A simplified mechanical and electromechanical interlock system connecting automatic transfer and bypass/isolation switches in a bypass/isolation automatic transfer switch is provided, whereby the risk of hazard resulting from the misconnection of power sources through automatic transfer and bypass/isolation switches is reduced by prevention of closure of the two switches into opposite or dead sources is prevented. Related retractable table structure is also provided for moving the automatic transfer switch from a frame in which the switches are housed.
