In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.
The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts, which are connected to external circuits. 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 the switch is nonconducting. The mechanism actuating the transition between these two states (open or closed) can be either a "toggle" (flip switch for continuous "on" or "off") or "momentary" (push-for "on" or push-for "off") type.

This 3D tutorial covers SPST, SPDT, DPST, and DPDT switches. Shown in the video is how DPDT switches may be used as a 4-ways, DC motor reverse switch, and a power transfer. Also covered Normally Open, Normally Closed and the common terminals mean. This my first tutorial made using Blender. Audio was recorded using Audacity and the video was edited by Avidemux. All work was done in Ubuntu Linux.

You want her don't you?
All those past mistakes you've rued
Well, look who lost the gold
And rather you than me, cus the view I can see is
heaven, heaven to hold
Hey you, give up the ghost cus I'm the one that she
loves the most
And although you've tried she's forever tied to me
And hey man give up your band cus I hold your pen in my
silver hand
And your never close so, give up the ghost
Give up the ghost
Did she ever need you?
Or did you bid a fond adieu
Oh it's left me feeling cold
Well let your lesson be learned
Cus the tables have turned, as our sea sick drama
unfolds
Hey you, give up the ghost cus I'm the one that she
loves the most
And although you've tried she's forever tied to me
And hey man give up your band cus I hold your pen in my
silver hand
And your never close so, give up the ghost
Give up the ghost
Pedros, give up the ghost cus I'm the one she loves to
host
And although we've cried she's never lied to me
He-Man give up your band, cus I hold your sword in the
silver sand
And you're never close so
Give up the ghost
