What is this for and how do I use it?
I found this a few years ago but I just took it apart to see what was in it and this is it. They are wired together to a two way plug. Would it be possible for someone explain what it is for and its purpose, and how I can use it for something?
BTW I forgot to ask can I test these with my multimeter or will it be to much for it? If I can what do i Set it on to test it. Thanks
