DieCubsDie Posted August 14, 2013 Share Posted August 14, 2013 I'm about to start building my cabinet and I've just recently ordered my microswitches. I understand the concept of NO/NC, but I don't understand why you would ever need to use the NC contact on a microswitch. Are there any circumstances where you would use this?

Lupin_IV Posted August 14, 2013 Share Posted August 14, 2013 Say you wanted to place a light inside your cabinet that will turn on when the coin door is opened, you could position a normally closed switch so that it is pressed (opening the circuit) when the door closes.

fuzzykeuh Posted August 14, 2013 Share Posted August 14, 2013 I think its just a mather of common use of those microswitches, arcade buttons is just one of many uses. In the industry, NC contacts are often used in circuits that need a wire-break safety (example: Emergency stops). If a wire breaks, circuit will act like the contact is open "logic 0" (and not the normal NC "logic 1" status) Link to comment Share on other sites More sharing options...
DieCubsDie Posted August 15, 2013 Author Share Posted August 15, 2013 I guess I'm just wondering if there is any reason to have a NC button on your arcade panel. Basically just wondering if anyone has found any use for it. Link to comment Share on other sites More sharing options...

Polemicist Posted August 15, 2013 Share Posted August 15, 2013 I've found that Arcade micros get used in a lot of strange places because of their reliability so having the two options never surprised me. Link to comment Share on other sites More sharing options...
