Embodiment 1

[0026] combine figure 2 with figure 1 ,

[0027] The insulating mounting cylinder 2 and the insulating housing 1 can be freely installed and disassembled through threaded fitting of the threaded pipe and the threaded hole, and the assembly is very simple and convenient.

[0028] Insulating housing 1 (can be a square cylindrical insulating housing 1 with openings at both ends, with a cylindrical insulating installation cylinder 2 on the top, a circular threaded hole 9 in the center of the top of the insulating housing 1, and an insulating installation cylinder 2 The bottom is provided with a threaded pipe 8 with a convex thread. The threaded pipe 8 and the threaded hole 9 are threaded to cooperate with each other. The insulating installation cylinder 2 is provided with a cylindrical moving contact 5 with a hemispherical bottom surface. The insulating housing 1 is fixed inside Two static contacts 4 which are not in contact with each other are installed.

[0029] When the mov...

Embodiment 2

[0031] There is a switch button 3 on the top of the moving contact 5, a return spring 6 is provided between the bottom surface of the switch button 3 and the threaded tube 8, the return spring 6 is coaxial with the moving contact 5, and the two static contacts 4 face the insulating shell 1 One end of the outside is provided with a connecting terminal 7, and a groove 10 corresponding to the bottom surface of the movable contact 5 is provided between the two static contacts 4 facing the threaded hole 9, and the movable contact 5 can fill the two static contacts after moving downward. Groove 10 of contact 4.

[0032] The moving contact and the static contact are in contact through the groove 10, and then they are connected to the external circuit through the terminal 7, that is, pressing the switch button 3 can drive the moving contact 5, and the moving contact 5 can be filled after moving down. The grooves 10 of the two static contacts 4 make the two static contacts 4 contact, a...

Embodiment 3

[0035] The insulating shell 1, the insulating installation cylinder 2, the switch button 3, and the threaded pipe 8 are all made of hard PVC plastic, which is durable, has good insulation performance, good corrosion resistance, and low cost. The insulating installation cylinder 2 and the threaded pipe 8 are integrated structure. The two static contacts 4, the connecting terminal 7 and the moving contact 5 are all made of copper alloy, and have a good conductive effect. The static contact 4 is fixed inside the insulating housing 1 by an adhesive. Return spring 6 is made of stainless steel, has good elasticity and good corrosion resistance.

[0036] At least the following beneficial effects can be achieved: the terminal 7 at the end of the two static contacts 4 of the light touch switch can be used to connect into the electrical circuit, and the user can press the switch button 3 to drive the movable contact 5, and the movable contact 5 After moving down, the grooves 10 of the...

Abstract

The invention discloses a light touch switch. A moving contact (5) can be driven through pressing a switch button (3), the moving contact (5) moves downwards and then can fill up a groove (10) betweentwo fixed contacts (4), and the two fixed contacts (4) are in contact, so that a whole circuit is in an on state. A user loosens the switch button (3) and then a return spring (6) rebounds to drive the moving contact (5) to lift, so that the whole circuit is in an off state. An insulating mounting cylinder (2) and an insulating shell (1) can be in screw-thread fit through a threaded pipe (8) anda threaded hole (9) to be freely installed and removed, so that assembly is very simple and convenient. The novel light touch switch is high in reliability and convenient to use, the return spring (6)of the moving contact (5) can be removed and replaced without a power failure, the light touch switch can be used for a long period of time, and corrective maintenance is facilitated.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a light touch switch. Background technique [0002] The light touch switch can be turned on by lightly pressing the switch button when in use, and the switch will be turned off when the hand is released. The internal structure of the light touch switch is realized by the spring of the metal shrapnel. Tact switches are generally used in electric equipment that adjusts height or inclination. The existing tact switch design is relatively traditional, and it is very troublesome to disassemble and inconvenient to maintain. When the tact switch is used for too long, the return part of the moving contact is prone to failure. The traditional tact switch is inconvenient to disassemble and repair or replace parts. Contents of the invention [0003] The object of the present invention is to propose a tact switch in view of the above problems, to overcome the traditional design of the...
