Switches Catalog

In electronics, a Switch is an electrical component which can break an electrical circuit, interrupting the current or diverting it from one Conductor to another.[1][2] The most familiar form of Switch is a manually operated electromechanical device with one or more sets of electrical contacts. Each set of contacts can be in one of two states: either 'closed' meaning the contacts are touching and electricity can flow between them, or 'open', meaning the contacts are separated and nonconducting. Since the advent of digital logic in the 1950s, the term has spread to a variety of digital active devices such as transistors and logic gates whose function is to change their output state between two logic levels or connect different signal lines, and even computers, network Switches, whose function is to provide connections between different ports in a Computer network.[3] The term 'switched' is also applied to Telecommunications networks, and signifies a network that is circuit switched,
