Nintendo DS Lite & DSI shoulder buttons

A couple of Nintendo DS's to look at, these are so popular, everybody seems to have several. Ive got a huge bag of bits from previous repairs. Re shelled ones, liquid damaged ones, damaged screens and digitizers.

Today was faulty shoulder buttons, one on a Lite one DSi. I hadt had a DSi appart before, it wasnt obvious from google or ebay but the switch is the same for both machines. I had a donar board for switches but thery are pretty cheap on ebay.

Here is the DS Lite with the switch about to go on.

Both the faulty switches clicked fine but were intermittent with their response, new switches fitted everything worked fine.
