摘要
A movable contact assembly includes a base sheet made of insulating film, a contact provided under a bottom surface of the base sheet, and a conductive layer comprising silver paste on the base sheet. The silver paste contains 12 wt % to 15 wt % of resin binder and 35 wt % to 88 wt % of silver particles. The resin binder includes polyester resin having a glass-transition point ranging from 30° C. to 40° C. and an average molecular weight ranging from 30000 to 35000. The silver particles contain 70 wt % to 80 wt % of flake-shaped silver particles and 20 wt % to 30 wt % of dendritic silver particles. This conductive layer of the movable contact assembly can be baked at a low temperature, and does not have cracks and is not peeled off even when being bent. In addition, this conductive layer can easily cope with static electricity and has high reliability.
