Contact device

A contact device for electrically contacting a removable contact finger with two electrically energized spaced-apart, parallel rail walls, said contact device comprising

• a housing having a hollow portion therein,
• at least two contact members mounted within the hollow portion of said housing, each contact member comprising a long section, a short section and an interconnecting intermediate curved section setting off the short section with respect to the long section, two contact members being mounted within said hollow portion of said housing such that they cross each other at their intermediate curved sections to form a hinge-like connection, and such that the short section of one contact member is positioned substantially in alignment with the long section of the other contact member, and also such that the short and long sections of one contact member will run substantially parallel with the short and long sections of the other contact member, the internal opposite sides of the long sections of the contact members forming the means for contacting the removable contact finger while the external sides of the short sections of the contact members, which extend outwardly of said housing, form the means for contacting the inner sides of the respective rail walls, and
• a biasing means connected between the long sections of two contact members for providing a contact pressure between the contact areas of said contact members and both the contact finger and the rail walls.
