One of the very reasons why I always felt intimidated by electronics are the overabundant acronyms with seemingly no explanation to what they mean or how to find out.

I've found that Interface Bus seems to have a fairly intuitive (yet fairly small...?) list, and I can appreciate the search function of epanorama. Does anyone have a tried and true resource for acronyms? Simply looking to google for an explanation can be mind boggling because there are so many possible answers.

For example I am trying my damnedest to figure out what PDT stands for in relation to a simple toggle. Its prefaced with a number usually (1,2,3, or 4 that I have seen..nothing higher than that.) Click here for an example, this is an ebay auction for a toggle. Does it mean 'programmable data terminal'? This seems doubtful, but...possible? What do you think?:confused:
