Detailed Description

Example 1:

referring to fig. 1-6, a single-point waterproof push switch includes a combination switch housing 1, where the combination switch housing 1 is in a semicircular shape, and it should be noted that, the present application describes a housing provided with a switch on the combination switch, and another housing is connected to a rotating handle, and the two housings are connected in a splicing manner, and the other housing is irrelevant to the present application, so that it is not described in detail.

The combined switch comprises a combined switch shell 1, wherein a containing cavity 2 is arranged in the combined switch shell 1, a press switch 3 is arranged on the containing cavity 2, the included angle between the center of a button 4 of the press switch 3 and the circle center of the combined switch shell 1, which is connected with an imaginary line and a horizontal line, is A, the included angle is-60 degrees and is not more than-30 degrees, the included angle is preferably-55 degrees, the setting of the angle is adopted, the button 4 is positioned below one side of a rider, when rainwater or other liquid slides on the shell, due to the action of gravity, the rainwater or other liquid does not reach the button 4, and the rainwater or other liquid drops to the ground. A hook 21 and a guide groove 22 are arranged in the accommodating cavity 2.

The press switch 3 comprises a button 4, a button core 5, a mounting seat 6, a return spring 7 and a fixing seat 8, wherein the button 4 is movably fixed in the accommodating cavity 2, a protruding part 41 is arranged on the button 4, and the protruding part 41 is abutted to the inner wall of the accommodating cavity 2. The button 4 is provided with a concave cavity 42, a protrusion 421 is arranged in the concave cavity 42, and the concave cavity 42 is arranged towards the button core 5.

Be equipped with fixed slot 61, draw-in groove 62 and guide protrusion 63 on the mount pad 6, mount pad 6 slides in guide slot 22 through guide protrusion 63, then is fixed with trip 21 through fixed slot 61, realizes that mount pad 6 is fixed with combination switch casing 1. The mounting seat 6 here fits into the receiving cavity 2, forming a fixing. The end of the mounting seat 6 facing the push button 4 is provided with a projection 64 (i.e. on the top end of the mounting seat 6), the projection 64 exceeding the height of the mounting seat 6, where the projection 64 is mainly used for the protrusion of the button core 5.

Be equipped with buckle 81 on the side of fixing base 8, draw-in groove 62 realizes fixedly with the cooperation of buckle 81. The fixing base 8 is provided with a fixing column 82, a first conducting strip 83 and a second conducting strip 84, the first conducting strip 83 is sleeved on the fixing column 82 and extends out of the fixing base 8, and the second conducting strip 84 is fixed on the fixing column 82 and extends out of the fixing column 82. The second conductive sheet 84 is provided with a hemispherical contact 841 adapted to the movable contact of the button core 5.

One end of the button core 5 penetrates out of the boss 64 to be linked with the button 4, and is specifically matched with the protrusion 421, the other end of the button core 5 is provided with a movable contact 51, the movable contact 51 is hemispherical, and the button core 5 moves towards the hemispherical contact 841 on the second conducting strip 84 by pressing the button 4, so that the two are connected.
