ELECTRONIC DEVICE
Document Type and Number:
Japanese Patent JP2017090415
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic device capable of reducing a potential difference between an electrode and a weight part, preventing the electrode and the weight part from being contacted by an electrostatic attraction and reducing the erroneous detection of acceleration detection.SOLUTION: The electronic device comprises: an acceleration switch having a weight part capable of contacting a fixed electrode when a predetermined acceleration is applied; a first terminal electrically connected with the fixed electrode; a second terminal electrically connected with the weight part; and a detection circuit connected with the first terminal and the second terminal. The detection circuit can detect acceleration without generating a potential difference between the first terminal and the second terminal.SELECTED DRAWING: Figure 1
