Momentary Contact Switch Card
The beauty of the card is that it makes the switch wiring simple if you are building
a push button controlled, multi track video kiosk or display.
As an exhibit builder your focus is on the message not wiring switches.
This card uses convenient screw terminals to connect any kind of SPST contact
switches in a simple, logical manner so you can spend your time selecting
beautiful switches, engraving buttons or panels and integrating them into the
display. Should a switch ever fail, you can change two wires by loosening two
screws.
The card also has a DB9 connector. You can use nine pin male to male cables
and connectors.
