== Plusieurs senseurs, une branche/ligne, une broche ==

You can use nearly unlimited sensor switches if you place multiple switches in a branch. The branch can sense one switch out of all that may have changed state in a branch. In this manner you can only tell if any one of the multiple sensors in the branch has tripped. You can do this using normally open sensors in parallel or normally closed sensors in series. You can use both types of sensors putting the closed switches in line and the open switches in parallel. The resistor pulls the circuit high if the loop is opened otherwise the loop is grounded.

Avec ce procédé, il est uniquement possible de savoir d'un senseur à changé d'état mais pas quel senseur de la branche/ligne. Pour pouvez réaliser un tel montage à l'aide de senseurs/commutateurs normalement ouvert montés en parallèle ou des commutateurs normalement fermés montés en série. You can use both types of sensors putting the closed switches in line and the open switches in parallel. The resistor pulls the circuit high if the loop is opened otherwise the loop is grounded.
