Manufacturers of keyboard switches in China are diversifying their product offerings, adding magnetic variants to their predominantly mechanical catalogs. For both types, they plan to introduce models with a longer life span measured in cycles that are considered synonymous with keystrokes in China.
Huizhou Jiadalong Electronic Technology Co. Ltd, a supplier interviewed by Global Sources, has presented its KS-20U series of dual-rail magnetic keyboard switches. In addition to a 150 million-keystroke life span, these components have a rapid trigger mode, offer freely-setting travel and ensure immediate actuation with no feedback.
In the mechanical subcategory, there are linear and tactile types with three or five pins and a minimum life span of 50 million cycles. Both have water-resistant versions with an above IP65 rating. These devices, with 3 to 20N insertion and withdrawal force, have a rated voltage ranging from 2 to 30VDC, maximum contact resistance of 200mohms and minimum insulation resistance of 100Mohms. The typical operating temperature is -30 to 85 C.
Most manufacturers ensure their keyboard switches comply with industry safety standards such as UL, CE, GS and RoHS. They usually source materials, such as stainless steel, copper, PC and nylon used in making springs, stems and housings, from domestic suppliers. The cost of these manufacturing inputs is expected to remain the same in the coming months and will keep product prices steady.
