ABSTRACT:
A knitting counter for counting stitches or rows of stitches comprising: a counter casing having a flat bottom surface to be placed in substantially horizontal flat support surface and formed with a reception opening as well as with a window opening; an operating member having a touch portion projecting out through the reception opening as movably guided thereby and a pusher portion extending within the casing; a digital display device disposed at the window opening; and an electrical control circuit arranged within the casing and connected to the display device for controlling thereof; wherein the control circuit incorporates a self-openable count input switch which, when closed each time, functions to change a numerical indication of the display device one by one, the pusher portion is in permanent engagement with the count input switch, and the counter casing has such a shape as to be prevented from toppling down upon a normal push on the touch portion.
