How can I choose the best electronic switch?

The selection of the best electronic application switch requires to know what kind of load can handle, how long the operative switch will meet, what regulations meets, and the type of environment in which it can work. Another way to select the switch, you can see the evaluation type given to the Laboratory subscriber (UL) or the level of the Ingress Protection (IP) specified by the international electrical engineering). Electronic switches are mounted in different ways, including surface mounts, soldering or fast connection design. Some may not be able to cope with soldering temperatures, while the necessary size affects the choice, because so many components must be suitable for small plates with circuits even home electronics. If it is evaluated too low, the power supply can shorten the device and the switch will not work. Too high ranking could make the ficier inefficient and unnecessarily expensive. Mechanical contact functions are not relevant because electronic switches contain bipolar connectionsby Achi transistors or transistors of the effect in the field. One must know the evaluation of these components, which are usually listed in the product specifications.

Life expectancy is another problem. Depending on the quality, the switch may be cheaper, but later on maintenance and replacement, especially if it is mounted on the circuit board. The electronic switch may also have to work in the presence of humidity, high temperatures or dust depending on where it is used. Building electronics are usually located in a controlled environment, but electronic switches used for industrial systems, medical devices and construction equipment are often exposed to elements.

IP switch rating shows how it is protected. For example, the IP 65 rating means that the electronic switch can be used where there is dust in the air and where there is a direct exposure of water. If IP 67 is evaluated, the switch can be submerged into VODY, while lower rating, such as IP 60 average water exposure, would damage the device, but the dirt will not get in. All IP reviews determine how well any electronic cover is sealed. The size of the electronic switch is also important, as whether it is standard, miniature or ultra-miniature switch affects inclusion in the overall electronics design.
