Abstract: A circuit and method for controlling two or more electric relays, wherein at least one of the relays are rated to handle a higher voltage level while at least one of the relays are rated to handle a lower voltage level. A controller selectively activates the relays such that the higher voltage rated relay(s) open before but close after the lower voltage rated relay(s) within the system.
