Abstract

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.

Description

technical field [0001] The invention relates to keys of electronic products, in particular to a chip type light touch switch. Background technique [0002] The tact switch is an electronic switch and belongs to the category of electronic components. Also known as key switch, it first appeared in Japan [called: sensitive switch] when used to meet the operating force conditions to apply pressure to the switch operation direction. The switch function is closed and turned on. When the pressure is removed, the switch is disconnected. Its internal structure The on-off is realized by the force change of the metal shrapnel. Light touch switches have the advantages of small contact resistance, precise operating force error, and diversified specifications. They are widely used in electronic equipment and white goods, such as: audio-visual products, digital products, remote controls, communication products, household appliances, etc. Electrical appliances, security products, toys, co...
