Patent number: 8556667Abstract: A space-saving terminal includes a depth that is short and a floor space that is small. The terminal further includes a fixing part for press-in pressed into and fixed to a base material, a support part projected upward so as to cross with the fixing part for press-in, two extension parts extended downward while meandering from a branch portion on a tip of the support part so as to form a meandering slit, and a movable contact part projected from a tip portion formed by integrating free ends of the extension parts so as to be capable of moving in and out of a contacting hole of the base material. The support part is curved outward in order to avoid contact with the tip portion of the extension part while the tip portion is displaced.Type: GrantFiled: March 24, 2011Date of Patent: October 15, 2013Assignee: OMRON CorporationInventors: Jiro Koyama, Hirotada Teranishi
