Abstract: A detector switch is provided to confirm that an electric signal from the controller to the electromagnetic valve is transformed into the operation of a control valve spool when the speed of an automobile or a construction machine is changed through a transmission. Therefore, the control valves (11, 12, 13) are provided with the detector switch (7) that is capable of transmitting a signal to the controller (5) when a valve spool (3) has come in contact therewith in a transmission that has the spool (3) for switching the electromagnetic valves (21, 22, 23) connected to the controller (5) to change the clutch hydraulic pressure to change the speed.
