Adjustable temperature
High switching capacity
Small hysteresis
Terminals easily accessible
Clip fixing
Change-over contact

The mechanical thermostat is used for controlling heating and cooling equipment, filter fans or signal devices. The thermostat registers the surrounding air and can switch both inductive and resistive loads via snap-action contact.

Approvals -
*Connecting terminal "N" (RF heating resistor) causes the thermal feedback to work and so reduces the switch temperature difference to approx. 0.5K.
