Abstract

A switchgear that can cope with both high-load areas and micro-areas, is less prone to arc consumption at high loads, and can obtain stable contact. Formed on the movable contact (7) is a first contact portion (7b) in sliding contact with the common fixed contact (2), and a second and third contact portion (7c, 7d) in sliding contact with the individual fixed contact (3), On the single fixed contact (3) along the direction perpendicular to the lifting direction of the drive member (9), form the first contact portion (3c) for arc consumption that first contacts the second contact portion (7c), and then contacts with the second contact portion (7c). The 2nd contact part (3d) that the 3rd contact part (7d) contacts, the bottom side of the 2nd contact part (3d) is used as the sliding contact surface with the 3rd contact part (7d), at the same time the first contact part (3c ) is formed on the track of sliding contact with the second contact part (7c) on the lower surface side of the second contact part (7c).

Description

technical field [0001] The present invention relates to a vehicle-mounted switch device, and more particularly to a structure using a switch device for lighting when a door of an automobile is opened and closed. Background technique [0002] As the structure of the conventional switchgear, since it is necessary to switch the lamp load, a microswitch-type detection switch that can be used in a high-load area is used (for example, refer to Patent Document 1). [0003] Hereinafter, the configuration of a conventional microswitch type switch device for vehicles will be described with reference to the drawings. Figure 9 It is a sectional view showing the structure of a conventional microswitch type switchgear. [0004] exist Figure 9 Among them, the switch device consists of a base 52 and a cover 53 to form a housing 51 . Contacts 56 , 57 , 58 are inserted into the base 52 , and one end thereof protrudes outward to form connection contacts 60 , 61 , 62 . In addition, the cont...
