#186449 - not Button it is a limit switch
Responding to: Erik Malund's previous message
The Limit switch LED Indicator has a LED Series With 10K Resister and Diode.

When All 6 limit Switch Closed The Constant Current Circuit Limit the Current 5mA Each Circuit = 6x5mA = 30mA.
When a Limit Switch open the Constant Current Circuit come series with switch LED Indicator which consumes only 2mA.
the Micro monitor the current consumed by the Limit switch Circuit.
