摘要:
The invention relates to a carrier (1) for electrical and/or electronic components, in particular a circuit board, having a broadside (2) for receiving electrical conducting paths (4) and having a narrow side (3). According to the invention, at least one electrically conductive contact surface (5) is provided on the carrier (1), wherein the contact surface (5) in particular serves as a fixed contact for an electrical switch. The contact surface (5) is arranged on the narrow side (3).

The invention relates to a plastic component having at least one electric contact element, which has a plastic body and at least one electric conductor track, by means of which the electric contact element can be electrically connected. According to the invention, the plastic component is produced by means of a combined injection molding and metal casting process, in which the plastic body is produced by means of an injection molding process and the at least one electric conductor track is produced by means of a metal casting or metal spraying process, wherein the component formed last is injection molded onto the component formed previously. The invention further relates to a method for producing a corresponding plastic component.

The object of this invention is to provide a silver-coated material of excellent abrasion resistance in which, even when used as, for example, a moving contact and/or a fixed contact in a switch used over an extended period of time under conditions where switching is repeatedly carried out, the silver or silver alloy layer at the surface does not wear away and, moreover, the contact resistance does not rise. A silver-coated material having, as an outermost layer on an electrically conductive base material, a layer made of at least silver or a silver alloy, this silver-coated material having a coating loss, in an abrasion resistance test, of less than 40 mg and having an initial contact resistance of less than 10 mΩ and a contact resistance of less than 10 mΩ after a sliding wear test carried out under certain conditions.

A switching electrical power contactor (10) having a bi-blade type switch, has ferrous plates (40) attached to the blades to increase the current carrying capacity and reduce the resistance of the switch. The contacts (60, 62) of the switches are arranged in pairs with at least one pair of contacts (60) being arranged to close before another pair of contacts (62).

A switching electrical power contactor (10) having a bi-blade type switch, has ferrous plates attached to the blades to increase the current carrying capacity and reduce the resistance of the switch. Flexible tangs (44) formed at the distal end of the blades cooperate with a movable member (52) to hold the contacts closed when the contactor (10) is in the closed state.
