[0002] Switches are widely used in various electronic devices. Among them, the detection switch is a switch used to detect the parameters of the original or circuit. The detection switch has the advantages of small contact resistance, precise operating force error, and diversified specifications. The touch switch can also be used as a detection switch.

[0003] The Chinese utility model patent with authorization announcement number CN220585108U discloses a touch switch, which includes a base, a first terminal, a second terminal, a pot, an end cover and a button. When in use, the button is pressed, and the button presses the pot, causing the middle part of the pot to be compressed and elastically deformed, thereby connecting the first terminal and the second terminal.

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 4 As shown, a novel press detection switch includes an upper cover 10 and a base 20. The upper cover 10 is covered on the base 20. A button 30 is provided on the upper cover 10. A plurality of connection terminals 40 are provided on the sinking part 21 of the base 20. The connection terminals 40 are specifically embedded in the base 20.

[0019] The base 20 is provided with a contact piece 50 and a spring piece 60, a spring 70 is provided between the button 30 and the spring piece 60, the contact piece 50 is provided between the spring piece 60 and the base 20, and the contact piece 50 is located above the sinking part 21 of the base 20, the contact piece 50 is provided with an opening part 51 corresponding to the elastic part 61 of the spring piece 60, and the opening part 51 is provided with a plurality of contact finger pieces 52 for contacting with the connection terminal 40. The elastic part 61 of the spring piece 60 is specifically provided in the middle of the spring piece 60, and the opening part 51 of the contact piece 50 is also correspondingly provided in the middle of the contact piece 50.

[0020] As attached Figure 4 As shown, the terminal 40 is specifically divided into four parts, namely the first terminal 41, the second terminal 42, the third terminal 43, and the fourth terminal 44. The contact finger portion 52 of the contact piece 50 specifically includes a first contact finger portion 521 corresponding to the first terminal 41, a second contact finger portion 522 corresponding to the second terminal 42, a third contact finger portion 523 corresponding to the third terminal 43, and a fourth contact finger portion 524 corresponding to the fourth terminal 44.

[0021] Since the upper cover 10 is made of metal, in order to prevent the risk of electric shock, a PI film 80 is provided between the spring 70 and the spring sheet 60 to insulate the spring 70 from the spring sheet 60 .

[0022] The upper cover 10 is provided with a straight tube portion 11, and a limiting flange portion 12 is provided in the straight tube portion 11. The button 30 is slidably arranged on the straight tube portion 11 of the upper cover 10, and a limiting edge portion 31 is provided at the button 30 to cooperate with the limiting flange portion 12. The press detection switch also includes a shell 90 for fixing the upper cover 10 and the base 20, and the shell 90 is provided with a clamping foot portion 91 for clamping the base 20.

[0023] When using, combine with Figure 1 and attached Figure 3 As shown, the button 30 is pressed downward, and the button 30 drives the spring 70 to be pressed downward. The spring 70 also presses the spring piece 60 downward while undergoing elastic deformation. The elastic portion 61 of the spring piece 60 presses the first contact finger portion 521, the second contact finger portion 522, the third contact finger portion 523, and the fourth contact finger portion 524 of the contact piece 50 downward. The first contact finger portion 521 contacts the first terminal 41, the second contact finger portion 522 contacts the second terminal 42, the third contact finger portion 523 contacts the third terminal 43, and the fourth contact finger portion 524 contacts the fourth terminal 44, thereby achieving the connection between the first terminal 41, the second terminal 42, the third terminal 43, and the fourth terminal 44.

[0024] When the button 30 is released, the spring 60 and the spring 70 both restore their elastic deformation, and the spring 70 lifts the button 30 to reset it, and the first contact finger 521, the second contact finger 522, the third contact finger 523, and the fourth contact finger 524 of the contact piece 50 lose the pressure of the spring 60 and reset, thereby releasing the connection state between the first terminal 41, the second terminal 42, the third terminal 43, and the fourth terminal 44. The utility model can be applied to the case where there are a large number of terminals, and multiple terminals can be connected by pressing once, and it has the effect of pressing and mute.
