Thank you for that picture.
Do you know if the double switch version had the switches on top, and the single switch version had them underneath? In which case mine is the single. Is the test method the same, i.e. I should still get a click with throttle closed and then another with throttle wide open?

The '85 1.9 can have either 2 separate switches or "single" switch
(same as used on a 2.1) located under the throttle body.
Your engine has the "single" switch?
A click should be heard as throttle is opened just off idle, then
again a it's returned to stop position. If not, or it clicks too far
off idle position, "gap" adjustment may be wrong or (more unlikely)
switch has excessive internal wear or has failed. There could be other
causes.
The switch should also click when throttle turned to WOT (wide open throttle).
Corrosion, dirt at switch adjusting parts, excessive wear between
throttle shaft and body, can make it difficult to adjust and set this
switch.
A volt-ohm meter is mainly used to check for **consistent** switch on
off continuity as switch is actuated. Ensure meter probes connect
securely to switch to help eliminate false readings. On low Ohm
setting, you should see 0.00 Ohms or very close to that.
Attached pic: underside view of switch off my old 2.1 switch, assembly
rotated 90º out of the way. Normally, it sits over the adjuster cam
etc. As adjuster cam is turned (adjusted), that cam moves the switch
body which in turn affects where the metal switch arm is located
relative to the two lobes on plastic part, which is attached to the
throttle shaft.
