Abstract
Abstract An electrical multipolar switch having several rotary angular positions for providing the required connections in an electrical equipment by means of stationary plugs and movable strips, wherein the improvement consists in the provision of independent contact strips set into a base made from insulating and resilient material without any connections between each other inside of said base, said strips being formed each one endwise with a top bent at right angles and frictionally engageable with stationary plugs distributed angularly in several azimuthal directions about the switch axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
An electrical multipolar switch having several rotary angular positions for providing the required connections in an electrical equipment, including a stator provided with stationary plugs angularly distributed about a switch axis and a base axially movable in said stator, made from insulating material and strips set into said base without any connection between each other inside of said base, said strips being engageable with said stationary plugs, wherein the improvement comprises a rotor provided with means engaging with means provided in the stator for imparting to said rotor a helical movement upon rotation thereof and in that said base is axially aligned with and carried by said rotor and mounted non-rotatably in said stator, whereby the rotary motion of said rotor is converted in a translatory motion of said base and said contact strips.
Claim 2
Dependent Claim
134 words
An electrical multipolar switch having several rotary angular positions for providing the required connections in an electrical equipment, including a stator provided with stationary plugs angularly distributed about a switch axis and a base axially movable in said stator, made from insulating material and strips set into said base without any connection between each other inside of said base, said strips being engageable with said stationary plugs, wherein the improvement comprises a rotor provided with means engaging with means provided in the stator for imparting to said rotor a helical movement upon rotation thereof and in that said base is axially aligned with and carried by said rotor and mounted non-rotatably in said stator, whereby the rotary motion of said rotor is converted in a translatory motion of said base and said contact strips.
Claim 3
Dependent Claim
108 words
A switch according to claim 1 wherein said stator is provided with an axial bore formed with an helical groove and with a longitudinal groove extending in parallel relation to the axis of rotation of the switch, said rotor rotatably mounted in said bore of said stator and provided with a radially outward projecting feather engaging said helical groove, said rotor carrying a non-rotatable cup-like member formed with a radially outward projecting spigot slidably engaging said longitudinal groove of said stator, whereby the rotary motion of said rotor is converted into a translatory motion of said cup-like member and said base is held firmly within said cup-like member.
Claim 4
Dependent Claim
51 words
A switch according to claim 2, wherein said rotor carries a resilient base member into which said movable strips are set and said movable strips are provided with T-shaped bent tips each having two outwardly projecting contact areas arranged to provide an electrical contact between said stationary plugs when contacting same.
Claim 5
Dependent Claim
60 words
A switch according to claim 3, comprising cleaning means for the contacting areas where electrical current is flowing therethrough, whereby the combined driving of said rotor according to a rotory and a translatory motion results in a linear displacement of said contact strips and successive frictional rubbing engagment thereof with said stationary plugs to achieve the cleaning of said areas.
Claim 6
Dependent Claim
14 words
Switch according to claim 4, wherein said movable strips are made from non-resilient material.
