High temperature superconductors are particularly suitable as high power switches, due to its fast transition into normal conductivity. The switching operation can be triggered e.g. by a thermal pulse. In this dissertation a new kind of trigger, based on a low power radio frequency pulse, was investigated. Beside the research on different important parameters for the switching operation, a theory for the switching mechanism was developed. A simulation proved this theory. The development of a new switching element permitted the enhancement of the frequency range for the trigger pulse from a few 10 MHz down to a few 100 kHz. Up to now the shortest switching time achieved by a radio frequency trigger is 39 µs.
