Abstract
PURPOSE:To get rid of trouble such as improper contact, etc., and improve reliability by providing a limit switch having a conductive-rubber switch part which is switchingly operated by the pressurizing part of an operating lever and which restricts the rotating angle range of an output shaft. CONSTITUTION:A rubber conductive type limit switch does not carry out the direct ON/OFF control of a motor 1 but, instead, is inserted into, e.g., the base circuit of a motor driving transistor to carry out the ON/OFF control of a current thereof. And, the operation of ON/OFF is carried out by making pressurizing parts 31a, 31b provided on one end of each of operating levers 22a, 22b press or separate from switch parts 30a, 30b respectively at the time of operating by means of a limit lever 19. Hence, trouble such as improper contact and the like caused by the wear, deterioration, etc., of the contact of the limit switch can be removed to bring about high reliability.
