A contact is made between the spring and the contact unit. Longitudinal recesses (22, 24) are provided in a contact end of the contact unit. A contact head extending in the direction of the contact unit is provided at the end of the spring and is gripped to make a contact between the contact unit and the spring in the recesses. The head is formed such that the head contacts longitudinal sides of the recesses.
