I don't think it's entirely unreasonable. It's cheap. It probably works well, if all you care about is a digital signal and if your environment is reasonably noise free. And quite possibly, this is from an older device when cheap and small current sensors weren't even available yet.
Today, you can get neat little current sensors like this: https://www.allegromicro.com/en/Products/Sense/Current-Sensor-ICs/Zero-To-Fifty-Amp-Integrated-Conductor-Sensor-ICs The downside is that it probably costs several dollars, and that it needs a supply voltage.
Or you can bulky non-invasive current transformers like this: https://www.amazon.com/Dwyer-Miniature-Current-MCS-111050-Continuous/dp/B00I9IFJOM Works great, but costs a fortune and is rather bulky.
But the little "ghetto current switch" is honestly not that bad by comparison. If it does the job, then why bother replacing it with something else? Apparently, this is still a common application in household appliances: https://www.reed-sensor.com/applications/white-goods/food-processors/
It comes pretty good. I do really like side snips - https://www.amazon.com/Hakko-CHP-170-Micro-Cutter/dp/B076M3ZHBV/ref=sr_1_3?s=power-hand-tools&amp;ie=UTF8&amp;qid=1519155543&amp;sr=1-3&amp;keywords=side+cutters
And if you are shopping I would swap the part fan and thermistor:
https://www.amazon.com/Thermistor-Reprap-3D-Printer-Extruder/dp/B01DCFJBCC/ref=sr_1_2?s=industrial&amp;ie=UTF8&amp;qid=1519155599&amp;sr=1-2&amp;keywords=m3+thermistor&amp;dpID=51tiPDgI0ZL&amp;preST=_SX342_QL70_&amp;dpSrc=srch
https://www.amazon.com/Uxcell-a14112600ux0241-Brushless-Sleeve-Bearing-Cooling/dp/B016XMK6SE/ref=sr_1_4?s=industrial&amp;ie=UTF8&amp;qid=1519155631&amp;sr=1-4&amp;keywords=24v+blower+fan&amp;dpID=31iOokGKhLL&amp;preST=_SX342_QL70_&amp;dpSrc=srch
The thermistor I would swap right away. Lastly don't buy monoprice filament. Look at AIO Robotics, Esun, Hatchbox, AMZ3D, etc.

I've been using this one on a Petsfang for 4 months now:

Works great, part quality is awesome. I mostly print with Sunlu PLA+ or Hatchbox PETG.
Current Sensing Relay, 0.15A, Self Powered
https://www.amazon.com/dp/B008FM2WEC/
much better for you im assuming you have no more than 1A@12V in fans total they are nominally 015 to 0.26A each usually* so 4 or 3 fans , run the DC 12+ from the supply to terminal block and then from the other to all the fans.
