating a logical signal when the pressure within the chamber reduces to a determinable pressure P1. The pressure switch (30) comprises: a pressure vessel (32) sealed at one end (34) by a snap action diaphragm (40) and having an inner stop (42) and an outer stop (60, 62) respectively positioned on opposing sides of the diaphragm (40) for limiting diaphragm motion. The outer stop comprises: a first cylindrical portion (78), a first pair of parallel slots (80a, b) formed therein and a through bore (70, 72, 74) extending therethrough. A switch assembly is loosely mounted to the outer stop. The switch assembly (90) comprises an upper housing member (92), a lower housing member (94), first and second electrical contacts (96a, 96b) and a pin (98). The upper housing member (92) comprising a hollow cylindrical portion (100) adapted to be slid over first cylindrical portion including a second pair of opposing slots (113a, b), the first and second cylindrical portions (78, 100) are loosely secured together by a clip (150) fitted within the first and second pair of slots (80a, b; 112a, b) to eliminate compressive loading between the switch assembly and other components of the switch.
