NZ738609B2 - Transmission device for push-button switch, push-button switch and socket - Google Patents

Abstract

push-button switch needs an indication means to indicate the operation state of the push-button switch. However, the driving of the indication means for the push-button switch in the prior art is complicated and has a large number of parts. The embodiments of the present disclosure provide a transmission device, including: a transmission means, configured to indicate operation states of a push-button switch by exposing an indication part of the transmission means; and an elastic means for driving the transmission means, disposed between the transmission means and a rocker of the push-button switch and configured to be deformed in responding to a pushing of a push button of the push-button switch, so as to drive the transmission means to move between a first predetermined position and a second predetermined position, in which, the first predetermined position corresponds to an on state of the push-button switch and the second predetermined position corresponds to an off state of the push-button switch. The embodiments of the present disclosure also provide a push-button switch and a socket. With the transmission device, the push-button switch and the socket according to the embodiments of the present disclosure, the transmission means is driven to move through the elastic force generated when the push button is pressed. The number of parts is small and the structure is simple.

Claims (12)

1. A transmission device for a push-button switch, comprising: a transmission means comprising a driving part and configured, in responding to a pushing action to the push-button switch, to drive, by the driving part, a rocker of the push-button switch to pivot, wherein, the transmission means further comprising an indication part for providing an indication function of indicating operation states of the push-button switch; and an elastic means for driving the transmission means, disposed between the transmission means and the rocker of the push-button switch and configured to deform in responding to a pushing to a push button of the push-button switch, so as to drive the transmission means to move between a first predetermined position and a second predetermined position, wherein, the first predetermined position corresponds to an on state of the push-button switch and the second predetermined position corresponds to an off state of the push-button switch, and wherein the elastic means drives the transmission means, which comprises the indication part, to move between the first predetermined position and the second predetermined position through a restoring force of the elastic means.

2. The transmission device according to claim 1, wherein, the elastic means is configured in a following manner: in the case that the transmission means is in the first predetermined position, when the push button of the push-button switch is pushed to actuate the push-button switch, the elastic means is deformed, and the transmission means is maintained in the first predetermined position and not moved; when the push button of the push-button switch is released, the transmission means is driven to move to the second predetermined position through the restoring force of the elastic means, so as to change a state indication of the push-button switch; in the case that the transmission means is in the second predetermined position, when the push button of the push-button switch is pushed to actuate the push-button switch, the elastic means is deformed, and the transmission means is maintained in the second predetermined position and not moved; when the push button of the push- button switch is released, the transmission means is driven to move to the first predetermined position through the restoring force of the elastic means, so as to change the state indication of the push-button switch.

3. The transmission device according to claim 1, wherein, the transmission means is slidably mounted to the push button of the push-button switch.

4. The transmission device according to claim 3, wherein, the indication part is disposed on a top surface of the transmission means, the push button has an opening window provided in a predetermined position, and when the indication part is slid to the predetermined position, the indication part is exposed out of the opening window, so that the operation state of the push-button switch is observable to a user.

5. The transmission device according to claim 4, wherein, the transmission means and the push button comprise abutting parts fitted with each other, and the abutting parts promote deformation of the elastic means in the case that the transmission means is maintained in a corresponding predetermined position and not moved.

6. The transmission device according to any one of claims 1-5, wherein, the elastic means is configured to be further deformed in responding to a pivoting of the rocker, so as to produce a force adapted to push the transmission means when the push button is released.

7. The transmission device according to any one of claims 1-5, wherein, the elastic means is a spring whose two ends are attached to the transmission means and the rocker, respectively.

8. A push-button switch, comprising: a transmission device according to any one of claims 1-7; the push button a housing; 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 transmission means, such that a moving contact of the push-button switch is driven to pivot through the rocker, so as to contact or to be separated from a fixed contact of the push-button switch.

9. The push-button switch according to claim 8, wherein, the push button is provided with a sliding rail, and the transmission means is slidably mounted to the sliding rail.

10. The push-button switch according to claim 8, wherein, the rocker is provided with a spring seat, and an end of the elastic means is adapted to be accommodated in the spring seat.

11. The push-button switch according to claim 10, wherein, the rocker is divided into a first portion and a second portion, the second portion is provided with the spring seat, so as to divide the push-button switch into two parts, wherein, the first portion of the rocker, the moving contact and the fixed contact form an installation panel adapted to be mounted to a fixed wall, the push button, the transmission means, the elastic means and the second portion of the rocker form a cover separated from the installation panel, wherein the second portion of the rocker is mounted to a main body of the cover through a pivot shaft.

12. A socket, comprising a push-button switch according to any one of claims 9- 11 for controlling power-on and power-off of the socket.
