The diagram shows output signal wave on the condition of  NC (Normal Close).
NO(Normal Open) is on the contrary.
On the condition that b=100ms .if switch dips to 20ms,then a=c=20ms;
if dips to 40ms,then a=c=40ms;
if 60ms,then a=c=60ms.              1. product name: GD106 Two-coin intelligent vending machine coin acceptor
