[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example:

[0023] Reference Figure 1-3, a one-button sequential micro switch rain cover, including a micro switch 4, also includes: a base 2, the base 2 is provided with a switch outlet 201 and a wire port 202, the micro switch 4 is installed in the base 2, the roller of the micro switch 4 extends out of the base 2 through the switch outlet 201, and the wiring harness of the micro switch 4 extends out of the base 2 through the wire port 202; a cover 1, connected to the base 2; a rain shield 5, installed in the base 2, the rain shield 5 is provided with an empty port matching the switch outlet 201, and the roller of the micro switch 4 can pass The rain shield 5 extends out through the air outlet and is used to prevent external rainwater from entering the base 2 through the switch outlet 201. A pad 3 is installed in the base 2. The rain shield 5 and the micro switch 4 are both installed on the pad 3. A hose connector 6 is connected to the wire outlet 202 to protect the wiring harness of the micro switch 4. A locking bolt 301 is installed on the pad 3. The locking bolt 301 is used to install the rain shield 5 on the pad 3. A mounting bolt 401 is installed on the micro switch 4 to install the micro switch 4 on the pad 3.
