Description

Technical Field

[0001] The utility model relates to a light touch switch, in particular to a novel light touch switch which saves pad space. Background Art

[0002] A touch switch, also known as a push button switch, has an internal structure that relies on the force change of a metal spring (commonly known as a pot piece) to achieve on and off. The Chinese utility model patent with the authorization announcement number CN220585108U discloses a touch switch, which includes a base, a first terminal, a second terminal, a pot piece, an end cover and a button. The first terminal and the second terminal are arranged on the base in an interval manner, and the pot piece is arranged in the first inner cavity of the base, and the edge of the pot piece is in contact with the first terminal. Although the waterproof part of this structural design has good stability, since the first terminal and the second terminal are arranged in an outward expansion type, the size of the pad to which it is applicable is required to be larger, and the structural design of the touch switch needs to be further improved and simplified. To this end, we propose a new touch switch that saves pad space. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Combined with Figure 1 To Attachment Figure 3As shown, a novel touch switch for saving pad space includes a base 1, a first terminal 2, a second terminal 3, a pot piece 4, an end cover 5, and a button member 6 for pressing the pot piece 4, and a Figure 3 and attached Figure 4 As shown, the first terminal 2 and the second terminal 3 are arranged at intervals on the base 1, the pot piece 4 is arranged in the inner cavity of the base 1, the edge of the pot piece 4 is in contact with the first terminal 2, and the button member 6 is sandwiched between the base 1 and the end cover 5.

[0019] Combined with Figure 2 and attached Figure 4 As shown, the first terminal 2 includes a first end leg 21 and a second end leg 22, both of which are folded downward and folded toward each other; the second terminal 3 includes a third end leg 31 and a fourth end leg 32, both of which are folded downward and folded toward each other; the bottom of the base 1 is provided with a first groove 11, a second groove 12, a third groove 13, and a fourth groove 14 for accommodating the first end leg 21, the second end leg 22, the third end leg 31, and the fourth end leg 32, respectively. As shown in the attached Figure 2 As shown, the bending angles α of the first end leg 21 , the second end leg 22 , the third end leg 31 , and the fourth end leg 32 are all less than 90°.

[0020] Since the first end pin 21 and the second end pin 22 of the first terminal 2 are both folded downward and folded toward each other, the third end pin 31 and the fourth end pin 32 of the second terminal 3 are both folded downward and folded toward each other, the bending parts of the first end pin 21, the second end pin 22, the third end pin 31, and the fourth end pin 32 are slightly higher than the bottom of the base 1. Therefore, when the touch switch is welded on the pad, the bending parts of the first end pin 21, the second end pin 22, the third end pin 31, and the fourth end pin 32 can be directly welded to the pad.

[0021] Since the first end pin 21, the second end pin 22, the third end pin 31, and the fourth end pin 32 are all folded toward the bottom of the base 1 and stored in the first groove 11, the second groove 12, the third groove 13, and the fourth groove 14, compared with the existing touch switch in which the first terminal and the second terminal are arranged in an outward expansion type, the utility model can be applied to a smaller pad, thereby achieving the technical effect of saving pad space and reducing the material cost of the pad. In addition, the utility model can realize single-pole double-throw or single-pole single-throw, and the overall structural design is simpler.

[0022] Combined with Figure 3 and attached Figure 4As shown, the first terminal 2 is provided with a first contact point 201, the second terminal 3 is provided with a second contact point 301, and the two first contact points 201 are symmetrically arranged on the left and right sides of the second contact point 301. The first terminal 2 and the second terminal 3 are specifically integrally injection molded with the base 1.

[0023] Combined with Figure 3 As shown, the pot piece 4 is in the shape of a disk with a center protruding upward, the edge portion 42 of the pot piece 4 is placed on the first contact point 201 of the first terminal 2, and the center portion 41 of the pot piece 4 is suspended above the second contact point 301 of the second terminal 3.

[0024] The button member 6 is provided with a middle button portion 61 and an edge support portion 62. The middle button portion 61 protrudes outward from the middle hole 51 of the end cover 5, and the edge support portion 62 is sandwiched between the base 1 and the end cover 5. The base 1 is provided with a buckle tongue portion 15, and the end cover 5 is provided with a buckle portion 52 for matching with the buckle tongue portion 15. The button member 6 is specifically made of an elastic material (such as silicone).

[0025] When using the touch switch, press the middle button part 61 of the button member 6 downward, and the button member 6 presses down the central part 41 of the pot piece 4, so that the central part 41 of the pot piece 4 contacts the second contact point 301 of the second terminal 3. Since the edge part 42 of the pot piece 4 is placed on the first contact point 201 of the first terminal 2, when the central part 41 of the pot piece 4 contacts the second contact point 301 of the second terminal 3, the pot piece 4 connects the first terminal 2 with the second terminal 3, thereby turning on the touch switch.

[0026] When the middle button portion 61 of the button member 6 is released, the button member 6 resumes its elastic deformation, the central portion 41 of the pot piece 4 loses the downward pressure and bounces upward to the original height position again, disconnecting the connection between the first terminal 2 and the second terminal 3, thereby closing the touch switch.
