## Abstract

A switch structure having a display and playback device is proposed. The switch structure comprises an upper housing and a lower housing jointly enclosing therein the display and playback device that is connected to a circuit board. A resilient member is provided for supporting and positioning internal components of the switch structure. A display-and-playback-device housing has support rods provided at two sides thereof to prevent the switch structure from slanting when pressed. When a conductor and a terminal settled in the lower housing connect with or disconnect from each other, functions of opening and closing a circuit and enabling signal input are enabled. The display and playback device plays back and displays dynamic and still images to indicate functions and state of use of an equipment and enable personalized panels, thereby improving work efficiency and accuracy of operation.

## Claims

### Claim 1

A switch structure having a display and playback device, the switch structure comprising an upper housing and a lower housing jointly enclosing therein the display and playback device, two support rods, a resilient member, a circuit board, a conductor, a terminal, a transparent member, a display-and-playback-device housing and a resilient-member socket; the transparent member located at the upper housing for allowing dynamic and still images played back and displayed by the display and playback device to be exhibited therethrough; the display and playback device settled in the display-and-playback-device housing for playing back and displaying the dynamic and still images; the resilient member settled in the resilient-member socket; the conductor settled in the lower housing; the terminal settled in the lower housing;
the display-and-playback-device housing having a lower portion provided with rod retainers and an arm; the two support rods retained by the rod retainers at the lower portion of the display-and-playback-device housing; the circuit board settled inside the upper and lower housings and connected to the display and playback device; and
the resilient-member socket receiving the resilient member therein; the switch structure being characterized in that: when a biased downward external force is applied to the upper housing, the resilient member is compressed, and the support rods rotate against the rod retainers to counteract a horizontal component of the external force so as to ensure smooth vertical movement of the switch structure.

### Claim 2 (depends on 1)

The switch structure of claim 1, wherein the conductor and the terminal are independent components.

### Claim 3 (depends on 1)

The switch structure of claim 1, wherein the conductor and the terminal are capable of switching functions of the display and playback device.
