Switch Circuit
The 24V supplied from the external power source is supplied to the required locations in this
circuit. The supply power source and application are described below. The 5V system has the
same type of switch, which is also turned on and off to configure it at the same time. The circuit
is configured with a MOSFET semiconductor switch. Q44 is a 2-element MOSFET that turns the
VCC_PRW and VCC_SEN on and off.
