A relay switch runs by sending electricity through an electromagnet in order to close or open a secondary circuit. The metal arm of the secondary circuit has a spring that is overpowered by the magnetic attraction created when power flows through the electromagnet. This attraction is what affects the circuit.Know More
The basic components of a relay switch are the electromagnet, the armature, the spring and a set of electrical contacts. An electromagnet is a device that only acts as a magnet when it has power running through it. The armature is a piece of metal that must be able to interact with a magnet so that it can be moved to close or open the circuit, while the spring must be able to hold the armature in whatever position is the default for the machine. The electrical contacts are what send power through the electromagnet and the secondary circuit.
There are two types of relay switches: normally open and normally closed. Normally open is the most common sort of relay switch. A relay switch that is normally open has no power running through it when the electromagnet is inactive. When the electromagnet is activated, it pulls the armature of the secondary circuit closed. This sends power through the secondary circuit. A relay switch that is normally closed has power when the electromagnet is not activated. Activation of the electromagnet opens the circuit and stops the flow of power through the secondary circuit.Learn more about Electrical
In order to wire a two-way switch, a current tester, wire cutters, strippers, caps, a two-way switch and basic electrical knowledge are required. A two-way switch offers several benefits to the home, such as allowing one switch to control both a ceiling fan's light brightness level and blade speed.Full Answer >
A toggle switch works by using a lever to open or close an electrical circuit. Toggle switches are available in two types: maintained contact and momentary contact. Maintained switches stay in the position in which they are switched to, and a momentary switch does not.Full Answer >
There are four terminals in an intermediate switch. These change the flow of current from one circuit to another circuit. In some cases, there is straight connection between the terminals, and in others, there are crossed-over connections.Full Answer >
A double-pole switch has two connectors (poles) that can control two circuits. A double-pole, single-throw switch (DPST) turns two circuits on or off. A double-pole, double-throw switch (DPDT) manages two circuits and turns both on and off together.Full Answer >
