The invention relates to a protection switch (12) having a mechanical switch (26) which is introduced into a main current path (18) and which has a fixed contact and a movable contact (34) which is connected to a contact bridge (32) which is mounted so as to be movable relative to the fixed contact. The protection switch comprises a driver (38) which is operatively connected to the contact bridge (32) and which has a first drive unit (39) and a second drive unit (56). The first drive unit (39) is energized by means of a control circuit (42) and the second drive unit (56) is connected in parallel to a resistive element (51) introduced into the main current path (18). The invention also relates to a vehicle (2).
本发明涉及一种保护开关(12),其具有被引入到主电流路径(18)内的机械开关(26),机械开关具有固定接触部和接驳在以能相对固定接触部运动的方式被支承的接触桥(32)上的运动接触部(34)。保护开关包括驱动器(38),驱动器与接触桥(32)作用连接,并且驱动器具有第一驱动单元(39)和第二驱动单元(56)。第一驱动单元(39)借助控制回路(42)通电,并且第二驱动单元(56)与被引入到主电流路径(18)内的电阻元件(51)并联。本发明还涉及一种交通工具(2)。
