Thermal timing relay with bimetal actuated switch - has heat conductive support carrying heating element

摘要

The expansion element of the thermal time relay has a heating element for the switch (6) actuation on the expansion element movement. The switch is in thermal contact with a heat conductive support (1) which carries the heating element (2). Preferably the expansion element is connected in a threaded union (7) on the support. The support may be of strip shape whose one end (5) carries the switch, while the middle section mounts the heating element, which may be slidable in relation to the switch. certain parts of the support may be narrowed down.
