PURPOSE: To facilitate operation and prevent malfunctioning by enabling clutch connection only when a stroke switch turns ON in response to each operation of a transmission shift lever for an automobile being provided in such a manner as to be turned ON by pushing or pulling of the lever.
CONSTITUTION: When a shift lever is pushed through a shift knob, nozzle switches are turned ON at D and F and OFF at E. When the shift stroke of the shift lever exceeds 80%, a mobile contact piece 73 of a stroke switch 56 slides in contact with fixed contact pieces 64 and 66 to turn on a switch A. A common contact 136 is grounded through a series circuit with a switch E of the knob switch 78 to actuate an electromagnetic valve 100 causing an actuator 25 to shift a clutch 12 to be connected to first speed. Likewise, in response to pulling of the shift from the first to the second speed, a switch B works. This can facilitate the operation and prevent malfunctioning.
