D1 Model Thermostats (DPST)

These are non-programmable, snap-acting, mechanical Double Pole, Single Throw (DPST) thermostats.  A DPST switch turns up to two independent circuits on or off.  All of these thermostats have options to include a NEMA 1 general-purpose enclosure and/or pilot light.

These controls are commonly used in tanks, ovens, cleaning baths, and many other applications and automatically turn off heating equipment when the set temperature is reached.
