SWITCH FOR SWITCHING OF ELECTRIC CIRCUITS Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: switch for switching of electric circuits has body incorporating four ring magnets put on control handle at angle of 90 deg with reference to each other equidistantly from axis of control handle for longitudinal-angular movement with respect to hermetically sealed reed relays mounted in pairs with angle of 75 deg to printed circuit board at distance of 7.5 mm from each other and with angle of 150 deg between hermetically sealed reed relays. In this case axes of hermetically sealed reed relays and magnets are not parallel. Buttons are positioned on cover of switch body to generate one- time commands. For control over switch there is control handle composed of two parts intercoupled by self-tapping screws. Conical spring placed between body cover and lever forms joint with base. Positioning of hermetically sealed reed relays at angle of 75 deg to printed circuit board provides for one-time operation of them thanks to abrupt change of magnetic field in central section of hermetically sealed reed relay which makes it possible to make run of control button withins 3-4 mm. EFFECT: enhanced switching efficiency. 2 cl, 4 dwg
