I have schematic for 140 as of 97.
S41 ECL switch has 170 Ohm resistor inside. S42 Windshield Washer switch has 110 Ohm resistor. The switches are in series and normaly open. So in normal condition IC would see 110+170=280Ohm.
If one of the switches gets closed resistor in this switch would be shorted out, and IC would see either 110 or 170 Ohm.
