Latest Patents

One of Per Andersen's latest patents is the "Snap Switch." This invention relates to a toggle type snap switch featuring an operating arm and a switching arm, with a toggle spring hingedly connected between these arms. In one embodiment, the toggle spring is designed as a plate with a window at one end. The switching arm consists of separate, relatively movable snap arm and switching arm sections, with a hinge connection between the toggle spring and the switching arm section. The window in the toggle spring has upper and lower edges that alternately engage with the free end of the snap arm section for opposite snap positions of the operating arm. Additionally, the window may include laterally extended slot sections that form part of the hinge connection.

Another significant patent by Per Andersen is the "Defrosting Apparatus for a Refrigerator." This invention pertains to a refrigeration assembly, particularly focusing on defrosting mechanisms. The assembly includes a bellows-operated thermostatic motor switch that responds to evaporator temperatures to operate the compressor motor. After a predetermined number of operating cycles, the defrost apparatus is activated. A linkage between the bellows and the motor switch features a main spring that opposes the bellows and a differential spring that assists it. The differential spring becomes inoperative during the defrost setting, allowing the main spring to actuate the motor switch at a higher evaporator temperature.
