Description

Rotary push switch

This creation is about a switch, especially a rotary push switch for controlling power or signal transmission.

Push switches have a wide range of applications, often used in electronic products, tools, vehicles or industrial equipment to control the transmission loop of power or signals. This type of switch is usually made by the user pressing the button. Alternately switch to the on state (ON) / off state (OFF).

However, it is difficult for the existing push switch to easily determine whether it is in the on state or the off state based on its appearance. Although some key parts of the push switch change their exposed height with whether they are pressed or not, the height of the key part changes very slightly, and it is not easy for the user to visually judge. Therefore, it is still quite inconvenient for the user in actual application.

In view of this, the main purpose of this creation is to provide a "rotary push switch" that can easily determine the on-off state of the switch.

The rotary push switch of this creation contains:

A base is provided with a first conductive terminal, a second conductive terminal, and a third conductive terminal. One ends of the first conductive terminal and the second conductive terminal extend outward from a front side of the base. One end of the three conductive terminals extends outward from a rear side of the base;

A conductive elastic piece, one end of which is fixed in the base and electrically contacted with the third conductive terminal, and the other end is elastically contacted with the second conductive terminal;

A top seat is correspondingly combined with the base, wherein a ring seat is provided on a top surface of the top seat;

A button assembly is arranged in the ring seat of the top seat to push the conductive elastic sheet to make electrical contact with the second conductive terminal or separate from the second conductive terminal. The button assembly includes a rotatable A pressing piece, on which a plurality of on-marks and open-circuit marks are arranged alternately;

A pressing cover is movably clamped on the top seat to relatively abut the key assembly so that the key assembly pushes the conductive elastic sheet, wherein a display window is provided on a top surface of the pressing cover, when the conductive elastic sheet When in electrical contact with the second conductive terminal, the display window corresponds to one of the conductive marks of the pressing member. When the conductive spring and the second conductive terminal are separated from each other, the display window corresponds to one of the pressing members. Open circuit mark.

By repeatedly pressing the pressing cover, the rotary pressing switch can alternately switch to the on state or the off state. When the rotary push switch is in the on/off state, the key assembly just turns the on/off mark to the corresponding display window, and the user can observe the on or off mark displayed in the display window to quickly determine switch status.

The rotating sleeve 34 is lifted by the upward pushing force of the abutting spring 35, and the abutting spring 35 is restored to its original shape from a compressed state. Since the conductive elastic piece 40 is no longer subjected to the pressure of the abutting spring 35, the upper contact 41 will be separated from the lower contact 121 to form a disconnection. The conductive elastic piece 40 is located at the disconnection position, and the rotary push switch 1 is Maintain the disconnected state.

When the pressing cover 50 is pressed by the user again, the rotary pressing switch 1 will switch from the off state (OFF) to the conducting state (ON) as shown in FIGS. 6A to 6C, wherein the driving sleeve 33 is pressed down Push against the oblique teeth 342 of the rotating sleeve 34 to cause the rotating sleeve 34 to rotate. As shown in FIG. 6C, when the blocking block 343 of the rotating sleeve 34 rotates along the chute 222 to resist the inclined blocks 223 After that, the locking block 343 of the rotating sleeve 34 and the protrusion 331 of the driving sleeve 33 are roughly in staggered positions, and the abutting spring 35 inside the rotating sleeve 34 is maintained in a compressed state and presses the conductive elastic piece 40 downward. Make the upper contact 41 of the conductive spring 40 contact the lower contact 121 correspondingly.

Please refer to FIG. 8, every time the pressing cover 50 is pressed to drive the rotating sleeve 34 to rotate, the rotating sleeve 34 also drives the pressing member 31 to rotate, causing the conduction mark 311 and the open circuit on the pressing member 31 The mark 312 is sequentially rotated to the position corresponding to the display window 52. When the rotary push switch 1 is in the on state, the conduction mark 311 on the push member 31 corresponds to the display window 52; when the rotary push switch 1 is off In the state, the open circuit mark 312 on the pressing member 31 exactly corresponds to the display window 52. Therefore, for the user, it is convenient to observe from the display window 52 whether the switch is currently in the on state or in the off state.

Please refer to FIG. 9. The structure of the first conductive terminal 11 to the third conductive terminal 13 of the present creation can be changed according to requirements. For example, in the embodiment of FIG. 9, the first conductive terminal 11 and the second conductive terminal 12 It can have a clamping part, and the clamping part is used to electrically connect with the corresponding power connector.

Please refer to the circuit diagram shown in FIG. 10 to illustrate the practical application of the rotary push switch 1. The first conductive terminal 11 and the second conductive terminal 12 are respectively connected to two ends of a power source S; one end of the load device L passes through the base 10 The opening 14 is electrically connected to the first conductive terminal 11, and the other end of the load device L is electrically connected to the third conductive terminal 13. Because the button assembly 30 can determine a path or an open circuit between the third conductive terminal 13 and the second conductive terminal 12, when the rotary push switch 1 is in the on state, the load device L and the power source S can form a complete power supply Loop to obtain power.

To sum up, by pressing the pressing cover 50, it can alternately switch to the on state or the disconnected state, and through the display window 52 on the pressing cover 50, the user can conveniently adjust the pressure on the pressing member 31 The continuity mark 311 or the disconnection mark 312 determines that the current state is on/off (ON/OFF).
