Abstract
Abstract This arrangement relates to a locking device such as a cylindrical switch for ignition and starting of an engine and other like uses. The switch has an insulated, hollow cylindrical stator with a plurality of contact blades mounted on the inner surface parallel with the cylinder axis and connected to ignition and starting means and other accessories. A rotor is positioned in the hollow stator and comprises an insulated cylinder carrying a conductive plate having a shape formed in steps to ensure contact with the blades. An insulated driving element, controlled by the locking device, is assembled by resilient fitting means to the rotor. A cam on the driving element engages with the blades to selectively break the connections.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
A control switch for ignition and starting of a motor vehicle engine, and other uses more particularly for energizing different means and accessories of an automotive vehicle in combination with antitheft locking devices, said switch comprising a fixed insulated stator having a hollow cylindrical form, a plurality of contacts formed by resilient blades mounted within one end of said hollow stator and extending along the inner surface thereof parallel to the longitudinal axis of the stator, an insulated cylindrical rotor rotatably mounted in said stator, a conductive plate formed on the outer peripheral surface of the rotor and having a stepped configuration for selectively making contact with said contact blades, the length of each step being determined by the desired duration of the contact between said plate and said contact blade, means to rotatably drive said rotor having a cam portion for breaking contact between said contact blades and said plate, and means on said rotor driving means holding it in an assembled condition in said rotor.
Claim 2
Dependent Claim
167 words
A control switch for ignition and starting of a motor vehicle engine, and other uses more particularly for energizing different means and accessories of an automotive vehicle in combination with antitheft locking devices, said switch comprising a fixed insulated stator having a hollow cylindrical form, a plurality of contacts formed by resilient blades mounted within one end of said hollow stator and extending along the inner surface thereof parallel to the longitudinal axis of the stator, an insulated cylindrical rotor rotatably mounted in said stator, a conductive plate formed on the outer peripheral surface of the rotor and having a stepped configuration for selectively making contact with said contact blades, the length of each step being determined by the desired duration of the contact between said plate and said contact blade, means to rotatably drive said rotor having a cam portion for breaking contact between said contact blades and said plate, and means on said rotor driving means holding it in an assembled condition in said rotor.
Claim 3
Dependent Claim
44 words
A control switch according to claim 1 wherein each of said contact blades has means on its free end to be contacted by said cam of the rotor driving means and produce a quickbreak of the contact between said contact blades and said plate.
Claim 4
Dependent Claim
25 words
A control switch according to claim 2 further comprising an insert of hard conductive material provided on said rotor in a region of contact breaking.
Claim 5
Dependent Claim
73 words
A control switch according to claim 1, wherein said means on said rotor driving means for holding it in an assembled condition with said rotor comprises a split spindle rigid at one end with an end of said driving means and having an enlarged split head, said rotor having an axial bore through which said head passes and an enlarged recess at one end of said bore in which said enlarged head engages.
Claim 6
Dependent Claim
35 words
A control switch according to claim 4 wherein said driving means is provided with a central recess to be engaged by a driving dog solid with an operating knob of an antitheft locking device means.
