Output:
A.singnal Inter-locking (Latch)----connect 2 and 3 ;
B.singnal Self-locking (Toggle) ---- connect 1 and 2 ;
C.singnal Non-locking (Momentary ) ---- All disconnect ;
· Toggle : Press->On; Press again->Off ;
· Latched : Press->On; Press other button->Off ;
· Momentary : Press and hold->On; Release->Off ;
