<P>PROBLEM TO BE SOLVED: To provide a micro-mechanical switching device with low loss, high isolation, low drive voltage, and short switching time. <P>SOLUTION: A switching device 1a comprises: a drive part including a fixed electrode 2 and a movable electrode 3; a push rod 4 mechanically connected to the movable electrode 3; a movable contact element mechanically connected to one side of the push rod 4; at least one restoring spring 5 mechanically connected to the push rod 4; and signal lines 7a and 7b and ground line 13. In a shunt setup, a contact beam 6 is provided to close and release an ohmic contact between the ground line 13 and the signal lines 7a and 7b. The ground line 13 is provided with at least one contact bar 12 extending through a gap between the signal lines 7a and 7b so that the ohmic contact is formed between the contact beam 6 and the ground line 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
