Abstract: A water dispenser, which is for controlling a water flow of a water dispensation having a water outlet, includes a faucet adapted for mounting on a counter and an operating mechanism which includes a switch being supporting under the counter, a valve operatively linked to the switch for operatively mounting at the water outlet, and a hosting object magnetically connected to the switch when moving the hosting object on the counter. When the hosting object is moved to align with the switch, the valve is actuated at an opened position for allowing water to flow to the faucet. When the hosting object is moved away from the switch, the valve is actuated at a closed position for blocking the water to flow to the faucet.
