Realized are a switch on/off control method and a switch circuit that can reduce a processing load when controlling on/off of a switch whose various operations are controlled based on control data. All commands in a command table 131 included in a RAM 13 are DMA-transferred to an SPI controller 17, and the DMA-transferred commands are transmitted to an IPD 18 via SPI communication, so as to perform on/off control. DIAG commands irrelevant to the on/off control of the IPD 18 are written in advance in the entire region of the command table 131, transfer source addresses from which the commands are DMA-transferred to the IPD 18 at phases at which the IPD 18 is to be controlled to be turned on and off are calculated, and an ON command and an OFF command for controlling the IPD 18 to be turned on and off are written over the diagnosis commands that were written in advance at the calculated transfer source addresses.
