Description

Illuminated capacitive sensing switch

This creation is about inductive switches, especially an illuminated capacitive sensing switch.

Inductive switches are a variety of sensors that are used in many automated machines, semiconductor devices, machine tools, or various electronic products. The capacitive sensing switch works by generating a change in capacitance when an external object approaches and converting it into an electrical signal for use as a switch control.

In the conventional embodiment of the inductive switch, components such as a circuit board, a conductor, and a light-emitting element are disposed inside the crucible housing. Moreover, when an external object approaches or touches the inductive switching device, the generated electric charge is transmitted to the circuit board to generate a capacitance change as a basis for the switch control; in addition, the light emitting element also emits light when the capacitive sensing switch operates. In order to know that the capacitive sensing switch has been triggered to act.

However, the shell is mostly composed of an opaque material, and the surface thereof is provided with a conductor to conduct electric charge to limit the light-emitting area, so that the light emitted by the light-emitting element can only pass out from a local position on the surface of the housing. Therefore, it is difficult to identify and know the operating status.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The electric charge when the external object touches the housing can be transmitted to the control board through the guiding body, and the light is transmitted through the control board. The component emits light.

Compared with the prior art, the light-transmissive capacitive sensing switch of the present invention is made of a transparent plastic or glass material, and the charge generated by the contact is transmitted to the control panel through the arrangement of the guiding body, and The change in capacitance is calculated through the board to calculate the change in capacitance through the control board to cause the light emitting element to emit light.
