Abstract
Abstract Electrical system for an automobile vehicle, comprising a plurality of apparatuses, such as direction-changing indicators, to be supplied with power. A main switch having an ''''on'''' contact is interposed between the apparatuses and the power source. A second switch is connected in series between the source and those of the apparatuses which are desired to operate in a cadenced manner. A cadenced signal generator is interposed between the ''''on'''' contact of the main switch and ground and is adapted to actuate the second switch in a cadenced manner.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
An electrical system for an automobile vehicle, comprising a source of d-c current, a first group of apparatuses which must be supplied with power from said source in a cadenced operation mode and a second group of apparatuses which must be supplied with power from said source either in a cadenced or in a continuous operation mode, a main switch comprising an ''''on'''' contact, circuits connecting said apparatuses to said source through said main switch, a second switch, and a line connecting the second switch in series between the source and said apparatuses, a cadenced signal generator connected between the ''''on'''' contact of the main switch and ground for actuating said second switch and a direct supply line connected between said main switch and third switches respectively inserted in series between said second switch and each of apparatuses of said second group for switching the same from said cadenced operation mode to said continuous operation mode.
Claim 2
Dependent Claim
156 words
An electrical system for an automobile vehicle, comprising a source of d-c current, a first group of apparatuses which must be supplied with power from said source in a cadenced operation mode and a second group of apparatuses which must be supplied with power from said source either in a cadenced or in a continuous operation mode, a main switch comprising an ''''on'''' contact, circuits connecting said apparatuses to said source through said main switch, a second switch, and a line connecting the second switch in series between the source and said apparatuses, a cadenced signal generator connected between the ''''on'''' contact of the main switch and ground for actuating said second switch and a direct supply line connected between said main switch and third switches respectively inserted in series between said second switch and each of apparatuses of said second group for switching the same from said cadenced operation mode to said continuous operation mode.
Claim 3
Dependent Claim
47 words
A system as claimed in claim 1, wherein said apparatuses of said first group comprise direction-changing indicators and signalling and warning indicators mounted on the instrument panel of the vehicle and said apparatuses of said second group comprise a windscreen washer motor and a windscreen wiper motor.
Claim 4
Dependent Claim
46 words
A system as claimed in claim 2, wherein said second switch is a switch having two positions and first and second contacts, said first contact being connected to said windscreen washer motor and to said windscreen wiper motor through respective third switches and to said direction-changing
Claim 5
Dependent Claim
60 words
A system as claimed in claim 1, wherein at least one of said apparatuses of said second group must be supplied in a cadenced operation mode at a rate lower than the frequency of said second switch, said system comprising a frequency divider interposed between the second switch and said at least one of the apparatuses of said second group.
Claim 6
Dependent Claim
64 words
A system as claimed in claim 1, comprising vehicle direction-changing indicators, a fourth switch for simultaneously actuating the indicators, a fifth switch connected to be actuated at the same time as said fourth switch, a supply line for supplying power to the signal generator and to the second switch in parallel with the main switch, said supply line being controlled by said fifth switch.
