A touch activation device effecting UV disinfection includes a body having a base substrate and a clear cover casing over the base substrate and combined there with to form a holding capacity, and a UV light-emitting diode disposed in the body and within the holding capacity. The clear cover casing has a touch area. The body, for example, is a push button, grip handle, cushion, switch or a knob. The user activates the touch activation device by touching the touch area of the clear cover casing. At the end of the user operation, the UV light-emitting diode emits UV light to disinfect the touch area to prevent germs from spreading to other people touching the device.本發明係有關於一種具紫外線抗菌功能之人體觸碰裝置，包括：一本體，有一基層以及一透明外殼覆蓋該基層而形成一容置空間，該透明外殼有一觸碰區，該本體例如按鍵、手把、坐墊、開關或旋鈕；一紫外光發光二極體，設置在該本體上且位在該容置空間中。使用者藉由觸碰該透明外殼之觸碰區來觸發觸碰裝置原始功能，並且當使用者操作完畢後，可藉由該紫外光發光二極體發出紫外光來對該透明外殼之觸碰區進行殺菌，避免細菌藉由不同使用者觸碰該觸碰區而四處傳播。
