摘　　要：对于电子电器产品常用的电容式触摸开关模块,人体是检测电路的一部分,因此,检测电路必须满足保护阻抗的要求;忽视了电容式触摸开关模块的这一特点,在认证检测过程中,一方面,很可能在电气强度试验、球压测试中出现误判,另一方面,很可能在电子电路模拟故障的相关测试中出现漏判。目前IEC体系的家电产品标准对于电子开关的操作可靠性的关注程度不尽理想,认证检测机构及相关企业应对此有一定的警觉。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.
