Motor driven blower input control circuit


PURPOSE:To clean by intermittent operation by simply turning ON and OFF by natural operation whether the handy base of a hose is grasped or not by providing the first switch and the second switch of grasping operation type in parallel connection. CONSTITUTION:When cleaning intermittently while arranging furnitures, the handy base of a hose is intentionally grasped to clean while allowing the first switch 18 to remain OFF. At this time, the second switch 19 is closed to set a variable resistor circuit to connected state, thereby cleaning. When furnitures are arranged, a hand is released from the handy base of the hose to then turn the switch 19 OFF. Thus, the variable resistor circuit is opened to stop a motor driven blower 8.
