Title:
TIPPING SWITCH
Document Type and Number:
Japanese Patent JP2018181449
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve such problems of conventional ON type tipping switch using a resin case that there is a problem in the long term performance because it cannot be airtight structure, and that the structure is complicated for obtaining electrical insulation in the switch, when a metal closed container is used.SOLUTION: In an ON type tipping switch 1 for opening and closing a contact mechanism by means of a spherical inertia 11 placed in a metal closed container, a movable contact support 10 is placed above the inertia 11, and both are made to have the same potential. When tilting more tha a prescribed angle, the inertia 11 pushes up the tip 10B of the movable contact support and disconnects a movable contact 9 and a fixed contact 8. A metal limit member 12 is fixed to become the same potential as the movable contact 9 in the container, and the limit member 12 limits movement of the inertia 11 within a prescribed range thus preventing contact with a different potential part. Consequently, there is no energization at the time of overturn, and the inertia never causes plastic deformation of components of a contact mechanism with impact.SELECTED DRAWING: Figure 1
