Abstract

The invention relates to a key gap control structure, a wall switch and a multi-key product. The key gap control structure comprises a key housing, a plurality of keys, and a positioning layer. The plurality of keys are detachably connected with the key housing, and a cross-shaped rib is arranged on the back surface of each key and is used for triggering a switch elastic sheet; the positioning layer is fixedly arranged between the key and the key housing, a plurality of cross-shaped hole grooves matched with the cross-shaped ribs are formed in the positioning layer, the cross-shaped ribs can penetrate through the cross-shaped hole grooves, and the positioning layer is an integrally-formed metal sheet. By arranging the positioning layer, the positioning ribs and other positioning interfaces, the problem that the key gaps of the multi-key switch controller are not uniform is effectively solved, and the gaps between keys and the use hand feeling of the keys are optimized.

Description

technical field

[0001] The application relates to the field of home appliances, in particular to a key gap control structure, a wall switch and multi-key products. Background technique

[0002] At present, the existing technology is aimed at the multi-button remote control or wall switch products on the market. There are often uneven gaps between the buttons and the buttons, and between the buttons and the button shell. The real reason is that the buttons are generally made of plastic or plastic plus silicone. The button shell is also set to be made of plastic material. The plastic material has a large linear expansion coefficient and poor dimensional accuracy. The plastic or silicone key is directly matched with the plastic key shell, and the gap between the key and the key shell and between the key and the key is poor. . At present, no effective solution has been proposed for the problems of poor dimensional accuracy and gap control of keys in related technologies. Cont...
