Improved switch structure

An improved structure of a switch, especially a push-type switch with a light-emitting device, which can indicate the user's switch state.

In order to indicate the state of the switch in general electronic products, a light-emitting element is arranged on the circuit board of the electronic product and exposed to the housing of the electronic product. When the switch is triggered, the light-emitting element indicates the switch state, or Let the user know the position of the switch clearly, so that the user can operate it. This method will occupy the space on the circuit board and make the design of the housing difficult. Therefore, the relevant industry has installed the light-emitting element in the push switch , In order to solve the above problem, but because the push-type switch relies on the pusher to move up and down to trigger the signal, the light source emitted by the light-emitting element will be blocked by the pusher, and cannot be directly projected to the top of the pusher, or only the edge of the pusher appears The phenomenon of luminescence, but no light on the top, leads to poor indication of the push-type switch light source.

The pressing piece is made of light guide material. The triggering piece is arranged on the bottom surface of the pressing piece. The bottom surface is formed with a light-incident surface at the periphery of the trigger member, and the surface of the pressing member is formed with a light-emitting surface, and the trigger member is located in the hollow part, so that the light-incident surface faces the light-emitting device, so that the light source emitted by the light-emitting device is from the light-incident surface After entering, it is projected from the light-emitting surface to the outside world.

In the improved structure of the aforementioned switch, the light-emitting device has a circuit substrate and a light-emitting element arranged on the circuit substrate, the hollow part is arranged on the circuit substrate, and the light-emitting element is located on the periphery of the hollow part and faces the light-incident surface of the pressing device.

In the aforementioned improved structure of the switch, the light-emitting device is provided with a lens above the light-emitting element.

In the above-mentioned improved switch structure, the base of the body set is provided with a first accommodating space, the base is recessed with a second accommodating space on the bottom surface of the first accommodating space, and the trigger spring is positioned in the second accommodating space Inside, the light emitting device is positioned in the first accommodating space.

In the aforementioned improved structure of the switch, the base of the body set is covered with an upper cover, the upper cover is provided with a through hole, the pressing piece of the pressing device is exposed outside the body set through the through hole, and the bottom periphery of the pressing piece is horizontally convexly provided The stop part is against the bottom surface of the upper cover.
