LOCKOUT SWITCH OF AUTOMATIC REVERSER OF MOTOR USING SUDDEN VIBRATION GENERATED IN BODY OF PORTABLE MOTOR-DRIVEN HAND DRILL AND MOTOR-DRIVEN HAND DRIVER

摘要

PROBLEM TO BE SOLVED: To provide a device for turning on a lockout switch of an automatic reverser of a motor, by using sudden vibration generated in a body of a portable motor-driven hand drill and a motor-driven hand driver.;SOLUTION: (1) An electrically conductive column 3 is installed in one circuit 2 of the lockout switch 1. (2) An electrically conductive plate 4 is installed on the electrically conductive column 3. (3) An electrically conductive weight 5 is installed on the electrically conductive plate 4. (4) An electrically conductive enclosure 9 is arranged around the electrically conductive weight 5 so as not to touch the electrically conductive weight 5. (5) Another one circuit 6 of the lockout switch 1 is installed in a part of the electrically conductive enclosure 9.;COPYRIGHT: (C)2005,JPO&NCIPI
