Pic 2-8 recommended wiring for general input pins
For these pins the resistor of the switch should be below 100ohm.

Wether to introduce R1 depends on the voltage. The goal here is to ensure that the input
current is between 10mA and 15mA. If the voltage is over 12V, we recommend a current-limiting
resistor. Assume that the current you choose is 12mA, then the resistor is calculated as follow:
