11Crossbar switch — In electronics, a crossbar switch (also known as cross point switch, crosspoint switch, or matrix switch) is a switch connecting multiple inputs to multiple outputs in a matrix manner. Originally the term was used literally, for a matrix switch… …
121ESS switch — The Number One Electronic Switching System, the first large scale Stored Program Control (SPC) telephone exchange or Electronic Switching System in the Bell System, was introduced in Succasunna, New Jersey, in May 1965[1]. The switching fabric… …
13Wire spring relay — A wire spring relay is a type of relay, primarily manufactured by the Western Electric Company for use by the Bell System in electromechanical telephone exchanges. It was licenced for use around the world, and was commonplace in Japan. A wire… …
14RF Switch Matrix — or Microwave Switch Matrix or Switch Matrix An RF/Microwave Switch Matrix is used in test systems, in both design verification and manufacturing test, to route high frequency signals between the device under test (DUT) and the test and… …
15Panel switch — The panel switching system was an early type of automatic telephone exchange, first put into urban service by the Bell System in the 1920s and removed during the 1970s. The Panel and Rotary systems were developed in parallel by Bell Labs before… …
16Centralized traffic control — (CTC) is a signalling system used by railroads. The system consists of a centralized train dispatcher s office that controls railroad switches in the CTC territory and the signals that railroad engineers must obey in order to keep the traffic… …
17Reed relay — A reed relay is one or more reed switches controlled by an electromagnet. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them. Sealed in a long, narrow glass tube, the… …
18Analogue switch — The analogue (or analog) switch, also called the bilateral switch, is an electronic component that behaves in a similar way to a relay, but has no moving parts. The switching element is normally a MOSFET, which is a type of transistor. The… …
19Reed switch — Reed relay and reed switches Showing the contacts clearly The …
20Stepping switch — In electrical controls, a stepping switch is an electromechanical device which allows an input connection to be connected to one of a number of possible output connections, under the control of a series of electrical pulses. They could step on… …
