Abstract
Rotary-controlled multipole electric switch fitted with a handle (4) and a housing (1) in which a cam device transforms the rotation of the handle into a translational movement of contact bridges (21). In order to ensure coordination between a cylindrical control core (13) and a slider 16 bearing contact bridges, the cam device is fitted with at least two notches (19, 20) offset around the axis of rotation X of the knob (4c), and with a control projection (14) applied respectively to the bottom of one notch in the OFF position and to the bottom of the other notch in the ON position by the force supplied by springs (24) acting on the slider and contact pressure springs (22).
Claims9
Rotary-controlled multipole electric switch having an ON position and an OFF position, comprising a housing fitted with a control handle rotatable about a rotational axis, said housing including several movable contact bridges disposed in a slider, said slider being capable of translational movement, a core having a cam, said core rotating with the rotating handle and the cam coordinates with the slider to translate the slider,
- a cam follower on the slider comprising at least two notches offset in relation to one another around the axis of rotation of the handle, the cam comprising at least one control projection that in the ON position is pressed against one of the notches and in the OFF position is pressed against another of said notches by the force exerted by springs on the slider.
