An electrical switch is a device that allows diverting or interrupting the course of an electric current. In the modern world its types and applications are innumerable, from a simple switch that turns off or on a light bulb, to a complicated multi-layer automatic transfer selector, computer controlled.
Its simplest expression consists of two stainless metal contacts and the actuator. The contacts, normally separated, are joined by an actuator to allow current to circulate. The actuator is the mobile part that in one of its positions puts pressure on the contacts to hold them together.
Types of switches:
double switch: it´s that switch that is used to contral is two consumers or two groups of consumers independent of cach other.
The double switch provides you with a single mechanism withe two buttons.
Three Way: Three way switches are two swichr with a common point, used to manipulate a bulb from in big houses.
Four Way: it has some function as the first one, but now throgh this system you can manipulate a bulb from three diferent places. this is due to the conection betwen switches at certain points that close the circuit together.
Dimmer: A Dimmer, regulator, dimmer or dimmer, serves to regulate the energy in one or more light bulbs in order to vary the intensity of the light they emit, when the lamp properties make it possible.
Some dimmer can be controlled remotely through special controllers and protocols. In the case of stage lighting one of the most used protocols is DMX (Digital MultipleX), which is a communications protocol used to control stage lighting, or DMX512, which allows the intensity of conventional lights to be synchronized with special effects lights, smoke machines, etc.
Circuit Breaker: It is a device capable of interrupting or opening an electrical circuit when insulation failures occur in an electrical equipment or installation. It should not be confused with a thermomagnetic switch because, unlike this, the circuit breaker opens the circuit when there is a difference between the incoming and outgoing currents of the circuit. Its main objective is the safety of people, preventing them from being affected by electric currents when coming into contact with the equipment in failure. Unlike the fuses, which must be replaced after a single use, the circuit breaker can be reset once it has been located and repaired the problem that caused its trip or automatic deactivation.
