Description

Technical Field

[0001] The utility model relates to a wall switch. Background Art

[0002] The buttons of common household wall switches generally adopt a seesaw-type pressing structure, with the middle part of the button as the hinged rotation center, and the two ends of the button are pressed separately. In this way, no matter whether the switch is in the on or off state, one end of the button must be lifted higher than the plane of the switch panel. Especially when multiple buttons are adjacent and side by side, it is easy to touch the operation by mistake, and one end of each button is high and low, which is not neat and obviously affects the appearance. Now there are also self-reset switches, and the buttons can maintain a flat state with the switch panel, but the current self-reset switches have many internal parts and a complex structure. It is not easy to produce and assemble, and the reliability of use is not ideal. Summary of the invention

[0003] In view of the deficiencies of the prior art, the utility model provides a self-resetting wall switch which has a reasonable structure and is reliable in use.

[0004] The utility model comprises a key arranged on the front side of a shell frame, a static contact piece assembly is fixed inside the shell frame, one side of the key is hinged to the shell frame near the edge to form a pressing rotation center, a swinging piece and the key are arranged in the shell frame for linkage cooperation, a reset spring is connected to the swinging piece, a movable neutron piece and two ends of the swinging piece are correspondingly matched, a push rod is connected to the neutron piece, the end of the push rod and the conductive springboard are in dynamic contact cooperation, and the conductive springboard and the static contact piece assembly are in corresponding on-off contact cooperation.

[0005] The utility model has a reasonable structure, a small number of internal parts, and is easy to assemble. When in use, by pressing a button, the conductive springboard and the static contact piece assembly can be switched on and off. The button can reset itself and keep it flush with the surface of the wall switch without a raised end. It is not only neat and beautiful, but also avoids accidental touches and has high reliability for long-term use.

[0013] like Figures 1 to 4 As shown, the button 2 is arranged on the front of the shell frame 1, and one side of the button 2 is hinged to the shell frame 1 near the edge to form a pressing rotation center. A swinging member 4 is arranged in the shell frame 1 to cooperate with the button 2, and a reset spring 5 is connected to the swinging member 4, and a movable neutron member 6 and two ends of the swinging member 4 are correspondingly matched. The neutron member 6 is connected to a push rod 7, and the end of the push rod 7 is in dynamic contact with a conductive springboard 8, and the conductive springboard 8 and the static contact piece assembly 3 fixed inside the shell frame 1 are in corresponding on-off contact. In this embodiment, a movable linkage bracket 9 is provided between the swinging member 4 and the button 2, which can make the pressing linkage process smoother and the hand feel clearer.

[0014] When in use, the button 2 is pressed, and the hinged side of the button 2 is used as the rotation center and moves inward around the rotation center, and the linkage bracket 9 is driven together with the swing member 4, and the end of the swing member 4 shakes the neutron member 6 and the top rod 7, and the end of the top rod 7 drives the conductive springboard 8 to swing, switching the on-off contact state with the static contact piece assembly 3, such as Figure 5 In this embodiment, a small spring 10 is sleeved on the top rod 7, and the top rod 7 and the neutron part 6 are elastically and movably connected, so that the dynamic contact with the conductive springboard 8 is more stable and gentle, avoiding jamming and having higher reliability.

[0015] After the pressing force is removed, the reset spring 5 elastically recovers, causing the swing member 4 and the linkage bracket 9 to return to their original positions, pushing the button 2 to automatically return to a state flush with the switch panel. Figure 6 If the button 2 is pressed again, the conductive spring board 8 switches the on-off contact state with the static contact piece assembly 3, and returns to the on-off contact state after releasing the button 2. Figure 2 status, and so on.
