2. Miniature snap-action switch - Wikipedia

   en.wikipedia.org/wiki/Miniature_snap-action_switch

   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.

3. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed.

4. RF switch - Wikipedia

   en.wikipedia.org/wiki/RF_switch

   An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF (radio frequency) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT). Incorporating a switch into a switch matrix system enables you to route signals ...

5. Radio-frequency microelectromechanical system - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_micro...

   A capacitive fixed-fixed beam RF MEMS switch, as shown in Fig. 1(a), is in essence a micro-machined capacitor with a moving top electrode, which is the beam. It is generally connected in shunt with the transmission line and used in X- to W-band (77 GHz and 94 GHz) RF MEMS components. An ohmic cantilever RF MEMS switch, as shown in Fig. 1(b), is ...

6. List of RF connector types - Wikipedia

   en.wikipedia.org/wiki/List_of_RF_connector_types

   Air cored Microwave connectors The name of a connector (e.g. 1.85) is determined by the diameter in mm of the air dielectric around the centre pin 3.5 and 2.92 mm (sometimes called K) connectors, which also have a 0.9mm centre pin and cross-mate with SMA and offer higher maximum frequency

7. Switch - Wikipedia

   en.wikipedia.org/wiki/Switch

   Switches can be designed to respond to any type of mechanical stimulus: for example, vibration (the trembler switch), tilt, air pressure, fluid level (a float switch), the turning of a key , linear or rotary movement (a limit switch or microswitch), or presence of a magnetic field (the reed switch). Many switches are operated automatically by ...
