摘要: A casing for switches for industrial machine or plant control comprises a containment shell (2) having at least one opening (4) made on its front face (5) for accessing thereinside and having an outer perimeter edge (8), a lid (6) anchored in a movable manner to the front face (5) and having a perimeter edge (7) adapted to at least partially overlap the outer perimeter edge (8). The lid (6) has on its inner face a groove (9) which extends along the whole perimeter edge (7) thereof, internally thereto and which has a gasket (10). The front face (5) has a raised sealing edge (11) which extends internally to the outer perimeter edge (8) and along the whole longitudinal extension of said outer perimeter edge (8), said raised sealing edge (11) having a profile corresponding to that of said groove (9).

摘要: Provided are a sensor and electronic device that enable reductions in the sealing performance of a sealant to be minimized. The sensor 10 comprises a setting part 18 which changes settings of a main sensor unit, and an annular seal ring 60, which is disposed so as to encircle a shaft 18b of the setting part 18, and seals a gap between the shaft 18b and a housing 12. The seal ring 60 comprises a curved surface section 61 which curves outward as seen in cross section, and a pair of end sections 62a, 62b, on both sides of the curved surface section 61 in the axial direction of the seal ring 60, which have a different shape from the curved surface section 61 and extend in the axial direction of the seal ring 60.

摘要: A snap-action switch including: a housing in which a plurality of fixed contacts and a plurality of movable contacts are disposed therein, a plunger configured for depressible movement via an aperture in the housing from a first position in which the plunger is relatively extended outwardly of the housing via the aperture, into, a second position in which the plunger is relatively retracted inwardly of the housing via the aperture; and a snap-action assembly operably-connected with the plunger, said snap-action assembly being responsive to depressible movement of the plunger so as to effect snap-action type movement of the plurality of movable contacts between normally opened and normally closed positions with respect to the fixed contacts; a sealing element configured for arrangement around the plunger to occlude ingress of particulates, dust and water from entering the housing via the aperture, said sealing element including a flanged portion; and a securement element configured for arrangement around the sealing element, wherein said securement element is shaped and dimensioned for interference fitting or snap-fitting with a rim of the aperture whereby the flanged portion of the sealing element is secured between the securement element and the rim of the aperture so as to restrict removal of the sealing element from the housing.
