Conductive polymer circuit protection devices having improved electrodes

摘要: Circuit protection devices which contain PTC conductive polymer elements and are used in situations the device is mounted onto, or itself comprises, a rigid wall spaced apart from element through electrodes pass. The behavior of can be adversely affected if electrodes, prevented moving by wall, prevent expanding to extent necessary provide desired effect. invention includes use specially designed lessen danger that element, when it tripped, for effective operation.
