Abstract

The invention discloses a switch using a torsional spring as a terminal. The switch comprises an upper cover, a base, a fixed terminal, a movable terminal and a pressing piece, wherein the base is provided with a guide post; the pressing piece is connected to the guide post sleeved with a return spring; the upper end of the pressing piece protrudes out of the upper cover for pressing; the upper cover is buckled with the base, so that a cavity is formed between the upper cover and the base; the fixed terminal and the movable terminal are arranged in the cavity; one end of the fixed terminal and one end of the movable terminal penetrate through base and are connected with an external circuit; the movable terminal is the torsional spring and is mounted on the end, adjacent to the fixed terminal, of the base; one end of the torsional spring penetrates out of the base for line connection and is fixed to the base; and the other end of the torsional spring serves as an action arm controlled by the pressing piece to contact with the fixed terminal. Compared with the prior art, the torsional spring having good elasticity is adopted as the movable terminal, so that the switch using the torsional spring as the terminal can provide better operation experience. Besides, the torsional spring is comparatively low in manufacturing cost. The switch is simple in structure and long in service lifetime. .

Description

technical field [0001] The invention relates to an electronic switch, in particular to a switch using a torsion spring as a terminal. Background technique [0002] Many operations of existing devices require the use of key switches as input means. The quality of the key switch determines the experience of the input device, and it is necessary to ensure a good feel and service life. The existing key switch adopts the movable contact piece made of metal sheet. Due to the limitation of the internal space of the switch, the strength of the metal sheet is relatively insufficient, which affects the feel and life of the key. Contents of the invention [0003] In view of this, the problem to be solved by the present invention is to provide a switch using a torsion spring as a terminal with good hand feeling, long service life, simple structure and low manufacturing cost. [0004] In order to solve the above problems, the present invention adopts the following technical solutions:...
