Abstract: An undetachable electrical and mechanical connection (4) between a contact element (7) has contacts (31) and a counter-contact element (8) has counter-contacts (27) with a flexible section (39) of the contact element (7) in at least the area of the contacts (31). Furthermore, the contact element (7) has at least one first and second layer (21, 22) which, in the area of the flexible section (39), define a gap (23) between them in which the counter-contact element (8) is located, the first and second layer (21, 22) each having at least one contact (31) on the inside surfaces (40) of the layers facing each other and the counter-contact part (8) having at least one counter-contact on each of its top and bottom (25, 26).

Abstract: A method for the attachment of electrical components to circuit boards where the electrical components are enclosed by a housing and held in place by a retaining device. The method enables a smaller and more compact construction for switching devices. The connection of the electrical components with the housing enclosing them creates a additional point for the absorption of thermal and mechanical stresses in addition to the connection with the circuit board.
