Abstract: 열감응스위치(1)는 도전단자를 기밀로 절연고정된 금속제의 뚜껑판과, 이 뚜껑판의 외부원주근방에 개방구단말을 용접시키는 저면이있는 원통형의 금속용기(3)에의해 밀폐용기를 구성하고있다. 
     이 밀폐용기의 내부에는 얕은 접시형상으로 성형된 원판상의 열응동판(9)이 수납되고, 열응동판(9)의 동작에의해 고정접점부와 가동접점을 개폐시키는 접점기구를 갖고있다. 
     열감응스위치(1)의 금속용기(3)는 원통부의 두께를 t, 길이를 L, 직경을 D로한때 t/L=1/60∼1/20로, L 0.5D의 관계가 되도록 설정하므로서 용기저면(3B)으로부터 열응동판에의 열전도와 뚜껑판방향으로의 원통부를 통한 열전도가 각각 규정된다. 
     이때문에 열응동판(9)을 가열해야할 열의 뚜껑판방향으로의 전달속도를 억제하므로서 용기저면(3B)의 온도상승이 빨라지고 스위치로서의 열응답속도를 빨리할수가있다.
