NZ738606B2 - Transmission device for push-button switch, push-button switch and socket - Google Patents

Abstract

Embodiments of the present disclosure provide a push-button switch including a transmission device, comprising: a transmission means (20), and the transmission means (20) includes an indication part (22) for providing an indication function of indicating operation states of a push-button switch. The transmission device further includes an elastic means (30) for driving the indication part (22) to move so as to provide the indication function. The elastic means (30) is disposed between the transmission means (20) and a rocker (40) of the push-button switch, extends in a plane perpendicular to a pushing direction, and comprises an opening (31) adapted to be fitted with a shaft (42) protruding from the rocker (40). The elastic means (30) is configured to move in responding to a pivoting of the rocker (40) of the push-button switch, so as to drive the transmission means (20) to move between a first predetermined position and a second predetermined position. 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 indication part (22) is disposed on a top surface of the transmission means (20) and a push button (10) has an opening window (12) provided in a predetermined position; when the indication part (22) is slid to the predetermined position, the indication part (22) is exposed out of the opening window (12). The embodiments of the present disclosure also provide a socket. With 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 (10) is pressed, so as to achieve the state indication of the switch. The number of parts is small and the structure is simple.

Claims (8)

1. A push-button , comprising: a push button; a rocker; a housing; a moving contact; a fixed contact; and a transmission device, the transmission device comprising; a transmission means comprising a driving part configured, in responding to a g action to the push-button, to drive, by the driving part, the rocker to pivot, wherein, the transmission means further comprises an indication part for providing an indication function of ting operation states of the push-button switch; an c means for driving the indication part to move so as to provide the indication function, the elastic means being disposed between the transmission means and the rocker, ing in a plane perpendicular to a pushing ion, and being configured to move in responding to a pivoting of the rocker, 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 ponds to an off state of the push-button switch; and wherein, the elastic means comprises an opening adapted to be fitted with a shaft protruding from the rocker, and is configured in such a manner that when the rocker pivots, the shaft of the rocker pushes an edge of the opening so as to pivot the elastic means; and wherein the indication part is disposed on a top surface of the transmission means and the push button has an opening window provided in a predetermined on; 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; and n the rocker is pivotably mounted to the housing and driven by the driving part to pivot, such that the moving contact is driven to pivot by the rocker, so as to contact or to be ted from the fixed contact.

2. The push-button switch according to claim 1, wherein the elastic means is pivotably mounted within the push-button switch.

3. The push-button switch according to claim 2, wherein, the elastic means is configured in the following : in the case that the transmission means is in the first predetermined on, when the push button is pushed to e the push-button switch, the elastic means pivots in a first direction within the plane perpendicular to the pushing direction and presses the transmission means so as to be deformed, and also, the transmission means is maintained in the first predetermined position and not moved; when the push button is ed, the transmission means is driven to move to the second predetermined position by a 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 is pushed to actuate the push-button switch, the elastic means pivots in a second direction opposite to the first direction and presses the transmission means so as to be ed, and also, the transmission means is maintained in the second predetermined position and not moved; when the push button is released, the transmission means is driven to move to the first predetermined position by the restoring force of the c means, so as to change the state indication of the push-button switch.

4. The push-button switch according to claim 1, wherein, the elastic means comprises two opened arms, namely first and second arms, the transmission means ses first and second pushing parts arranged correspondingly to the first and second arms; in the first predetermined position, the first arm abuts against the first pushing part; and in the second predetermined on, the second arm abuts against the second pushing part.

5. The push-button switch according to any one of claims 1-4, wherein, the transmission means is slidably mounted to the push button of the push-button switch.

6. The push-button switch according to claim 5, wherein, the push button is provided with a sliding rail, and the transmission means is slidably mounted to the sliding rail.

7. The push-button switch according to claim 6, wherein, the rocker is divided into a first portion and a second portion so as to divide the push-button switch into two parts, wherein, the first portion of the rocker, the moving t and the fixed contact form an installation panel adapted to be mounted to a fixed wall, the push , the transmission means, the elastic means and the second portion of the rocker form a cover separated from the installation panel portion, wherein the second portion of the rocker is d to a main body of the cover through a pivot shaft.

8. A socket, comprising a push-button switch according to any one of claims 1-7 for controlling power-on and power-off of the socket.
