Section 2
Switch Control
The four-pin electrical interface is used to control and
monitor switch position. The electrical connector is
Molex P/N 22-23-2041, and mates with Molex P/N 22-
01-3047 or equivalent.
Pin 4 is the position sensor output. The output
alternates between normal open contact and normal
close contact (low or high signal) depending on the
switch position. The position sensor is powered with
+5 VDC on pin 3. Pins 1, 2 and 3 are used for control
and power supply. Pin behavior depends upon the
electrical configuration of the user's switch. The
electrical configuration is described in the following
section, and summarized in Table 2.1, and Table 2.2.
