On the Assessment of Capacitive Touch Switch in Household Electrical Appliance
As for most capacitive touch switch module implemented in nowadays electronic and electrical appliances,human body is integrated as part of the detection circuit.Therefore,the relevant part of the detection circuit shall satisfy the requirement of protective impedance.Negligence of such requirement might on one hand misinterpret the dielectric testing and ball-pressure testing,and on the other hand overlook the requirement pertinent to simulation fault in electronic circuit.Both the testing houses and manufacturers should be altered to the situation that the verification of the reliability of electronic switch in the electrical appliance standards is far from perfect.
