Above-mentioned sensing element is a working of plastics, and the surface is coated with chromium as reflector layer.Simultaneously, thus chromium also conducts electricity and can respond to.Above-mentioned sensing element also can be a metalwork.
Above-mentioned sensing element is to be contained on the wiring board at induction controller place by spring, and spring pushes up sensing element to panel.Above-mentioned panel inboard is provided with support, and support is with have can be for the pilot hole of sensing element guiding, and the nearly panel end of sensing element stretches in the pilot hole.
Above-mentioned support is provided with scattering sheet, and scattering sheet is arranged in the light transmission passage of sensing element.Scattering sheet can make distribution of light more even.Obviously, scattering sheet can be provided with separately, as long as be positioned at the nearly panel end of light transmission passage.
Also be provided with the status indicator lamp corresponding on the above-mentioned panel with sensing element.Status indicator lamp can illustrate the operating state of switching-on and switching-off state and each funtion part of electrical equipment.
The present invention is simple and reasonable, and no matter light and shade is operated all very convenient.Switch both combined together with panel, significantly showed Petting Area again, guided the hand touch action.Practical, and good looking appearance, create an aesthetic feeling.Can be applicable to various electrical equipment commonly used such as smoke exhaust ventilator, fan, washing machine, refrigerator, TV air-conditioning.
