A kind of speed regulating switch with sudden jump function

Abstract

The invention relates to a speed regulating switch with a kick function, which comprises a shell, a movable frame and contact assemblies, wherein the movable frame and the contact assemblies are installed in the shell in a sliding mode; the contact assemblies include a moving contact component and a static contact component, the moving contact component is driven by the movable frame, and the movable frame is connected with the moving contact component through an elastic piece; a locking mechanism which is matched with the moving contact component is installed in the shell; the moving contact component is driven to move by the movable frame through the elastic piece; the locking mechanism is driven to unblock by the movable frame; and the moving contact component is driven to kick by the elastic piece. The speed regulating switch with the kick function has the beneficial effects that firstly, the kick function can be realized when the moving contact component of the speed regulating switch is disconnected or connected with the static contact component, the product sensitivity is increased, and the speed regulating switch can be safely and reliably used; and secondly, the speed regulating switch has the advantages of simple structure, less components and convenience in assembly, raw materials are saved, and the production cost of the product is reduced.

Description

technical field [0001] The invention relates to a speed regulating switch, in particular to a speed regulating switch with a sudden jump function. Background technique [0002] Most of the speed regulating switches include a shell in which a contact assembly and a speed regulating control circuit board are arranged. The on-off of the contact assembly is controlled by a manual lever extending from one end of the casing. The head assembly cannot realize instantaneous closing or opening, so the performance is not stable enough, and the life is short. It is difficult to pass the slow test in the switch life test, and the structure is complex and the assembly efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a speed regulating switch with a simple structure and capable of realizing the jump of the moving contact. [0004] According to the...
