Chip touch switch

The invention relates to a chip touch switch, which comprises a metal elastic chip and welding points at four corners of the metal elastic chip. The metal elastic chip with the horizontal periphery and the arched middle is directly and integrally formed by stamping; the welding points are welded to a circuit board to form a first electrode according to an electronic welding process; the metal elastic chip is pressed by an external force to enable contact of the arched portion with a contact point on the circuit board to form a second electrode, the first electrode and the second electrode areconnected to form a closed circuit, and a switch function is triggered. By the design, assembly of multiple parts for the touch switch is avoided, so that materials and production time are saved, andefficiency and stability are improved. 本发明涉及种片式轻触开关，包括金属弹片，其直接通过冲压体成型，所述金属弹片四周水平中间拱起；以及焊接点，其设置在所述金属弹片的四个角处，所述焊接点通过电子焊接工艺手段焊接到电路板上，形成第电极；所述金属弹片通过外力按压将拱起部分与电路板上的接触点接触，形成第二电极，第电极和第二电极接通形成闭合电路，开关功能导通。采用以上设计，能够使轻触开关不需要多个部件组装，节约材料和生
