Abstract

Electric pushbutton and membrane switch, essentially characterized in that the bridge-shaped electroconductive element, intended to be supported simultaneously, during the closing periods of the circuit, on the lugs integral with the fixed contacts, has an annular shunt on one of its faces, destined to remain inside the head of a helical spring, arranged coaxially and housed in a central cavity of the electro-insulating base of the device, while the other face of the bridge piece remains internal and in contact with an elastic membrane in the shape of plate, supported by its edges between the upper ones of the base and a lateral enclosure of section in the form of c, that extends superiorly in a cylindrical body, threaded externally in order to its fixation and or provided, of an axial conduit destined to the guided of the squeezing rod for the moving part of the apparatus, said shank extending in a smaller diameter lug which it carried in its extremely a protruding annular element, conjugated with a similarly annular recess of a tubular sleeve whose end, provided with a flange, rests directly on the convex side of the membrane and is in turn internal to an opposing spring of helical configuration, inside to a central cavity of the enclosure and whose head acts by means of a crown washer, on the push rod.
