C. as in traffic signals illuminated with an incandescent lamp or as an anti-glare covering in front of a metering panels of automobile dashboards sometimes subject to extreme temperature elevation when the car is prolongedly parked under direct sun shine.

Abstract: A covering member of keyboard prepared by separately fixing the push button elements to a base plate instead of integral molding is disclosed in which the plate has openings arranged conforming to the pattern of the fixed contact points on the circuit board. Fixing is carried out by using a silicone rubber-based adhesive or a pressure-sensitive adhesive optionally with the aid of tailing of protrusions on the base plate into the cavity of the base of the push button elements. A method of using unit bodies carrying push button elements is alternatively used. A base plate having openings arranged in the pattern corresponding to the fixed contact points is also disclosed for use in fixing the push button elements.

Abstract: An improved pressure-sensitive resistance element is provided which is composed of an electrically non-conductive matrix of a rubbery elastomer and electrically conductive particles dispersed therethrough to have a gradient of distribution from one side to the other of the matrix. Such resistance elements can be manufactured by preliminarily mixing a fluid silicone rubber composition with the conductive particles to be uniformly dispersed therein and subsequently subjecting the mixture to curing to form a rubbery elastomer while, concurrently, the particles are naturally or by force allowed to settle to form the gradient of distribution within the matrix.The resistance elements are superior in easily obtaining the desired resistivity in a wide range by adjusting pressure applied thereto as well as a long service life, compared to products of the kind hitherto known.

When two continua are provided, the contacts are sandwiched between them. Various other modifications of the construction are proposed. The interconnectors have the advantage of dimensional accuracy and reliability in electric connection as well as easy in manufacture.
