Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0024] refer to figure 1 and figure 2 , a squeeze switch, including an ellipsoidal elastic capsule body 1, but the shape of the elastic capsule body 1 is not limited thereto. The elastic capsule is provided with a first cavity 11 and a second cavity 12 which communicate with each other, and the inside of the first cavity 11 is filled with conductive elastic colloid 2 . The second cavity 12 is relatively small, and the diameter of the first cavity 11 and the...

Abstract

The invention discloses an extrusion switch and a formula of a conductive elastic colloid for the same, relating to the field of an electric switch. The extrusion switch comprises an elastic capsule body, wherein a first cavity and a second cavity are arranged in the elastic capsule body and are communicated, the first cavity is filled with a conductive elastic colloid, the elastic capsule body is provided with two metal sheets, and the metal sheets are separated from each other, used for connecting a wire and exposed out of the second cavity. The formula of the conductive elastic colloid comprises the following constituents based on parts by mass: 60-70 parts of latex solution, 10-20 parts of silver-copper alloy powder, 5-10 parts of conductive carbon black and 5-10 parts of carbon nanofiber. By the extrusion switch, the conductive elastic colloid can be promoted to enter the second cavity by a user through an operation mode of extruding the elastic capsule body, the two metal sheets are connected, and the switch state is switched. The extrusion switch has the advantages of no mechanical fatigue problem, and can be operated at an arbitrary angle.

Description

technical field [0001] The invention relates to the field of electric switches, in particular to a squeeze switch and the formula of the conductive elastic colloid used therein. Background technique [0002] Existing common electrical switches usually rely on metal shrapnel and return springs to realize disconnection or closure of the circuit. The user can only operate the switch through a specific button or a pull wire, which is inconvenient to use. Moreover, due to the repeated deformation of the metal shrapnel and the return spring, mechanical fatigue is prone to occur, resulting in reduced sensitivity of the switch and even loss of function of the switch. Moreover, in the traditional mechanical switch, the metal shrapnel is exposed in the air, and the surface of the metal shrapnel is easy to oxidize and absorb dust, resulting in insensitivity or failure of the switch. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the...
