An electronic device includes a housing, a support member coupled to the housing, a trigger member coupled to the support member, a sliding member, a first magnet member coupled to the sliding member, and a second magnet member coupled to the support member. The first magnet member includes two first magnets and a second magnet coupled to the corresponding first magnet. The magnetic pole of the first magnets is opposite to the magnetic pole of the second magnet. The second magnet member includes a third magnet and two fourth magnets. The magnetic pole of the third magnet is same as the magnetic pole of the second magnet. The magnetic pole of the fourth magnets is same as the magnetic pole of the first magnets.

Switch and folding structure thereof, and electronic device using the switch

An enclosed polishing apparatus include a housing, a fixing seat, a guiding mechanism, and a chain-driven polishing mechanism. The housing includes a bottom housing and a top housing connected to the bottom housing. The fixing seat is securely placed in the bottom housing. The guiding mechanism is placed in the top housing above the fixing seat. The polishing mechanism is movably mounted on the guiding mechanism above the fixing seat. The polishing mechanism is driven and guided by the guiding mechanism to follow a desired polishing contour on a workpiece.

Enclosed polishing apparatus

A device cover includes a bottom base and at least one sidewall extending from the bottom base. The at least one sidewall is formed by an upsetting process. The device cover is made of metal. Only one fold is formed by flow tracks of metallic grain of the at least one sidewall. A method for fabricating the device cover is also disclosed.
