ABSTRACT:
A scroll wheel device with a thin film type command switch mainly replaces conventional optical grating switch during rotation of a wheel for outputting a signal. The thin film type command switch is a flexible circuit board, and is provided with a circuit arrangement corresponding to a rotating trajectory of the wheel. The wheel is provided with a pressing portion which is simultaneously driven during rotation of the wheel and pressing the thin film type command switch for outputting different command signals. The thin film type command switch of the present invention can decrease the manufacturing cost and save the installation space of the scroll wheel device.
