Great value
I bought this sail switch to keep as a spare in case ours fails again.

Fixed the problem
I bought 3 different sail switches from Amazon that didn’t fit my application. This one worked and have backups just in case it ever fails again. Easy fix and saved money doing it myself.

works just as needed with Mod...
I installed an electronic filter in the furnace. It was plugged in continuously. Installed this inline so the filter was off when the furnace was off and on when the furnace was. The blade wasn't large enough to active the switch. I cut and folded a 1" x 1" piece of screen and glued it on the switch blade. Works perfect. You can hear it mate when the furnace comes on. Thanks so very much, JK
