Electrical circuit board-plug contact device

An electrical contact system, comprising:

• an electrical circuit board;
• and
• a pair of electrical contact devices adjacently arranged on the electrical circuit board and comprising a plug contact with a mating contact element, each of the electrical contact devices include:
• a first electrical contact portion mechanically fixing and electrically connecting the electrical contact device to the electrical circuit board by press-fitting;
• a second electrical contact portion forming an electrical plug contact matable with an electrical mating contact element, the second electrical contact portion has a fork structure with a pair of fork elements mechanically clamping and fixing the electrical mating contact element on the electrical contact device;
• and
• a spring portion arranged between the first and second electrical contact portions in a longitudinal direction of the electrical contact device, the spring portion electrically connects the first and second contact portions, the spring portion permits an elastic variation of a spacing between the first and second electrical contact portions in the longitudinal direction.
