Abstract: A dispenser for discharging pharmaceutical liquids in the form of individual drops, having a liquid store, a pump device with a pump chamber with a variable volume, and a dispensing opening. The dispenser additionally has a membrane part which delimits the pump chamber on one side and which changes the volume of the pump chamber by moving and/or deforming. The dispenser has a housing, within which the pump device is provided, and an actuation button movable relative to the housing between a non-actuated starting position and an actuated end position to move or deform the membrane part and to decrease the size of the pump chamber to discharge the liquid. The membrane part is secured to the housing and to the actuation button. The pump chamber achieves a high degree of compression and a toggle switch is used as the actuation button.
