Abstract
The switch comprises, incorporated in its casing (2), an upper circuit board (16) which carries a control electronic circuit (18) and a lower circuit board (24) which carries power components, such as relays (26), for the feed power supply of the apparatus to be controlled. Both superposed boards (16, 24) are linked together, mechanically and electrically, by linking pillars (40). Application to the automatic control of a window lifting device or to the delay control of window heating device on cars.
Claims11
In a switch for the control of an electrical device the improvement comprising, in combination, a first circuit board and a second circuit board stacked together in spaced, overlying relation, said first board carrying a control electronic circuit for relatively low electrical current, the second board carrying a power circuit comprising at least one means for switching a relatively high electrical current, said second board also carrying connecting means for joining to the apparatus to be controlled, and electrically conductive linking pillar means joining the first and second boards together in firmly fixed relation to each other, said linking pillar means also providing electrical connection between the respective circuits of said first circuit board and second circuit board, whereby the switching means may be controlled by the control electronic circuit.
A switch for the control of an electrical device, said switch comprising a first circuit board and a second circuit board rigidly positioned together in side-by-side, facing, spaced, electrically interconnected relation, said first board carrying a control electronic circuit for relatively low current, said second board carrying a power circuit comprising at least one switching device for relatively high current, said second circuit board also defining means for electrical interconnection with the apparatus to be controlled, the face of said first circuit board which is opposed to the second circuit board carrying at least a pair of conductive metal track means as part of said control circuit, and contact means to close the circuit between respective conductive track means, said contact means being movable between circuit closing relation and spaced relation by the action of manually operated key means.
