摘要

Control arrangement for a relay or contactor has at least a coil (3), at least first and second contacts (4, 5) and a control element (11) for the coil. The control element has no direct contact with the coil and optimally comprises at least a magnetic-field sensitive element such as a reed switch as well as a temperature sensor.
