Weird circuit in a datasheet
« on: September 19, 2020, 12:06:33 am »
Hi,

I'm looking at a potentiometer with a built-in switch. Here's the datasheet: https://www.ttelectronics.com/TTElectronics/media/ProductFiles/Potentiometers/Datasheets/P170.pdf

There's a drawing in the datasheet on page 7 that I don't understand. It's the pot's circuit diagram. What the heck does it mean?

Thank you,
   Bob

If you are referring to the horizontal line, it shows that the switch and the pot sections are operated by the same common shaft.

Thank you. That was one of the things confusing me.

The OFF and ON lines also bother me. I mean, I'm reasonably confident that the two "SW" terminals (shown in the drawing of the pot) get connected, but the circuit diagram sure isn't drawn the way I'd expect a switch to be drawn.

True, not the best representation.
