A faucet has a main body, a cold water control device mounted onto a first end of the main body, a hot water control device mounted onto a second end of the main body and an outlet device mounted onto a top of the main body. The cold water control device selectively guides cold water flowing into the main body and flowing out from the outlet device. A drive device is laterally mounted onto the hot water control device for driving the hot water control device to selectively guide hot water flowing into the main body and flowing out from the outlet device. The drive device has a first magnet secured to a tube in a casing of the drive device and a second magnet disposed on a clutch shaft of the drive device to provide a repelling force for the clutch shaft.
