Pressing-type electric switch

Abstract

The invention discloses a pressing-type electric switch. The pressing-type electric switch comprises a shell (1); a cross cavity is formed in the shell (1), a reset spring (3) is located at the bottomof a vertical cavity, and the lower end of a pressing column (2) is located in the vertical cavity and is contacted with the reset spring (3), and the upper end extends out of the upper port of the shell (1); the upper port of the shell (1) is provided with a limiting ring, and a limiting bulge (22) is arranged at the middle upper part of the pressing column (2) and in the vertical cavity; two ends inside a transverse cavity are provided with compression springs (5), conductive blocks (4) are arranged between the compression springs (5) and the pressing column (2), and the middle part of thepressing column (2) is a conductive part (21); two transverse ends of the shell (1) are provided with plug holes (6), each plug hole (6) is radially provided with a compression thread hole (7), the inner wall of the plug hole (6) is provided with a conductive layer, and the conductive layer is electrically connected with the conductive block (4). The electric switch in the invention is durable andhas a simple structure.

Description

technical field [0001] The invention belongs to the field of electrical appliances, and in particular relates to a push-type electric switch with simple structure and durability. Background technique [0002] At present, common electric switches in life have two states, on or off, and the electric switches can be kept on or off for a long time. In life, it is rare to see an electric switch that can only be kept in the off state unless it is operated by humans. Even if there is, the structure is either complicated or not durable. For example, in the flashlights used in the early days, a push-type switch was installed on the early flashlights. When the hand was pressed, it was in an open (electrically connected) state. As long as you let go, it will be closed immediately (electrically disconnected). Although this push-type switch has a simple structure, but It consists of two metal sheets arranged at intervals, at least one metal sheet has elasticity, which is achieved by pre...

It is rare to see an electric switch that can only be kept in the off state unless it is operated by humans all the time. Even if there is, the structure is more complicated or it is not durable

For example, in the flashlights used in the early days, a push-type switch was installed on the early flashlights. When the hand was pressed, it was in an open (electrically connected) state. As long as you let go, it will be closed immediately (electrically disconnected). Although this push-type switch has a simple structure, but It consists of two metal sheets arranged at intervals, at least one metal sheet has elasticity, which is achieved by pressing the metal sheet to make the two contact and relying on the elasticity of the metal sheet; after this kind of setting is used for a period of time, the metal sheet is not easy to reset, and it is easy to Lose the function of pressing the switch, the present invention is to solve this problem
