How is this battery spring plate attached to the plastic casing? Answered

Hi,

The picture is showing the battery compartment of my kitchen scale. I would like to use this principle in my design and wonder if anyone can tell me how the metal springs are attached to the plastic?

Double molded, glued, clip-in...?

My design does not have a PCB, which I suppose this scale has. 

I am not an electrical engineer so sorry for a confusing question.
Thanks!

The battery plates slot into the grooves in the plastic. They will either be retained in place by a slight overhang or clip on the plastic, or there may be an adhesive, it's hard to say for sure from the photo.

The battery plate at the top of the photo is a single piece to link the positive (+) terminal of one battery to the negative (-) of the other, this means the two 1.5v batteries are wired in series and will thereby supply 3v. The two battery plates at the bottom of the photo will connect to the PCB internally.

Some Springs can be mounted on perforated board to take AAA, AA and 9V batteries...
