Abstract
An appliance provided with an electric motor and a circuit for driving the electric motor. The drive circuit includes a first pulse switch (S1) for generating a first pulse and a first switching device (.mu.C, T) having a holding capability and which performs a first switching function in response to the first pulse. A second pulse switch (S2) generates a second pulse. A second switching device (Th, R) having a holding capability performs a second switching function in response to the second pulse. A main switching device switches the electric motor. The first switching function in combination with the second switching fucntion are adapted to control the main switching device. Optionally, the circuit may include a control device (Tr) for controlling the electric motor and a third pulse switch (S3) for resetting the first switching function.
