Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes.

Temperature instruments use contact or noncontact methods to measure temperature.

Lighting controls include monitors, communication systems, and other devices for controlling facility lighting systems

HVAC controllers are used to monitor and control heating, ventilation and air conditioning (HVAC) systems in buildings.

Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level

Environmental controllers control environmental factors such as temperature, humidity, and air pressure.

Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire.
