Abstract
PURPOSE: To enable outputting a speed establishing signal either positive or negative rotation without any contact utilizing a diode by providing a positive or reversing use multi steps voltage dividing resistor.
CONSTITUTION: When a contact H1 is thrown in and a contact L1 is separated, a current flows from a neutral point M through a diode 13 to a terminal N from a voltage dividing resistor 1 through a diode 9 and a negative divided voltage is taken out at an output point A. At this time for example a reversing signal is obtained. And when a contact H1 is separated and L1 is thrown in, a positive rotation signal is taken out from an output point A.
