Key switch with lamp and assembly method thereof

Abstract

The invention discloses a key switch with a lamp and an assembly method of the key switch with the lamp. The key switch with the lamp comprises a base seat, a static contact, a moving contact, an upper lid and a key, wherein a hanging table is arranged on the key, and a through groove, a first giving-way groove, a second giving-way groove and a moving groove are formed in the upper lid. When the key switch with the lamp is assembled, firstly, the hanging table is aligned with the second giving-way groove and the key is pressed downwards so that the key enters the first giving-way groove and the through groove; then the key is moved laterally to enable the hanging table to enter the moving groove, and therefore the key is enabled to totally enter the through groove; and finally, when the upper lid and the base seat are assembled, a first filling block and a second filling block are respectively embedded in the first giving-way groove and the second giving-way groove, and therefore fast assembly of the key switch with the lamp is achieved. The key switch with the lamp and the assembly method of the key switch with the lamp are simple in structure, ingenious and easy to assemble, few in technological process of production, beneficial to the improvement of production efficiency and reduction of manufacturing cost, easy in bulk order production, capable of meeting market demands and small in part quantity so that the stability of electrical performance and mechanical performance can be guaranteed, and the quality of the key switch with the lamp is greatly improved.

Description

technical field [0001] The invention relates to the technology in the field of key switches, in particular to a key switch with light and an assembly method thereof. Background technique [0002] At present, key switches are widely used in various fields such as instruments, meters, medical equipment, power systems, industrial automation control, etc. During the operation of traditional key switches, users cannot intuitively judge the on / off status of the key switch, so use It will multiply the trouble when the operator operates. At present, there are some illuminated key switches on the market, which generally embed the indicator light on the side edge of the switch housing, so that the light emitted by the indicator light is unevenly distributed on the keycap, and the whole body of the keycap cannot be illuminated; especially Yes, the existing key switches with lights are complex in structure, complicated in production process, difficult to assemble due to many scattered ...
