Nope.
The lower contact doesnt push the battery. (Otherwise the battery would rattle around when the button is released)
Once the battery and atty are installed the battery doesn't move.
The throw of the switch is stopped by the end of the button. The soft copper or brass contact only moves to touch the cell.
It only closes the gap, it doesnt push the cell and more force wont make it move farther.
At least thats how it works on the 130+ mechs I own.

Please show me an example if you know of one and Ill be happy to show you how it works.
