ABSTRACT:
A double throw switch linkage for coupling two switch apparatuses together in an enclosure. Each switch apparatus is coupled to the switch mechanism having a switch mechanism lever arm. When the lever arm is moved it translates a force to the actuator plate which closes one switch mechanism and maintains the other switch mechanism in an open position.
