This SPST (Single Pole Single Throw) temperature controller is built to handle significant electrical loads

a loose connection at these current levels is a recipe for a burnt block or worse

Snap-Acting Contacts: Dust-protected SPST contacts prevent arcing and ensure a clean break during temperature cycles

This specific model (C1B) incorporates 1/8-inch panel standoffs and a standard 3-second time delay on decreasing levels to filter out nuisance trips caused by turbulence or surging
