1. An oral irrigator comprising
a first liquid container;
a nozzle outlet;
a pump driven by a drive to pump liquid from the liquid container to the nozzle outlet so that a liquid jet is emitted via the nozzle outlet;
a first switch configured to power the drive only when the first switch is actuated once and the oral irrigator is switched into an ON state and so that powering of the drive is stopped and the oral irrigator is switched into an OFF state when the first switch is actuated once again; and
a second switch configured to power the drive only while the second switch is continuously actuated by the user and powering is stopped when the second switch is released by the user,
wherein the first switch and the second switch are disposed at a distance from one another and configured to operate independently from one another,
wherein the second switch is configured to override the first switch when, prior to actuation of the second switch, the oral irrigator is in the ON state, and
wherein releasing the second switch after overriding the first switch stops powering of the drive.
