A. Instrument Functions.
This machine is suitable for key switches, computer keyboards, conductive rubber keys, metal shrapnel keys (commonly known as pots and pans) or the same type of key strike life aging test, the use of advanced programmers to control the whole process of key life test.
At the same time for silicone rubber key for fatigue testing; with adjustable speed, the number of any setting and simultaneous testing of several products (each product can be tested at multiple points), to reach the number of times or power-down shutdown to maintain the data. Another key can be set for different pressure and different height.
At the same time the use of each striking head separate control, the design is more humanized, to meet the different testing needs of customers!
