ELECTRIC SWITCH Russian patent published in 1999 - IPC

FIELD: electric engineering, lever switches of light signalling of turn indicators of motor vehicles. SUBSTANCE: electric switch has handle which is coupled kinematically to rotary block carrying electric jumper, controlling cam with mechanism for return to neutral position. Key of spring-loaded pusher installed in longitudinal groove of body rests against template. Tail part of pusher is positioned inside fork of rotary block. Contact plate of audio signal rests against lever of handle mounted for angular displacements towards dielectric plate with contacts of electric circuits. Novelty of invention lies in manufacture of controlling cam in the form of truncated conical cam boss facing rotary fork facing with vertex and of contact plate in the form of flat spring. EFFECT: increased reliability of functioning of return mechanisms of translations towards contacts of turn indicators and audio signal. 7 dwg
