Some terms related to automatic swith-such liquid level switch and temperature switch came to me recently. These are quite new for me, a graduate in Materials discipline. I think these are some kinds of elements of mechanical engineering. The general defination and description of those terms are listed below when corresponding search through the Internet has been done.
Liquid level switch is mainly used in equipments which request liquid level is regularly kept unchangeably.Liquid level switch can be widely used in automobile, industry equipments, agriculture equipments and household electrical appliances.

As the saying goes, every coin has two sides. So does this one- GPS tracking technology. It is hardly to deny that high tech is a double-edged sword.
The reasons are quite obvious. For one thing, this high tech can guarantee the betterment of social security-policemen have possessed an effective and powerful weapon in avoiding of drug deal or some activities illegal. For another, people are forced to confront with this embarrassing situation—privacy being infringed and lost
Let’s move a little deeper and be more specific. What about tracking the Cops themselves? Even if I am not a cop, I can tell a cop being tracked felt like exactly a criminal being tracked. The results are same: if you want to track your employee by GPS tracking, you must undertake the consequences of the decline of the focus and efficiency. If you want to track your spouse or your kids by GPS tracking, sorry, get out! Your freak…
People always think of technology as a solution to problems, not a creator. But now they must change their mind before it is too late.
Finally, I have a question: would you like to track yourself by GPS tracking technology to show your wife or kids or your employer where you are?
