NZ738694B2 - Transmission device for push-button switch, push-button switch and socket - Google Patents

Abstract

Embodiments of the present disclosure provide a transmission device, including a driving means and a transmission means for driving the driving means. The driving means includes a driving part and is configured, in responding to an action to the push button of the push-button switch, to drive, by the driving part, the rocker of the push-button switch to pivot rotate. The driving means further includes an indication part to provide a feature for indicating operation states of the push-button switch. The driving means is disposed in a manner of being clamped between the push button of the push-button switch and the transmission means. The transmission means is configured to pivot in a plane parallel to a pushing direction of the pushing button in responding to a pushing action or a releasing action of the pushing button, so as to drive the driving means to slide between a first predetermined position and a second predetermined position. The first predetermined position corresponds to an on position of the push-button switch and the second predetermined position corresponds to an off position of the push-button switch.

Claims (10)

1. A transmission device for a push-button switch, wherein the push-button switch comprises a push button, comprising: a driving means comprising a driving part and being configured, in responding to an action to the push button of the push-button switch, to drive, by the driving part, a rocker of the push-button switch to pivot, wherein, the driving means further comprising an indication part to provide a feature for indicating operation states of the push-button switch; and a transmission means for driving the driving means, the driving means being disposed in a manner of being clamped between the push button and the transmission means, wherein, the transmission means is configured to pivot in a plane parallel to a pushing direction of the pushing button in responding to a pushing action or a releasing action of the pushing button, so as to drive the driving means to slide between a first predetermined position and a second predetermined position, wherein, the first predetermined position corresponding to an on position of the push-button switch and the second predetermined position corresponding to an off position of the push-button switch, and wherein the driving part of the driving means is configured to engage with a first slave part of the rocker or a second slave part of the rocker to drive the rocker, wherein the first slave part and the second slave part are situated at respective ends of the rocker.

2. The transmission device according to claim 1, wherein the transmission means is pivotably mounted between the driving means and the rocker, and is connected to a sliding part through an elastic part, the sliding part is configured to slide along a slant surface of the rocker.

3. The transmission device according to claim 2, wherein the driving means is configured in following manners: in the case that the driving means is in the first predetermined position, when the push button is pushed, the driving means presses the first slave part, the elastic part is compressed, and when the push button is released, the elastic part drives the transmission means to pivot in a plane parallel to a pushing direction of the push button under action of the sliding part and the rocker, and drives the driving means to slide to the second predetermined position; in the case that the driving means is in the second predetermined position, when the push button is pushed, the driving means presses the second slave part, the elastic part is compressed, and when the push button is released, the elastic part drives the transmission means to pivot in the plane parallel to the pushing direction of the push button under action of the sliding part and the rocker, and drives the driving means to slide to the first predetermined position.

4. The transmission device according to claim 1, wherein the driving means is slidably accommodated in a cavity defined by side walls of the push button, and the driving means is configured to slide between the first predetermined position and the second predetermined position.

5. The transmission device according to claim 1, wherein the push button is provided with a display window.

6. The transmission device according to claim 5, wherein the driving means is provided with a feature for indicating the operation states of the push-button switch on a surface of the driving means facing the push button, so that the operating states of the push-button switch are observable to the user through the display window.

7. A push-button switch, comprising: a transmission device according to any one of claims 1-6; a housing; the push button provided with a display window; and the rocker pivotably mounted to the housing of the push-button switch and configured to pivot in responding to a downward movement of the push button, to drive a moving contact of the push-button switch to pivot through a contour portion of the rocker, so as to contact or to be separated from a fixed contact of the push-button switch.

8. The push-button switch according to claim 7, wherein the push button has a sliding rail, and the driving means is slidably mounted to the sliding rail.

9. The push-button switch according to claim 7 or 8, wherein the push-button switch is divided into two portions, the rocker, the moving contact and the fixed contact form an installation panel configured to be mounted to a fixed wall, the push button and the transmission device form a cover separate from the installation panel.

10. A socket, comprising a push-button switch according to any one of claims 7-9 for controlling power-on and power-off of the socket.
