Therefore, only by the operator's vision to identify the accuracy of the operation, because there is no appropriate feedback information that indicates whether the finger is pressed in the effective range of the switch to make the switch action, thus affecting the confidence of the monitoring of the whole machine and the speed of operation.


    However, the membrane switch button drum is more enhanced visual, not only can accurately given the range of key body, improve the recognition speed, so that the operator's sense of touch is more sensitive, but also enhance the decorative effect of the product appearance.
