In Reply to: Connecting up a Hagstrom LP24? posted by JP4 on July 21, 1999 at 17:55:48:
: I hate to ask a potentially simple question, but I've poured through every website that I can find and I haven't found the answer. I'm going to be hooking up Happs microswitched buttons and joysticks to a Hagstrom LP24, and I'm going to set the LP24 to a 22x2 matrix. If I use the example of the 22x2 matrix that's on the "Interfaces" part of this page (where up1 is "A1" and down1 is "B1", which of the pins on the microswitches gets connected to which of the inputs on the LP24? I'm just afraid of toasting the LP24, so I want to be sure. Thanks in advance!!

There are 3 pins on the microswitch. N.O. (normally open) N.C. (Normally closed) and a common. The 2 pins you want are the common and the N.O. It wont matter which wire you hook to which since all you are doing when you depress the button is completing the circuit between the 2 connectors.
