摘要： A normally open pressure responsive electrical switch is shown having upper and lower body members with a combination terminal and disc seat member sandwiched therebetween. An electrically conductive snap acting disc is disposed on the disc seat and is adapted to snap through a centrally disposed aperture in the terminal into electrical engagement with an electrical contact disposed on a terminal mounted in the lower body member. The upper body member has a bore extending therethrough and slidably mounts a pressure converter adapted to convert pressure from a pressure source to a force and apply the force to the disc. A flexible membrane is disposed over the bore with an O-ring received on an O-ring seat adjacent the bore in the upper body member. A wall extending around the seal seat is deformed to capture the O-ring at its seat.

摘要： An accelerometer device particularly adapted for use in automotive safety air bag applications comprises an electrically insulating substrate having electrically conducting circuit paths, signal conditioning circuit components, and an accelerometer unit mounted thereon, the substrate being fixed in position on three pins within a housing. The accelerometer comprises a silicon mass movable in a silicon body relative to an integral silicon support to provide strain in the silicon body in response to acceleration and has piezoresistive sensors formed in the silicon body to be responsive to that strain to provide an electrical signal corresponding to the acceleration. A member having a selected configuration and thermal response characteristics suspends the accelerometer unit on the substrate with the piezoresistive sensors connected to the circuit paths with the piezoresistive sensors isolated from strain in the silicon body due to differences in thermal expansion between the silicon body, and the substrate during temperature changes likely to be encountered.
