| 摘要 |
The present invention relates to an electric switching device (1), such as a relay, comprising a first and a second terminal (2, 4), a contact sub-assembly (6) having at least two contact members (8, 10) and configured to be moved from a connecting position (12), in which the contact members (8, 10) contact each other, to an interrupting position (14), in which the contact members (8, 10) are spaced apart from each other, a current path (16) extending, in the connecting position (12) of the contact sub-assembly (6) from the first terminal (2) via the contact sub-assembly (6) to the second terminal (4), said current path (16) being interrupted in the interrupting position (14) of the contact sub-assembly (6), a Lorentz force generator (1 8) comprising at least two conductor members (20, 22) located in the current path (1 6) and arranged to generate a Lorentz force (24) acting on the conductor members (20, 22) and generating a contact force (25) biasing the contact sub-assembly (6) into the connecting position (12), and at least one support Lorentz force generator (32) arranged to generate an enforcing Lorentz force (36) amplifying the contact force (25) biasing the contact sub-assembly (6) into the connecting position (12). The electric switching device (1) further comprises at least one support Lorentz force generator (32) arranged to generate an enforcing Lorentz force (36) amplifying the contact force (25) biasing the contact sub-assembly (6) into the connecting position (12). |
