ABSTRACT:
A ceramic plate for stick operated core shaft of a faucet is mainly made up of a faucet body, a locking unit, a valve case, a mount seat, a control stick, a stick fixing mount, a fixing unit, an upper switch valve, a lower switch valve and a faucet handle wherein the control stick activated by the faucet handle is engaged with the upper switch valve via an actuating block of the control stick inserted to a linkage groove disposed at the top of the upper switch valve for regulating the discharge of cold/hot water. When the faucet handle is switched to the right, the control stick will move the upper switch valve to slide to the left till a curved switch groove of the upper switch valve covers on top of a cold water inlet hole of the lower switch valve for the discharge of cold water out of a water outlet hole of the lower switch valve. Meanwhile, hot water is discharged in the other way around when the faucet handle is switched to the left for the upper switch valve to slide to the right till the curved switch groove thereof covers on top of a hot water inlet hole and the water outlet hole thereof for hot water discharge in the habitual manner, preventing users from carelessly burning themselves by hot water.
