Abstract
A switching device for a coil is specified, having an input connection, for connection to a coil electronics system and/or to a resonant circuit capacitor, an output connection, for connection to an end of the coil and/or to a resonant circuit capacitor, and a disconnecting device, wherein the disconnecting device is able to be switched between an on-state and an off-state, the disconnecting device connects the input connection and the output connection to an on-impedance in the on-state, and the disconnecting device connects the input connection and the output connection to an off-impedance in the off-state, the off-impedance has an increased value compared to the on-impedance, the off-impedance permits a flow of current between the input connection and the output connection, and the off-impedance is formed so as to damp at least one external signal of a definable frequency, the external signal being coupled into the coil.
