Title:
BREAKER DEVICE
Document Type and Number:
Japanese Patent JP3753943
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a breaker device that can be down sized and generation of contact failure between a moving electrode and a fixed electrode can be prevented.
SOLUTION: In the breaker device, a pair of fixed electrodes 35 and 35 are installed to sandwich a projecting wall 32 and a circuit is closed by fitting a U-shaped moving electrode 60 to both of them. A protecting projection 61 is provided on a top edge of the fixed electrode 35 and projecting points 62 are provided on both sides of it. When the mobile electrode 60 is fitted, it is opened and deformed elastically by coming into contact with the projecting points 62. Even when the projecting points 62 is scraped off due to friction between the projecting points 62 and the moving electrode 60, since the projecting points 62 are in a position that is always from the fixed electrode 35, the scraped powder does not stick in between the fixed electrodes 35.
