Control arrangement and method for electronic device

A control arrangement for a source-transfer switching system of the type that includes first and second solid-state switches having respective first and second control inputs, input source connections and output connections, the output connections being connected to a common load circuit connection, the control arrangement comprising:

• transfer control means for controlling the first and second solid-state switches via the first and second control inputs so as to selectively supply the common load circuit connection via either the first or second solid-state switch, said transfer control means further comprising first control means for providing a switch control signal for each of said first and second solid-state switches to selectively change the conductive state of either the first or second solid-state switch and switch control means responsive to said switch control signals for controlling the conductive state of the first and second solid-state switches via the first and second control inputs and maintaining the first and second solid-state switches in the conductive state via continuously providing a conductive state signal until the receipt of said switch control signal to render the first or second solid-state switch nonconductive whereby the conductive state of the first or second solid-state switch is maintained in the conductive state independent of the input source connections, said control means further providing predetermined on and off switch control signals for each of said first and second solid-state switches.
