TEMPERATURE-DEPENDENT SWITCH AND METHOD FOR MANUFACTURING A TEMPERATURE-DEPENDENT SWITCH

摘要

Temperature-dependent switch (10) with a first electrode (22), a second electrode (24), a temperature-dependent switching mechanism (14) and a housing (12) accommodating the switching mechanism (14), the first electrode (22) having an inside of the housing (12) arranged stationary contact (28) is connected and the switching mechanism (14) has a component (42) which is movable relative to the housing (12) and on which a movable contact part (40) is arranged, and wherein the switching mechanism ( 14) is set up, depending on its temperature, between a closed state of the switch (10) in which the movable contact part (40) interacts with the stationary contact (28) and an electrically conductive connection between the first and the second electrode ( 22, 24), and an open state of the switch (10) in which the movable contact part (40) is lifted from the stationary contact (28) and an electrically conductive connection between the first and second electrodes (22, 24) are opened, a first connection part (31, 31a) being attached to the first electrode (22) by a first welded connection produced by means of ultrasonic welding and / or a second connection part (33) is attached to the second electrode (24) by a second weld connection produced by means of ultrasonic welding. and / or the stationary contact (28) is fastened to a part (26, 96) of the first electrode (22) arranged in the interior of the housing (12) by a third weld connection produced by means of ultrasonic welding and / or the movable contact part (40) by a fourth weld connection produced by means of ultrasonic welding is fastened to the movable component (42).
