摘要： An electromagnetic relay and a circuit substrate comprising the same are disclosed, for preventing erroneous operation when they are wet by water, at low cost. The electromagnetic relay comprises a case having fluid-tight characteristics; an excitation coil provided in the case; and electrodes connected to both ends of the excitation coil in a manner such that at least a portion of each electrodes is formed outside the case and is exposed to an area where a liquid can penetrate.

摘要： An improvement in an electromagnetic switch matrix permits the simultaneous closing of a plurality of cross-points either in the same row or in the same column without causing the erroneous operation of nonselected cross-points. The switch matrix is of the divisionally excited type having a magnetic shunt plate with sealed switches disposed in through apertures therein at cross-point locations. First, second, third and fourth windings are wound around the sealed switches so as to generate control magnetic fields for controlling the operations of the respective sealed switches. An asymmetrical magnetization is given to the sealed switches with respect to the top and bottom planes so that there is a difference in the magnetization of the sealed switches on either side of the shunt plate when driven by the windings.

摘要： A divisional excitation type coordinate switching device featuring a single magnetic shunt plate and preformed elongate excitation coils arranged on the top and bottom sides thereof and each surrounding a row or column of switching elements. Terminal blocks are secured to the four sides of the shunt plate, enabling arrangement of component parts in a fully developed formation. Outstanding among the advantages gained are substantial reduction in winding cost and overall size, ease of assembling and improved operational reliability.
