PROBLEM TO BE SOLVED: To provide a non-contact power supply device for control wherein drive control on a load 13 connected with a secondary unit 12 can be quickly varied without fail by operating switches provided on the operating portion 18 of a primary unit 9. SOLUTION: The non-contact power supply device for control is so constituted that it comprises: a first controller 19 that outputs binary data corresponding to the details of operation of the various switches 24a to 24d on the operating portion 18; a change-over circuit 20 that converts the binary data into a high-frequency signal composed of two different types of frequencies; a first coupling transformer 15 that transmits the high-frequency signal to the secondary side; a noise filter circuit 44 that converts the high-frequency signal, transmitted to the secondary side, into a pulse signal; a data demodulation circuit 56 that demodulates the pulse signal to the binary data; and a second controller 46 that controls a load 13 based on the demodulated binary data.
