Multi-Function Switch Actuator, Sequencing Mechanism

      Described is a arrangement to transfer motion from a
remote actuator to a switch while ensuring proper sequencing between
power on/off and system loading.

      The Switch Link 2 is a multi-function part which transfers a
vertical motion from Actuator 5 to a horizontal motion required to
turn the Power Supply Switch 1 on or off. It also has an interlock
surface which interacts with Stop Arm 7 to ensure that the Load Lever
8 and actuator 5 can only be activated in the proper sequence.

      Motion transfer is accomplished when the front of actuator 5,
which is held in place and rotates about Pin 4, is raised or lowered.
The stud on the rear of the actuator 5, which is inserted in the slot
in Link 2, moved up or down and rotates the Link 2 about Pin 6.
This rotation causes the "V"-shaped opening of Link 2, which brackets
the Power Supply Switch 1, to move left or right, thereby turning the
Power Supply Switch 1 on or off.

      Sequencing is accomplished when the Link 2 rotates and causes
the Stop Surface 3 on the Link 2 to raise and interfere with the Stop
Arm 7 which is connected to the Load Lever 8.  With the Load Lever 8
in the Far Right Position and the Stop Surface 3 in the raised
position the Load Lever 8 cannot be moved to the left because the
Stop Arm 7 would strike the Stop Surface 3.  With the Stop Surface 3
down, the Load Lever 8 is free to move to the left and the Stop
Arm 7 passes ov...
