Depending on the ladder diagram, two solutions are possible:
Ladder diagram 1: Light off when idle
Ladder diagram 2: Light on when idle
I1-------------[Q1
i1-------------[Q1
I1 corresponds to the true image of BP1,
i1 corresponds to the reverse image of BP1,
pressing BP1 activates input I1, so that the Q1 pressing BP1 activates input I1 and
therefore contact i1 is disabled, output Q1 is
output is activated and the lamp L1 turns on.
