PROBLEM TO BE SOLVED: To improve a contact property of a movable contact 12 to a stationary contact point 13f of a stationary contact 13 in simple configuration.SOLUTION: A contact point recess 13a2 is formed in such a manner that a tip edge of a folded extension part 13a1 of the stationary contact 13 to/from which the movable contact 12 is abutted/separated is notched. The stationary contact point 13f is provided in a plate thickness end face in an inner peripheral edge forming a notched space of the contact point recess 13a2. An edge portion of a tabular member forming the movable contact 12 is brought into contact with and separated from the plate thickness end face including the stationary contact point 13f. Therefore, the edge portion of the movable contact 12 is brought into press-contact onto the plate thickness end face including the stationary contact point 13f of the stationary contact 13, then moved in a rubbed state and stopped thereafter, thereby providing an electrical contact state. An electrical connection property can be maintained excellent by so-called wiping effects that are obtained in the electrical contact state.SELECTED DRAWING: Figure 24 |
