INERTIAL FORCE SWITCH

摘要

PROBLEM TO BE SOLVED: To provide a high-reliability inertial force switch capable of preventing wear of a contact electrode part and wear of an inertial body. SOLUTION: This inertial force switch is composed of: a conductive plate spring 4 having one end fixed to a fixed spacer 5 in a cantilever form; the inertial body 3 disposed on a flexible member movable substantially vertically to the plate spring 4 by receiving inertial force; an inertial body guide member 1 provided with a guide part 1a for positioning the inertial body 3 and for guiding the inertial body 3 in the movable direction; and a plate spring 6 fixed with one end interposed between fixed spacers 5a and 5b. The other end of the plate spring 6 without being fixed is so disposed and fixed as to be positioned oppositely to the other non-fixed end of the plate spring 4. COPYRIGHT: (C)2005,JPO&NCIPI
