Title:
SWITCH DEVICE PROVIDED WITH WATER-PROOFING STRUCTURE
Document Type and Number:
Japanese Patent JP3025942
Kind Code:
B2
Abstract:
PURPOSE: To solve a conventional problem that adhesion strength of a water- proofing cover to prevent water infiltration between a terminal base and a case decreases due to the expansion or the shrinkage by heat.
CONSTITUTION: A water-proofing cover 51 which covers the outer surface of a switch device 50 is made of synthetic resin having the same or similar coefficient of linear expansion as or to that of a terminal base 3 by double-molding with the terminal base 3. A circular uneven part 52a is formed in an opposite face of the case 52 which is set face to face and joined with the water-proofing cover 51 and the synthetic resin of the water-proofing cover 51 is closely joined with the circular uneven part 52a.
