Thermally controlled electrical switching device having a snap-action switch |
摘要 |
The invention relates to a thermally controlled electrical switching device including a temperature control (1) having a snap-action switch (2) including a fixed contact (4) and a movable contact (3) connected to a metal snap-action switching spring (9), and having a bimetallic element (5) which influences the movement of the movable contact. In order to minimize the heat produced in the mechanically loaded parts (17, 18) of the snap-action switching spring (9) the switching devices limits the current through these mechanically loaded parts. These devices may include an electrically well conductive layer (30) provided on the non-mechanically loaded parts of the snap-action switching spring or a layer (31) having a high electrical resistance deposited on the mechanically loaded parts (17, 18).
