Claim 12:
13. An electrical connection device for signaling vehicles, enabled to be linked materially and electrically to an external support of the vehicle to be signalized that has an electric potential difference, and at the same time enabled to be linked materially and electrically to an external electrically lighting operated device for signaling the vehicles, and therefore transmitting electric potential between said external support and said lighting device, the electrical connection device comprising:
a base that incorporates a spring and a shaft enabled for receiving and transmitting the electric potential difference from the external support, and being arranged on the same base, wherein in order to make electrical contact with the support, the shaft is electrically connectable to both an internal terminal of the support and to a terminal for wires, wherein the spring further comprises opposite terminations for electrically contacting, respectively, another terminal for wires and the support, the spring being movable inside the base, by means of a compressive force on said spring for switching between transmitting the electrical potential, when the shaft is in contact with the external support, and not transmitting the electrical potential, when the shaft is not in contact with the external support;
the electrical connection device further comprising a coaxial second hollow cylindrical housing extending from the base in a direction opposite to the first cylindrical housing, and internally in communication and in continuity with the inside of the first cylindrical housing, wherein the second cylindrical housing is enabled to contain the spring arranged in the very contour there and around the same axial axis, thereof, the terminations of the spring comprising a straight termination parallel to the axial axis thereof and protruding from the same second cylindrical housing at the end of the same second cylindrical housing opposite its contact with the base itself.
