A faucet for dispensing beverages includes a valve element that is selectively moved from its seated position to its unseated position by manual linear movement of a handle in a first direction from a retracted position toward an extended position. Movement of the handle in the first direction induces movement of the valve element in the first direction. A shaft projects through the handle and an outer end of the shaft provides a reaction structure or button that is engaged by a thumb of a user during movement of the handle from its retracted position toward its extended position. When in its extended position, the handle can be rotated to a lock-open position where interference between the handle and the faucet body prevents movement of the handle from its extended position to its retracted position whereby the faucet is maintained in an opened condition for continuous dispensing of liquid.
