Terraria: Is the Inlet and Outlet Pumps only triggered when the Switch/Lever is between both?

I've been searching many guides about wiring, with my true intentions being figuring where the switch/lever has to be at allowing the inlet/outlet device to function (as one of my creations didn't seem to function). However, no guides have fully explained to me where exactly the switches need to be positioned at for the inlet/outlet device to function appropriately. Furthermore, additional information/links about the inlet/outlet device in particular would be deeply appreciated.

My issue could've been within the following:

  1. I had already created another circuit which functioned well and transferred the water from 1 designated place unto another. Within this Circuit, I used red wiring and placed the switch far right, away from the inlet/outlet device.
  2. However, I created my second circuit with blue wiring, clearly not touching nor trespassing the red wire at any parts. The switch is located far left and also away from both inlet/outlet device.

I understand it is hard to picture so I roughly drawn what I've done below.enter image description here

Here's an in-game screenshot as well

The switch can be anywhere on the wire. When a switch is activated, all devices connected to the same wire receive the signal.

As for your pumping problem: according to the wiki article on Pumps, and confirmed by my own testing,

When an Outlet Pump is submerged, the pumping stops.

You need to put your Outlet Pump above the water line. This pump setup will work:

Working pump

But this one will not:
