I want to order this thermostat: http://dblrsupply.pinnaclecart.com/incubator-repair-parts/incubator-thermostat-switch/ It is for my homemade incubator. I am just making sure that this is the right thermostat? It says "Wafer Thermostat Switch" but I can not find anything else on the website. Is this the complete thermostat? Thanks in advance.
