A humidifier including a base defining a reservoir for retaining a liquid volume having an upper surface; a humidification unit removably mounted on the base and having an electrically energized humidifier adapted to induce dispersion of liquid retained by the reservoir, and a switch adapted in an active condition to energize the humidifier and in an inactive condition to cause deenergization thereof; and an actuator retained by the base and adapted for movement between activating and inactivating positions with respect to the switch, the actuator adapted in its activating positions to actuate the switch into its active condition and in its inactivating positions to actuate the switch into its inactive condition and wherein both given changes in the level of the upper surface and movement of the humidification unit relative to the base produce the controlling movement of the [actuator] switch. Mounting of a switch on a removable humidification unit and an actuator for the switch in a base supporting the unit facilitates desired shut-off in response to either an inadequate water supply or removal of the unit.
