The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float. Another common type is a float that raises a rod to actuate a microswitch. One pattern uses a reed switch mounted in a tube; a float, containing a magnet, surrounds the tube and ...
Notes in it include a prime symbol below the note's letter. Names of subsequent lower octaves are preceded with "sub". Notes in each include an additional prime symbol below the note's letter. The octave starting at tenor C is called the "small" octave. Notes in it are written as lower case letters, so tenor C itself is written c in Helmholtz ...
They are also used in electronic music, for instance to impart a random quality to successively-played notes. A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET (field effect transistor) switch and normally one operational amplifier.

Switching circuit theory is the mathematical study of the properties of networks of idealized switches. Such networks may be strictly combinational logic, in which their output state is only a function of the present state of their inputs; or may also contain sequential elements, where the present state depends on the present state and past states; in that sense, sequential circuits are said ...
Hymn-style arrangement of "Adeste Fideles" in standard two-staff format (bass staff and treble staff) for mixed voices Tibetan musical score from the 19th century. Sheet music is a handwritten or printed form of musical notation that uses musical symbols to indicate the pitches, rhythms, or chords of a song or instrumental musical piece.
(from top) Single-pole reed switch, four-pole reed switch and single-pole reed relay. Scale in centimeters. A reed relay [i] is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them.
A simple on-off switch. The two terminals are normally connected together (closed) and are open when the switch is activated. An example is a pushbutton switch. SPDT Form C [4] Single pole, double throw: Two-way: Three-way: A simple break-before-make changeover switch: C (COM, Common) is connected either to L1 or to L2. SPCO SPTT, c.o. Single ...
The central melody of "Simple Gifts" is used in the 2009 song The Sound Above My Hair by German electronic music group Scooter, which utilises bagpipes in the composition. The 2008 song " The Greatest Man That Ever Lived (Variations on a Shaker Hymn) " by Weezer makes extensive use of the "Simple Gifts" melody throughout.
