Title:
FLUCTUATION DISK SELECTOR
Document Type and Number:
Japanese Patent JP3197890
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device for a high-integrated radio frequency transceiver allowing selection or change of a component deciding a different operation frequency.
SOLUTION: A switch 11 is formed by use of a micro electromechanical system (i.e., a fluctuation motor). The switch 11 comprises a non-conductive flat substrate 13 having a center support post 15 and a center electrode D0, and a conductive circular rotor 17. The substrate 13 has drive rings 21 including drive electrodes D1-D12, and switch rings 23 including switch contact pieces S1-S12. The respective drive electrodes D1-D12 can pull down the rotor 17 to bring the rotor 17 into contact with the switch contact pieces S1-S12 corresponding to the drive electrodes D1-D12. For example, when the drive electrode D3 is operated, the rotor 17 is inclined right to come in contact with the switch contact piece S3 at the three o'clock position. As a result, the center electrode D0 is electrically connected to the switch contact piece S3.
