The electronics industry produces a great deal of switches like Carling rocker switches, toggle switches, pressure switches, selector switches and many more. In fact, there are a number of different switches in operation today and this can confuse the novice electronics or electrical enthusiast. Here is more about rocker switches and other types to help eliminate some of the confusion.
The Switching Process
To switch means to direct from one source to another or to simply change. A switch can turn something off or redirect power to another source. For example, a simple household 3 way switch toggles power from one traveler wire to another. This allows the home occupant to turn off a light from two separate locations.
The fundamental design for most switches is very similar. However, the mechanism which accomplishes the switching can vary drastically and this is why we have so many types of switches accomplishing a wide variety of tasks in electrical circuits today.
Toggle Switches
A toggle or lever is used to throw the switch. This is how common single pole wall switches in your home work. Flip it up and power flows from one terminal to another, completing the circuit and turning on a light or fan. Flip it off and the connection is broken (and you could be in the dark).
Rocker Switches
Rocker switches have a simple mechanism which rocks back and forth in two positions, “on” and “off”. They can be used for wall switches or in electronics applications (Carling rocker switches for example).
Rocker switches provide important benefits. For instance, they are not easily accidentally turned on or off, and if something is moved about or dropped, it is less likely to throw the switch. In addition, components like Carling rocker switches can be illuminated and this makes them easier to identify.
Push Button Switches
Push button switches are activated by a spring loaded button. They can be momentary contact or some have a mechanism which alternate between on and off each time the button is pushed. Push button components take up little space and are simple to operate.
More Switches
Here are more switches you will find today:
* Selector switches – a lever connecting two sets of contacts can be thrown to engage two different sets of contacts. This can be used for simple speed control.
* Pressure switches – liquid or gas is used to create pressure in a diaphragm which throws a switch. These switches are often used for simple timers and pressure regulation.
* Temperature switches – used in heating and cooling applications. A heat sensitive metal spring reacts to heat pushing up on a contact to close it (normally open). The spring can also be used to break contacts (normally closed).
These are only a few of the many applications you can find components like Carling rocker switches working hard today.
