Abstract of the Disclosure.
According to the invention, a switching device based
on an active switching element is built around an operatio-
nal amplifier featuring two switching components connected
in series in the negative feedback circuit. The positive
feedback circuit of the operational amplifier comprises a
voltage divider having two resistors and an operational am-
plifier whose non-inverting input is coupled to the centre
tap of the power sources of both operational amplifiers and
the output busbar. The inverting input of the operational am-
plifier of the voltage divider is connected to the non-inven-
ting input of the operational amplifier of the active switch-
ing element whose output is coupled to the output of the ope-
rational amplifier of the voltage divider via series-connec-
ted resistors. One of the resistors is connected between the
output and the non-inverting input of the operational ampli-
fier of the active switching element.
