Abstract

The invention provides a metal elastic sheet which is arranged on a circuit board, wherein a first contact and a second contact are arranged on the circuit board, the metal elastic sheet comprises a basal part, and the basal part is fixed on the circuit board; the basal part is connected with one end of a first movable part, a first contact part is arranged at the other end of the first movable part, the first contact part is suspended above the first contact, and elastic contact or separation is kept between the first contact part and the first contact; and the basal part is also connected with one end of a second movable part, a second contact part is arranged at the other end of the second movable part, the second contact part is suspended above the second contact, and elastic contact or separation is kept between the second contact part and the second contact. The metal elastic sheet has simple structure and realizes the diversified operation of the metal elastic sheet by touching the first contact through the first contact part and touching the second contact through the second contact part.

Description

【Technical field】 [0001] The invention relates to a metal shrapnel, in particular to a metal shrapnel with simple structure and multiple operations. 【Background technique】 [0002] Metal dome belongs to the button switch, which is generally divided into normally open switch and normally closed switch. In some fields, two metal domes need to be opened or closed at the same time during work. [0003] Mainland China Patent Application No. 95222408.9 discloses a compound multi-contact control switch, which includes a sliding bottom plate and a connecting plate with push pieces installed between the bottom shell and the cover with the wire seat, and the connecting piece and the connecting plate are fixed on the sliding bottom plate. The transition piece is also installed on the cover with a push-button or swivel sliding housing. The utility model has the advantage that when a plurality of the utility models are used to control multiple electrical appliances, pressing any one of ...
