Abstract: A bypass switch device with indicating function is disclosed. The bypass switch device is for use in a network appliance having at least one Ethernet network module, and comprises N switch units and a microcontroller. The microcontroller is configured to change the switching state of at least two said switch units in case the Ethernet network module fails to work normally, such that at least two RJ45 connectors directly communicate with each other through at least two said switch units. In such case, the microcontroller simultaneously controls one of two LED components included by one said RJ45 connector and one of two LED components included by another one said RJ45 connector, such that the two LED components emit lights for indicating that the Ethernet network module is working in a bypass mode.

Abstract: An airbrush includes a can, a cover, a spraying device and a blending device. The can includes an open upper end and an open lower end. The cover is connected to the open upper end of the can. The spraying device is mounted on the cover so that the spraying device is in communication of fluid with the can through the cover. The blending device is connected to the open lower end of the can and operable to blend paint contained in the can without having to open the can.
