Thin switch and display panel provided with switch |
摘要 |
When pressing a pushbutton (12) in this thin switch (40), the pushbutton (12) rotates at a constant stroke until a lower end of this pushbutton (12) on the side of a permanent magnet (16) comes into contact with a lower display panel (22). Following this rotation, positional relation between the permanent magnet (16) and a Hall element integrated circuit (44) corresponding to this pushbutton (12) changes and the Hall element integrated circuit (44) detects change of a magnetic field by the permanent magnet (16), whereby the pressing operation of the pushbutton (12) is detected. When the pushing operation is canceled, the pushbutton (12) is returned to the original state due to attractive force of the permanent magnet (16) and a magnetic body (18).
