Abstract (en)
[origin: EP0325138A1] A method for attaching a contact part (1), for stepping switches, which is fixed with a shank in a hole of a cylindrical wall (4) consisting of wound dielectric material. The contact part has a connecting surface on the outer side and an electrode shape (3) on the inner side. Onto the shank of the contact part (1) there is initially pushed a dielectric material sleeve (2) which abuts against the electrode shape (3), the contact part (1), together with the dielectric material sleeve, is then pushed from outside into the hole of the cylindrical wall (4) and the dielectric material sleeve (2) projecting on both sides of the cylindrical wall (4) is locked. Thereafter, the contact part (1) with the electrode shape (3) is pushed into the dielectric material sleeve (2) until the latter expands and rests firmly on the inner side of the dielectric material wall (4). The contact part (1), together with the dielectric material sleeve (2), is then fixed on the outer side of the wall. <IMAGE>
