Title:
動力式構内搬送用車両の走行駆動装置を制御するための走行スイッチ
Document Type and Number:
Japanese Patent JP4733188
Kind Code:
B2
Abstract:
The switch has two hall-effect sensors (1, 2) arranged at a lateral distance from one another. A source of magnetic flux lines are displaced relative to the hall-effect sensors when the switch is actuated, such that the magnetic flux density in the hall-effect sensors is changed. The hall-effect sensors are arranged evenly on a side of a printed circuit board. The source of flux density lines comprise two permanent magnets (3, 6) that are arranged at a distance from each other. A yoke (7) for conducting the magnetic flux lines is provided on a side of the board.
