The first conductive elastic member 3 is capable of conducting electricity, has a certain elasticity, and can be deformed under pressure. The first conductive elastic member 3 can be installed at the edge of the circuit board in the circuit board mechanism 2, so that the first conductive elastic member 3 can abut against the conductive component after the circuit board mechanism 2 is installed in the housing mechanism 1, for example, the first conductive elastic member 3 is inserted and welded at the edge of the circuit board, thereby ensuring the connection firmness between the first conductive elastic member 3 and the circuit board. After the water output device is assembled, the first conductive elastic part 3 and the conductive part are abutted to each other to realize the electrical connection between the first conductive elastic part 3 and the conductive part.

In this way, the key 14 can be easily detached from the key mounting member 13 without any other fixed connection therebetween.

In order to improve the aesthetic appearance of the water delivery device, the second conductive elastic member 6 may abut against the inner wall of the button 14 when the button 14 is mounted on the button mounting member 13.
