are there any mechanisms out there to help prevent overheating during incubation??? like an emergenc

Both switches should be the regular, normally closed type , wired in series . That way the backup thermostat can break the circuit if the primary sticks in the on position preventing overheating. At least that is the way they are usually wired.

you are right, i had a brain fart- im prone to those every now and then.

the way they work is when the wafer expands (from heat) they push on the switch and open the circuit, turning the heating element off.

ive been playing so much with turner ideas i wasn't thinking right. i apologize for my mistake.

Dual wafer thermostats is pretty hard to beat, old school, and reliable.

i agree completely, ive had digital, and dual wafer thermostats. the digital never seemed to last long, i do hear brisnea makes a good one, but ive never owned one of theirs.

right now i use Sportsman cabinets with dual wafer thermostats. my chicks are healthier, dry out better, and look better out of these cabinets. my hatches almost always hit day 18-19 on bantams and 21 with a few late bloomers on standards. i probably don't touch the temp adjustments on them over 3-4 times a year, and thats usually after i bump them when cleaning the incubator. i have had one switch fail on one incubator. and there is a way to rig around that, if you dont have the replacement parts.

bachbach1 you can post a link to them, but i think all sales through the site has to be done in the buy sales and trade area. if you offer them in a thread ask anyone interested to PM you. in fact im PMing you right now for specs and a link.
