2.3.1 Microswitches
- The microswitches must have a contact resistance lower than 0.1
Ω
and a
leakage current lower than 100 µA.
- When full load connected, the voltage drop between the key switch contacts
must be lower than 0.1 V.
-
The microswitches send a voltage signal to the microprocessor when a
