Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, in particular to a touch switch. Background Art

[0002] A touch switch is an electrical switch that operates by touching the button surface. When a person touches the button surface, the touch switch detects the touch signal through a sensor and converts it into an electrical signal for processing. Based on the processing result, the touch switch can control the on / off state of the circuit, thereby turning on and off devices such as lights and electrical appliances.

[0003] Traditional mechanical switches are usually composed of multiple mechanical components, with complex structures and prone to failure. In addition, the life of mechanical switches is usually affected by the wear and fatigue of mechanical components and has a certain life limit. Due to the inherent defects of the mechanical structure, the response speed of mechanical switches is slow. In addition, since the mechanical structure requires pressing the switch, it is difficult to make it waterproof. Utility Model Content

[0004] In view of this, an object of the present invention is to provide a touch switch to solve the above-mentioned problem.

[0005] Based on the above objectives, the present invention provides a touch switch, comprising:

[0006] The switch housing has a raised portion at the top, the housing is through-designed, and an external thread is provided at the outer circular end of the switch housing;

[0007] a fastening nut threadedly connected to the external thread;

[0008] A light-transmitting ring is provided on the inner side of the switch housing, wherein a touch surface is arranged in the light-transmitting ring;

[0009] An electrical control board is arranged in the switch housing, and connecting leads are arranged on the electrical control board.

[0010] As an optional implementation, the bottom of the switch housing is sealed and filled with waterproof resin.

[0011] Furthermore, the waterproof resin also wraps the connecting wire inside the switch housing.

[0012] As an optional implementation, an O-ring is sleeved on the switch housing, and the O-ring is located between the bottom of the raised portion and the top of the fastening nut.

[0013] As an optional implementation, the light-transmitting ring is transparent.

[0014] As an optional implementation manner, the touch surface is a plane or a concave surface with a depression in the middle.

[0015] The beneficial effects of the present invention are as follows: the bottom of the switch housing is sealed and filled with waterproof resin, and the resin also covers the connecting lead, and an O-ring is sleeved on the switch housing to achieve waterproofing of the touch switch. Since the resin also covers the connecting lead, the lead will not be easily pulled, and the connection point between the lead and the electrical control board is not easy to fall off.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0023] like Figure 1-Figure 2 As shown, a touch switch includes:

[0024] The switch housing 1 has a raised portion 11 at the top, the housing is through-type, and an external thread 12 is provided at the outer end of the switch housing 1;

[0025] A fastening nut 2 is threadedly connected to the external thread 12;

[0026] A light-transmitting ring 3 is provided on the inner side of the switch housing 1 , and a touch-pressing surface 4 is placed in the light-transmitting ring 3 ;

[0027] An electrical control board 5 is disposed in the switch housing 1 , and a connecting lead 6 is provided on the electrical control board 5 .

[0028] As an optional embodiment, the bottom of the switch housing 1 is sealed and filled with a waterproof resin 7 .

[0029] In this embodiment, the bottom of the switch housing 1 is sealed and filled with a waterproof resin 7, which also covers the connecting lead 6. An O-ring 8 is provided on the switch housing 1 to achieve waterproofing of the touch switch. Since the resin also covers the connecting lead 6, the lead is not easily pulled, and the connection point between the lead and the electrical control board 5 is not easily detached. The touch switch has a faster response speed than a mechanical switch, and the electrical control board 5, the connecting lead 6 and the touch panel 4 are electrically connected.

[0030] Furthermore, the waterproof resin 7 also wraps the connecting lead 6 in the switch housing 1;

[0031] In this way, the lead wire will not be easily pulled, and the connection point between the lead wire and the electrical control board 5 will not fall off easily.

[0032] As an optional embodiment, an O-ring 8 is sleeved on the switch housing 1, and the O-ring 8 is located between the bottom of the protrusion 11 and the top of the fastening nut 2;

[0033] In this way, when water from the outside tries to enter the interior of the device through the touch switch installed on the device, it will be blocked by the squeezed and deformed O-ring 8.

[0034] As an optional embodiment, the light-transmitting ring 3 is transparent;

[0035] In this way, the light-transmitting ring 3 can transmit the light emitted from the electrical control board 5 .

[0036] As an optional embodiment, the touch surface 4 is a plane or a concave surface with a depression in the middle;

[0037] In this way, you can choose a flat or concave surface according to your preference.
