Abstract

A screw rod with a push rod connected at two sides respectively is set up in the switch. A moving metal piece is setup at the upper part of two sides of the screw rod respectively. The fixed metal pieces are installed near the said moving metal pieces. There is ball groove with the spring and ball at the two sides of the screw rod. Corresponding hole are setup at the lower part of the moving metal piece. The invented switch can be installed in present plug with three pins without need of modifying sockets, providing the features of small operating force and size, good hand feeling. Cataphracted or coarse surface of the switch can be manufactured to make switch stable in sockets and easy of operation.

Description

technical field [0001] The invention relates to a switch, in particular to a screw power switch. Background technique [0002] The existing power switch is usually mechanically closed by a spring directly on the power supply metal sheet, which has a complex structure, large suddenness, large vibration, large mechanical loss, and laborious. Although the knife switch has no spring, it has a large area and cannot be completely closed, and it consumes the same force. Contents of the invention [0003] The purpose of the present invention is to provide a screw power switch, which can be switched easily. [0004] The technical scheme of the present invention is: a spiral power switch, a screw rod is arranged inside the switch, a push rod is connected to both ends of the screw rod, a movable metal sheet is provided on the inner upper ends of the spiral on both sides of the screw rod, and a movable metal sheet is arranged beside the movable metal sheet. There are fixed metal she...
