The light ring is arranged on the outer ring of the button cap and can transmit light, the button cap corresponds to the button, and after the button is pressed and started, the luminous body emits light with one color and penetrates out of the light ring to inform a user that the power supply is started at present. When the button cap is pressed again, the light emits another color of light, which passes through the aperture and informs the user that the power is now off. The pile body of the existing power supply is identified according to the light with different colors transmitted by the aperture, so that other buttons on the panel can be directly operated, repeated tests are not needed, misoperation is prevented, and the service life of the buttons is prolonged. The light ring surrounds the periphery of the button cap and corresponds to the light emitting body on the periphery of the button, the light energy of the light emitting body is directly emitted from the transparent light ring, the identification degree is good, and the operation of the button cap cannot be influenced.

Preferably, four light-emitting bodies are uniformly distributed around the button, two light-emitting bodies which are oppositely arranged form a group, and the two groups of light-emitting bodies are respectively turned on according to the on-off state of the button. Two by two are in one group, and two diodes on the same diameter are in one group, so that the whole aperture is uniform in light transmission. The two groups of luminous bodies respectively emit light with different colors, and the on-off of the button is identified at one time.

Preferably, the light emitting body is an LED, and the two groups of LEDs are different in color.

Preferably, the aperture is annular, a central hole of the aperture is in clearance fit with the button cap, and the annular width of the aperture is larger than that of the luminous body. Simple to operate, the light ring directly cup joints with the button cap on axial direction, and mutual location and installation are realized with the button cap to the light ring, and the annular width of light ring can let the light of luminous body see through obviously.

Preferably, the circuit board is provided with a mounting hole, and the screw penetrates through the mounting hole to fix the circuit board on the control panel. The button integral structure is arranged on a control panel, and the control panel is also provided with other medical appliance operation buttons, such as an endoscope display button, an endoscope light source button and the like. Fix the circuit board on control panel, also be exactly with whole button structure relatively fixed, simple structure, simple to operate.

Preferably, the button cap is provided with a connecting sheet, one end of the connecting sheet is connected with the button cap, the other end of the connecting sheet extends out of the circuit board, and the connecting sheet is fixed on the control panel.

Therefore, the utility model discloses a switch structure possesses following advantage: the structure is simple, the annular light ring is sleeved on the periphery of the button cap, and the projected part of the light ring on the circuit board is provided with two groups of light-emitting diodes with different colors, so that different colors can be displayed according to different shapes pressed by the button, and a user can clearly identify the power supply starting state of the equipment.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b):

as shown in fig. 1, 2, 3, 4 and 5, the power switch structure comprises a circuit board 1, through holes 10 are formed at four corners of the circuit board 1, and screws penetrate through the through holes 10 to fix the circuit board 1 on a control panel 9. A button 8 is installed in the center of the circuit board 1, four light emitting diodes 7 are evenly distributed on the periphery of the button 8, two opposite light emitting diodes 7 form a group, and the two groups of light emitting diodes 7 respectively display different colors. The button cap 2 is connected above the button 8, one end of the button cap 2 is connected with the button 8, and the other end of the button cap 2 extends out of the control panel 9. The button cap is the cylinder, is fixed with two connection pieces 5 on

button cap

2, and 5 one end of connection piece meet with button cap 2, and outside the other end extended to circuit board 1, the through-hole has been seted up on the connection piece 5, and the screw passes the through-hole and fixes button cap 2 on control panel 9. An annular diaphragm 3 is sleeved outside the button cap 2, and a light-emitting diode 7 is positioned in the projection area of the diaphragm 3 to the circuit board 1. So that the light emitted by the light emitting diode 7 can be transmitted out from the aperture 3, and the button cap 2 is made of opaque material. Two mounting lugs 4 are integrally formed on the diaphragm 3, and through holes are provided in the lugs 4, thereby fixing the diaphragm 3 to the circuit board 4.
