摘要： An electrical switch is provided with a switch operator having a resilient pad on its distal end, the operator being mounted for axial movement in an operator housing to actuate contacts deposited in a double spiral pattern on a substrate coupled to the operator housing. The operator tip is moved first to contact the front side of a flexible membrane which is separated from the contacts by a spacer. The operator pad is then moved further to deflect the membrane and close the gap formed between the shorting patch and the switch contacts, the travel of the operator and the action of the pad providing a sensation of feel to the user. The switch is constructed in single units and in arrays.

摘要： An assembly for connecting a tubular conduit to an apertured wall of a non-metallic enclosure including a tubular insert seated in the aperture and a threaded, rotatable, hollow hub member arranged to be received by an externally projecting portion of the tubular insert. The closed end of the hub member adjacent the enclosure rests against a compressible resilient ring for sealing engagement and being further adopted for rotatable engagement with respect to the enclosure by means of an interposed washer made of a material having relatively low coefficient of friction with respect to the hub member. The components of the assembly are held together by means of a laterally extending lip formed at the distal end of the insert after assembly of the cooperating elements to the enclosure.
