Electrical Solution
Full View
This image shows the entire mechanical setup for the button with the reset lever visible.
Side View
This image shows the housing for the button itself with the lock mechanims located to the right of the copper housing.
Before Reset
The screw attached to the copper housing is used to reset the button, which is currently unlocked, through the use of the hinge located to the right of the screw itself.
After Reset
To reset, the lever is used to move the hinge so that the cut out on the hinge pushes the screw down into the locked position.
