Arcade Microwitches. Why NC?

Pages: (1/2) > >>

Bones:

Question out of curiosity only....

Why bother have a (arcade) microswitch with a NC function?? What would be a practical example of choosing to wire to a switch to a NC connection?

For what we all do I can think of no reason!

 ???


versapak:

For starters...

These switches are not specifically arcade microswitches, and have many uses outside our beloved hobby.


Secondly...

There are actually switches out there that do NOT include the NC connection.


As far as our use for it...

You're right, there really isn't one.



Bones:

For my project I have actually been supplied the type that don't have the NC connection.

I suppose at the heart of my question I am left wondering why these are not more common for us folks if in fact there is no disadvantages.


crashwg:

Simple, because they're not Cherry!  :P

saint:

NC connections are used for dead-man switches on back doors. Rig a switch so that when the back door is on, the switch is closed. Remove the door, the switch goes open. If the switch goes open, kill power to the game. Stops people from poking around inside and getting hurt I suppose.

Usually those switches have a pull-out toggle of some kind that closes the switch while the door is open, but you have to know to pull it out.
