[0001] The present application relates to the technical field of electrical switches, and more specifically, to a push-type switching switch. Background Art
[0002] The electrical switch plays a very important role in the circuit. Its main function is to control the on and off of the circuit so that the current flows or stops flowing in the circuit, thereby realizing the switch operation of the electrical equipment. In the related art, a switch can usually only realize the control of the start and stop of one electrical appliance or the control of the simultaneous start and stop of multiple electrical appliances. When it is necessary to control two groups of electrical appliances for switching, two switches are usually required. For example, electrical appliance group A is controlled by switch A, and electrical appliance group B is controlled by switch B. Electrical appliance group A and electrical appliance group B include at least one electrical appliance. When electrical appliance group A and electrical appliance group B are switching, it is necessary to operate switch A first to start electrical appliance group A, and then operate switch A to turn off electrical appliance group A after electrical appliance group A is operated, and then operate switch B to start electrical appliance group B, and then operate switch B to turn off electrical appliance group B after electrical appliance group B is operated. In this way, electrical appliance group A and electrical appliance group B are switched back and forth. When fast switching of electrical appliance group A and electrical appliance group B is required, the above technology has many steps, is troublesome to operate, and is not fast enough.

The first contact point is always in contact with the basic static contact piece through the movement of the rubber handle. When the rubber handle is limited at the top end of the sleeve, the first avoidance groove avoids the second contact point, and the third contact point abuts against the second switching static contact piece so that the second switching static contact piece and the basic static contact piece form a conductive circuit. When the rubber handle moves toward the bottom end of the sleeve, the second avoidance groove avoids the third contact point, and the second contact point abuts against the first switching static contact piece so that the first switching static contact piece and the basic static contact piece form a conductive circuit.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0024] Reference Figure 1 , Figure 2 and Figure 3A push-type switching switch includes a sleeve 1, which includes a sleeve 1 body, a bottom cover 12 and a top cover 13. The sleeve 1 body is in a rectangular shape and has a rectangular inner hole. The bottom cover 12 is arranged at the bottom end of the sleeve 1 body and closes the bottom port of the inner hole of the sleeve 1 body. The top cover 13 is detachably arranged at the top of the sleeve 1 body and closes the bottom port of the inner hole of the sleeve 1 body. Static contact pieces 2 are arranged on the opposite side walls of the inner hole of the sleeve 1 body. Each group of static contact pieces 2 includes a basic static contact piece 21, a first switching static contact piece 22, and a second switching static contact piece 23 arranged vertically at intervals on the side walls of the inner hole of the sleeve 1 body. The basic static contact piece 21, the first switching static contact piece 22, and the second switching static contact piece 23 all extend downward to the bottom cover 1. 2 and the bottom ends of the basic static contact piece 21, the first switching static contact piece 22 and the second switching static contact piece 23 are all provided with pins penetrating the bottom cover 12, a rubber handle 3 is movably provided in the inner hole of the sleeve 1 body, an elastic reset member 4 is provided between the rubber handle 3 and the bottom cover 12 to support the rubber handle 3 and reset the rubber handle 3, the rubber handle 3 includes a fixing portion 32 and a pressing portion 31 arranged at the top of the fixing portion 32, the fixing portion 32 is a rectangular parallelepiped matching the shape of the inner hole of the sleeve 1 body, the top cover 13 is provided with an opening 131 for the pressing portion 31 of the rubber handle 3 to pass through the sleeve 1 body, and moving contacts 5 are fixed on opposite sides of the fixing portion 32 of the rubber handle 3, the two moving contacts 5 correspond to the positions of the two static contact piece assemblies 2 respectively, the basic static contact piece 21, the first switching static contact piece 22 and the second switching static contact piece 23 The switching static contact piece 23 and the moving contact piece 5 are both made of conductive metal materials, and each moving contact piece 5 is provided with a first contact point 51, a second contact point 52, and a third contact point 53 that are in the same straight line. A first avoidance groove 221 is provided on the top of the first switching static contact piece 22, and a second avoidance groove 231 is provided on the second switching static contact piece 23 corresponding to the first switching static contact piece 22 at a position below the first avoidance groove 221. The first contact point 51 is always in contact with the basic static contact piece 21 through the movement of the rubber handle 3. When the fixed part 32 of the rubber handle 3 abuts against the top cover 13, the first avoidance groove 221 avoids the second contact point 52, and the third contact point 53 abuts against the second switching static contact piece 23 so that the second switching static contact piece 23 and the basic static contact piece 21 form a conducting circuit, and the rubber handle 3 is used to prevent the second switching static contact piece 23 from contacting the basic static contact piece 21. When the handle 3 moves toward the bottom cover 12, the second avoidance groove 231 avoids the third contact point 53, and the second contact point 52 abuts against the first switching static contact piece 22 to form a conducting circuit with the first switching static contact piece 22 and the basic static contact piece 21. The electrical appliances are connected through the pins of the basic static contact piece 21, the first switching static contact piece 22, and the second switching static contact piece 23. The conducting circuit formed by the basic static contact piece 21 and the first switching static contact piece 22 is used to connect one group of electrical appliances, and the conducting circuit formed by the basic static contact piece 21 and the second switching static contact piece 23 is used to connect another group of electrical appliances. By pressing the rubber handle 3, the conductive path formed by the basic static contact piece 21 and the first switching static contact piece 22 is disconnected and the conducting circuit formed by the basic static contact piece 21 and the second switching static contact piece 23 is realized.The elastic reset member 4 drives the rubber handle 3 to reset, thereby realizing the conductive path formed by the basic static contact piece 21 and the first switching static contact piece 22 and realizing the disconnection of the conductive circuit formed by the basic static contact piece 21 and the second switching static contact piece 23. The rubber handle 3 is limited at both ends of the sleeve 1, so that the contact point on the moving contact piece 5 can be accurately abutted against the corresponding position of the static contact piece. The power-off and power-on control of the two groups of electrical appliances are integrated in one switch. The switching operation of the two groups of electrical appliances is realized by pressing the rubber handle 3, which is convenient to operate and fast to switch. Furthermore, since the current for a group of static contact pieces 2 and a moving contact piece 5 to realize conduction is limited, the two-column static contact piece assemblies 2 and the corresponding two moving contact pieces 5 are provided to help control more electrical appliance groups to work simultaneously.
[0025] Reference Figure 3 The movable contact piece 5 includes a fixed sheet body 54 and a first contact foot 55, a second contact foot 56, and a third contact foot 57 that are bent upward and extend to one side of the fixed sheet body 54 and are arranged at intervals, and the angles between the first contact foot 55, the second contact foot 56, and the third contact foot 57 and the fixed sheet body 54 are all 120°, the first contact point 51 is set at the top of the first contact foot 55, the second contact point 52 is set at the top of the second contact foot 56, and the third contact point 53 is set at the top of the third contact foot 57. The first contact point 51, the second contact point 52, and the third contact point 53 are on the same straight line. The plastic handle 3 is formed by injection molding. The fixing sheet 54 is fixed to the fixing portion 32 of the rubber handle 3 by wrapping it with glue during the molding process of the rubber handle 3, and the fixing effect is good. When the fixing sheet 54 is fixed to the fixing portion 32 of the rubber handle 3, the first contact foot 55, the second contact foot 56, and the third contact foot 57 are facing the pressing portion 31 of the rubber handle 3, and the angle between the first contact foot 55, the second contact foot 56, and the third contact foot 57 and the side wall of the fixing portion 32 of the rubber handle 3 is 30°. This design is beneficial for the first contact foot 55, the second contact foot 56, and the third contact foot 57 to ensure that other parts except the contact point avoid the static contact piece assembly 2.
[0026] Reference Figure 3The opposite side walls of the inner hole of the sleeve 1 body are recessed with a first mounting groove 111, a second mounting groove 112, and a third mounting groove 113 arranged at intervals. The basic static contact piece 21 is arranged in the first mounting groove 111 and its exposed surface is flush with the inner hole wall of the sleeve 1 body. The first switching static contact piece 22 is arranged in the second mounting groove 112 and its exposed surface is flush with the inner hole wall of the sleeve 1 body. The second switching static contact piece 23 is arranged in the third mounting groove 113 and its exposed surface is flush with the inner hole wall of the sleeve 1 body. On one side wall of the inner hole of the sleeve 1 body, the second mounting groove 112 is located on the left side of the first mounting groove 111, and the third mounting groove 113 is located on the right side of the first mounting groove 111. The second mounting groove 112 on the other side wall of the inner hole of the tube body 1 is located on the right side of the first mounting groove 111, and the third mounting groove 113 is located on the left side of the first mounting groove 111. Accordingly, the first contact foot 55, the second contact foot 56, and the third contact foot 57 on both sides of the fixed portion 32 of the rubber handle 3 need to be arranged corresponding to the positions of the first mounting groove 111, the second mounting groove 112, and the third mounting groove 113. There are multiple options for the arrangement of the first mounting groove 111, the second mounting groove 112, and the third mounting groove 113. This embodiment only lists one of them. The use of the mounting groove to install the static contact piece so that the static contact piece is flush with the inner hole wall is conducive to smoother contact between the contact point on the contact foot and the static contact piece when the rubber handle 3 moves.
[0027] Reference Figure 2 and Figure 3 Furthermore, the elastic reset member 4 is a spring, and the bottom cover 12 is arranged on the support column 121. The bottom end of the spring is inserted into the support column 121 to be limited. The bottom surface of the fixing portion 32 of the rubber handle 3 is concavely provided with a receiving groove 321, and the top end of the spring is inserted into the receiving groove 321 to be limited. The rubber handle 3 is reset by storing pressure and releasing pressure through the spring. The process is relatively fast, which is conducive to speeding up the efficiency of switching the two groups of electrical appliances. The support column 121 and the receiving groove 321 limit the spring, reducing the situation where the rubber handle 3 is not accurately returned due to the spring deviation, so that the contact point cannot be in place.
[0028] Reference Figure 2 and Figure 3Furthermore, a convex ring 114 surrounding the interior is provided on the top of the sleeve 1 body, and a coupling groove 132 matching the convex ring 114 is concavely provided on the bottom surface of the top cover 13. The top cover 13 is inserted into the convex ring 114 through the coupling groove 132 to be limited. Buckles 115 are provided on the two opposite outer walls of the sleeve 1 body, and buckle plates 133 are provided on the opposite sides of the bottom surface of the top cover 13 extending downward. The side walls of the two buckle plates 133 are provided with buckle bodies 115 matching the buckle bodies 115. The buckle plate 133 is a thin plate with a specific elastic deformation capacity. The convex ring 114 is used to limit the top cover 13 so that the top cover 13 is accurately installed. The buckle plate 133 is limited by the buckle body 115 inserted into the buckling groove 1331 to move, thereby realizing the detachable fixation of the top cover 13 and the sleeve 1 body, which is convenient for installing the static contact piece group, the rubber handle 3 and the spring.
