Aladdin Industries filed key "Aladdin Lamps" patents in 1954 and 1956, [1] [2] and commercial models were available by 1955. [3] However, due to low electrical efficiency and high price of the vacuum tube-based product, the concept was not popularized until later versions of the touch mechanism used integrated circuits and transistors to improve efficiency and reduce cost in the mid 1980s.
A touch switch is a type of switch that only has to be touched by an object to operate. It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.
The following is a list of products manufactured under the Sony Ericsson brand.Most of the models have been released under multiple names, depending on region of release, currently usually indicated by a letter added to the end of the model number ('i' for international, 'a' for North America, and 'c' for mainland China), but indicated on some (mostly older) models by a slightly differing ...

Touch switches have no moving parts and electronically switch the light circuit. As of 1986 [update] these remain specialty items. Electronic switches provide flexibility in terms of different interfaces for their operations, such as touch plates, soft-touch controls, pressure or light sensor-based control, interactive touch-screens (which are ...
The on-cell touch method is also limited to the size of the LCD panel, whereas sensor-on-lens modules can be larger than the underlying LCD panel, providing room for dedicated touch points that are found on many smartphone designs. Due to how sensor-on-lens modules are manufactured, the sensors are very fragile in comparison to on-cell modules.
The Pixel 7a includes dual rear-facing cameras. The wide 26 mm f/1.9 lens has a 64-megapixel sensor, while the ultrawide 120° f/2.2 lens has a 13-megapixel sensor; the front-facing camera uses a 13-megapixel sensor. It is capable of recording 4K video at 30 or 60 fps.
In 1937 W.B. Schulte, [2] McGall's employer, started the company MICRO SWITCH. The company and the Micro Switch trademark have been owned by Honeywell Sensing and Control since 1950. [3] The name has become a generic trademark for any snap-action switch. Companies other than Honeywell now manufacture miniature snap-action switches.
