Abstract

A rotary switch comprises an insulating base, an insulating cover plate, a rotating shaft, a spring button, a spring and a contact box; wherein, the end of the rotating shaft is provided with a rotary disk; a gear groove and a push part are arranged on the edge of the rotary disk; a spring box is arranged on the insulating base; a compression spring is arranged in the spring box; the spring button is arranged against the gear groove on the edge of the rotary disk through the spring force; a movable contact and a static contact are arranged in the contact box; an insulation button is arranged on the contact box; the insulation button connects or disconnects the movable contact and the static contact through the push part; a sector block is arranged on the insulating base; the bottom of the rotary disk is provided with two stop blocks which control the turning angle of the rotating shaft together with the sector block, and a knob is arranged on the other end of the rotating shaft. In the rotary switch, the movable contact and the static contact are arranged in the insulated contact box, thus being simple to implement and having the biggest advantage of maintaining good conducting channel in the moist environment, preventing creepage and having high safety performance.

Description

technical field [0001] The invention relates to a switch, in particular to a rotary switch. Background technique [0002] In the prior art, the rotary switch often sets the elastic static contact piece on the switch base, sets the moving contact piece on the switch shaft, and connects or disconnects the moving contact piece and the static contact piece by rotating the switch shaft. The moving contact piece and the static contact piece are often exposed in the switch seat, such as a rotary switch with a patent number of 00227395.0, which includes an upper cover, a lower case, a switch shaft, and a conductive sheet. The lower case is provided with a side wall belt. There is a tooth-shaped cavity with a tooth-like structure, and a disc-shaped positioning block is arranged on the switch shaft. The positioning block is arranged in the center of the tooth-shaped cavity, and can be positioned and rotated. The positioning block is provided with a through hole in the radial direction...
