and are electrically connected to the posts 42 44 by staking the contacts shown in fig9 and 10 for use with the switch sections of this invention have double d type holes in their base portions for fitting over the upright connection posts of the switch sections each contact is placed over the posts and fit down onto the double d mating structure 186 on the connection the bottom of the contact is flush against the collar 188 the mating structure 186 once the contact is in place is mechanically compressed into the space remaining between the structure 186 and inwardly sloping sides of hole 190 the double d hole in the contacts together with the staking maintain sufficient pressure between the posts and the contacts to keep the contacts in good electrical connection with the posts the contacts 50 52 extend upward and angularly toward the center of the switch all of the fixed contacts f 50 and 52 are engageable with the rotor disks 54 the disks 54 have a square center hole 56 through which the shaft 12 extends each disk 54 is rotated by a handle 58 which is attached to both disks in rotating the disks 54 the handle 58 travels through a slot 60 in order to seal the interior elements of the switch section from the environment a tail 62 is attached to the handle 58 as the handle 58 is rotated to the 34 normal 34 position the tail 62 covers the slot 60 protecting the interior of the switch from the environment preventing dust and small particulate matter from getting inside the switch the disks 54 have matching substantially rectangular cut outs 64 these cut outs.
