For some applications that have special demands for mounting space, the size of thermal switch would be extremely important. For example, battery pack, small motor and heating tube. They have no enough room to mount a thermal switch with bigger size. We now have two models with smallest size.
1. TS05, thickness 2mm only. It is now widely used for battery overheat protection and heating tube temperature control. This super thin thickness can make it insert into the batteries or heating tubes easily. The conductive leads can be wire or nickel strip.
2. TS01-NW series. It is 8mm diameter and 2.6mm thick, even smaller than a cell battery. It is used for PCB mounting. TS01 with lead wire is used in small coil, transformer, heating tube or motor. The max temperature can be 200C.
