<p>A water tank has a container (20), a microswitch (30), a limiting assembly (40) and a float (50). The float (50) is mounted slidably in the container (20). The limiting assembly (40) has an actuating rod (41) that slides in a direction perpendicular to the sliding path of the float (50). An inclined guiding track (42) is mounted between the float (50) and the actuating rod (41) to convert the moving direction. Since the actuating rod (41) utilizes the movement to switch the micro switch (30) on and off, the actuating rod (41) and the micro switch (30) need no abutting structures. When the actuating rod (41) is moved by an accidental force, the actuating rod (41) self-moves back to its original position once the accidental force is removed, then the microswitch (30) is switched on again so that the household appliance is restarted.</p> |
