Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a European-style rocker switch. Background Art

[0002] Rocker switches are hardware products that are often used in daily life. They are generally used in household switches, computer speakers, water dispensers, etc. They are simple to operate and easy to use. A new type of European rocker switch is proposed in CN208548305U. The rocker switch (4) generally further includes an inner button, a moving contact piece assembly and a stationary contact piece assembly. The inner button can be rotatably installed in the base. The inner button has pressing arms symmetrically extending from both ends of its rotating connection. When one end of the rocker button is pressed down, the rocker button will press down the pressing arm at the corresponding end of the inner button and drive the inner button to rotate. The contact pressure portion provided in the middle of the inner button acts on the moving contact piece assembly and drives the moving contact piece assembly to disconnect or close with the stationary contact piece assembly. The above switch has the following defects: only through the coordinated operation of the rocker button and the end of the inner button, when the pressing arm of the inner button is extended longer, due to the limited swing amplitude of the long inner button, especially the smallest swing amplitude near the middle rotating connection part of the inner button (that is, the rocker principle: the swing amplitude at both ends of the rocker is large, and the swing amplitude near the middle hinge is small, and due to the limited swing space, the longer the rocker, the smaller its maximum limit swing angle), the long inner button is prone to the problem that the downward swing cannot trigger the contact closure, and if the touch-pressing part of the long inner button is raised, the overall thickness of the switch will be caused. Utility Model Content

[0003] The purpose of the utility model: in order to overcome the defects of the prior art, the utility model provides a European rocker switch, in which the two ends of the inner button can be shortened, and paddles are distributed at the two ends of the inner button. Under the same pressing stroke of the inner button, the short inner button has a larger swing amplitude. Under the condition of maintaining the original swing amplitude of the inner button, the downward pressing stroke of the paddle corresponding to the rocker button can also be shortened.

[0004] The technical solution of the utility model is as follows: a European-style rocker switch comprises a shell base, a panel and a rocker button located on the panel, a wire connection module and a switch module are arranged in the shell base, the switch module comprises an inner button and at least one group of contact assemblies, one group of contact assemblies has two pairs of moving and static contacts, the rocker button can drive the two ends of the inner button to swing up and down, so that the inner button triggers one pair of moving and static contacts to close and the other pair of moving and static contacts to disconnect, and plectrums are distributed at the two ends of the inner button, the middle part of the plectrums is hinged, and the two ends thereof are respectively a pressure-bearing head and a lifting head, the lifting heads of the two plectrums extend respectively to the lower parts of the two ends of the inner button, the two ends of the rocker button can respectively press the pressure-bearing heads of the two plectrums, and by pressing down the pressure-bearing head of the plectrum, the lifting head is rotated upward to lift up the corresponding end of the inner button.

[0005] By adopting the above technical solution, the two ends of the rocker button can press the pressure heads of the two paddles respectively. When one end of the rocker button is pressed down, the pressure head of one of the paddles will be pressed down to make the paddle rotate. The lifting head of the paddle rotates upward to lift the corresponding end of the inner button, so that the inner button swings to trigger a pair of moving and static contacts to close and the other pair of moving and static contacts to disconnect.

[0006] This product simultaneously installs an inner button and paddles distributed at both ends in a switch housing of fixed specifications, which will shorten the two ends of the inner button. The shorter the two ends of the inner button are, the greater the limit swing angle within the limited swing space. Since the swing amplitude of the short inner button is large enough, even if the contact and pressure part in the middle of the inner button is made thinner, it can act on the moving contact, so that the switch as a whole can be made thinner; and by adding a rotatable paddle to press the inner button, the rocker button is used to press the pressure head of the paddle, so that the swing amplitude of the outer end of the rocker button can be reduced.

[0007] Preferably, both ends of the inner button have pressing arms, and the lifting heads of the two dials have recesses for the pressing arms to extend into, and when the dials swing, the corresponding pressing arms are supported by the bottom walls of the recesses and lifted upward.

The upper end of the conductive sheet 1 71 has a bending head 711, and the bending head 711 is inclined to contact and conduct electricity on the bottom surface of the conductive sheet 2 72. The lower end of the conductive sheet 1 71 is also in contact with a static contact arm A for conduction, and the static contact arm A is connected to the wire connection module for conduction.
