- a magnetic field sensor 10 e.g. a giant magneto-resistor 10 (GMR 10)
- GMR 10 giant magneto-resistor 10
- the switching device is actuated 1
- the permanent magnet 9 moves with the contact carrier 5 and the anchor 4 with.
- the magnetic field change caused thereby the magnetic field sensor 10 is detected.
- the magnetic field sensor 10, here the GMR 10 creates a magnetic path s of permanent magnet 9 proportional resistance R, i.e. the resistance R is an image of the position of the permanent magnet 9 or the contact carrier 5 and the armature 4.
- the resistance R is an image of the position of the permanent magnet 9 or the contact carrier 5 and the armature 4.
- the sensor characteristic measured with the magnetic field sensor 10 2 shows the dependence of the resistance R on the magnetic path s specified
- a rectifier 11 At the input of the circuit with input terminals A1 and A2 for connecting a direct (DC) or alternating voltage (AC) is a rectifier 11, the output side of a series connection from the contactor coil 12 (corresponds to 3 in FIG 1), one Switching transistor 13 and a shunt 14 with voltage fed.
- To the contactor coil 12 is the one in a known manner Diode circuit forming freewheeling circuit connected in parallel.
- the current evaluation of the contactor coil takes place via the shunt 14 12, for which purpose the voltage applied to the shunt 14 is an analog-digital converter 15 and then a microprocessor 16 as intelligent control unit 16 is supplied.
- the microprocessor 16 via one at the output of the rectifier 11 ohmic divider the supply voltage applied there fed for evaluation.
- the microprocessor 16 a the resistance R of the magnetic field sensor 10 proportional voltage U supplied.

- the microprocessor 16 as an intelligent control unit 16 can thus by detecting the position and thus the Path-time profile of the contact carrier 5 during the switch-on process a speed-optimized switching on of the Switchgear drive can be achieved.
- the current speed of the drive is compared with one for the device optimal setpoint.
- the coil current adjusted accordingly and the desired ideal value of speed realized.
- the steps are according to the flow chart in FIG 4 made. Determined the intelligent control unit 16 after being switched on for the first time, that takes place with constant or unregulated current, the static rest position of the contact carrier 5.
- This reference value for the "ON" position is for all subsequent ones Switching operations stored, i.e. saved so that a elaborate adjustment and adjustment process can be omitted.
- at the subsequent switching operations according to the flow chart in FIG 5 can regulate the speed the contact carrier path based on a stored, to the device suitable characteristic curve for the path-time curve or the speed respectively. A speed reduction can shortly before the switching elements and the magnetic drive are closed be performed. This makes it clear Achieve increased mechanical and electrical life. It is also conceivable to change the speed to adapt and optimize to certain operating conditions.
