Potential free contacts (also called "dry contacts") are simply contacts which are physically operated with the main device, but not electrically connected to it. For example a motor contactor often has auxiliary contacts that are operated by the main coil and open and close at the same time as the main contacts but are not used for control of the motor starter. If they are connected to an outside circuit to indicate the status of the starter without being powered by the motor supply they would be considered potential free contacts.

These type also called Signal-Contacts.

In case of relays and switches if the common/pole is connected internally to a given potential like a 110V phase etc., the contact is not POTENTIAL FREE but if both the common and the normall open (and at time also the normally closed) contacts are presented to the user for connecting in his system as he pleases,the contact is said to be "potential-free".

What is contact potential in junction diodes?

The contact potential of a pn-junction diode is signified by the turn-on or barrier voltage, which is the voltage beyond which non-negligible current con be measured flowing in the forward-bias direction. To put it simply, one can run a variable potential difference across a diode in it forward-bias direction until one measures a current. That is the contact potential of the diode. Theoretically, the contact potential is a function of the temperature and doping concentration, and intrinsic hole-electron pair concentrations. However, in the real world, there maybe other factors that will affect the contact potential of a diode.

What is a free website to do criminal background checks?

There are no safe websites where you can get free criminal background checks. You should contact your local courthouse and file for a criminal background check, as you might for potential employees. Sites that provide this service for a fee are generally not reliable or accurate.


Why own a website?
