Title:
MAGNETIC ACTUATION TYPE MEMS SWITCH
Document Type and Number:
Japanese Patent JP2019186061
Kind Code:
A
Abstract:
To enable downsizing, fast switching and cancellation of sticking between contacts.SOLUTION: A magnetic actuation type MEMS switch 100 comprises: a first magnetic core part 120; a first signal line 15 which is provided in the first magnetic core part 120; a first contact 16 which is fixed to one end of the first magnetic core part 120 and electrically connected to the first signal line 15; a second magnetic core part 220; a second signal line 25 which is provided in the second magnetic core part 220; a second contact 26 which is fixed to one end of the second magnetic core part 220 and electrically connected to the second signal line 25; and a first coil part 111 and a second coil part 211 as magnetic field application parts including conductor coils and applying magnetic fields to the first magnetic core part 120 and the second magnetic core part 220 by making currents flow through the conductor coils. In accordance with whether the magnetic fields are applied by the magnetic field application parts, the first contact 16 is displaced and, with the displacement of the first contact 16, a connection and a disconnection of the first contact 16 and the second contact 26 are switched.SELECTED DRAWING: Figure 2
