A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip , often encased in a tubular glass bulb to protect it from dust or short circuit .
Typical LED package including thermal management design Thermal animation of a high powered A19 sized LED light bulb, created using high resolution computational fluid dynamics (CFD) analysis software, showing temperature contoured LED heat sink and flow trajectories Thermal animation of a high power density industrial PAR 64 LED downlight heat sink design, created using high resolution CFD ...
The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. The magnetic lock relies upon some of the basic concepts of electromagnetism.

Within the heating assembly are the circular halogen lamp, a fan, [3] and the controls for the oven which frequently include an automatic shut-off timer and a temperature control interface. [2] [4] On a basic model, the heating assembly has a handle to allow users to safely lift the lid off the unit. More elaborate models have a hinged lid ...
The lighter was put in a toaster oven to simulate the maximum temperature that the interior of a car can reach, around 180 °F (82 °C). There was no reaction for several hours, and the lighter finally exploded when the MythBusters ramped the temperature up to over 350 °F (177 °C), well above any temperature that can be expected in the ...
In 1998, Whirlpool's KitchenAid line patented a "Sabbath mode", and since then many manufacturers have followed by offering similar options. These modes typically turn off the electronic displays, disable oven and refrigerator lights that turn on automatically, and use delay timers that allow for permitted temperature controls. [34]
