Problems solved by technology

[0002] Household appliances such as: mixers, meat grinders, juicers, etc. will be equipped with rotary switches. The existing rotary switches only have the function of rotating and shifting, and have no jog function. When household appliances such as mixers, meat grinders, and juicers are in use Usually, the inching function is used, and an additional inching switch needs to be added, resulting in complicated wiring, many original parts, and reduced electrical safety.

Abstract

The invention relates to the field of a wiring switch, and discloses a rotary switch. When a gear needs to be rotated, a rotary shaft is only required to be rotated; the rotary shaft drives a movable contact piece, which is arranged on the rotary shaft in a sleeving manner, to rotate; a rotary positioning apparatus is used for positioning the rotation of the rotary shaft and the movable contact piece; a rotary contact is in contact with a corresponding rotary contact piece on a chassis successively so as to realize electric connection and gear regulation; when inching control is needed, an inching contact is only required to be rotated to an inching contact piece; then inching electric connection between the inching contact and the inching contact piece is realized by pressing the rotary shaft; and therefore, the rotary switch is simple in wiring, less in components, and high in electric appliance safety.

Description

technical field [0001] The invention relates to the field of wiring switches, in particular to a rotary switch. Background technique [0002] Household appliances such as: mixers, meat grinders, juicers, etc. will be equipped with rotary switches. The existing rotary switches only have the function of rotating and shifting, and have no jog function. When household appliances such as mixers, meat grinders, and juicers are in use Usually the inching function is used, and an inching switch needs to be additionally added, resulting in complicated wiring, many original parts, and reduced electrical safety. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a rotary switch, which has the functions of rotary gear shifting and inching, simple wiring, few components and high electrical safety. [0004] The technical solution adopted by the present invention to solve its technical problems: [0005] A rotary sw...
