The method and arrangement are for controlling a contactor, which comprises a coil (1) connectable to a voltage source and at least one contact activated when a current of sufficiently high value flows through the coil. The control arrangement incorporates components (2,4) which control the voltage fed to the coil in such a way that the voltage pulses are fed at a higher average value during the switching on process than during running. |
