Well it works! It’s actually a perfect replacement for the original equipment Hi Limit Temperature Switch. The install would have been easy but this switch on my particular model, is buried in the back of the furnace cage. However, this is not a representation of this switch. The switch is perfect fit and I’ve had no issues so far. I recommend it. I would taken a picture of it installed, but my iPhone couldn’t zoom in that far back in the cage and it was dark under the cabinet where my furnace is located.

Note that this is a normally closed switch and opens when it hits its set point to indicate an overheat condition.The description says 190 degrees, but the switch case says 95 degrees Celsius = 203 degrees Fahrenheit... so if your use case is senstive to that difference you should be aware and/or test to make sure this will do what you need.
