Relays that use a Make Before Break (MBB) system of contacts, i.e. both separate contacts are connected to the common contact as the change over takes place.

What is meant by double pole as related to electromechanical relays?
A double pole relay has two independent and isolated contacts. Each of these poles can operate individual circuits. There are three types of relay poles Form A relays are SPST with a default state of normally open. Form B relays are SPST with a default state of normally closed. Form C relays are SPDT and break the connection with one throw before making contact with the other (break before make). When the relay coil is energized these contacts reverse. The closed contact opens and the open contacts close.

What happens if you energize power to wire on n.c. contacts?
If the relay contacts are in series with a connected load, then the load will energize.
What does 3 form C mean when related to contact arrangements of a control relay?
A single "form-C contact" means a set of three terminals, where the middle one connects to one of the ends when the relay is energized, and connects to the other one when the relay is de-energized. "3 form-C" means there are three separate individual sets of form-C contacts on the same relay. There's no connection between the sets, but when the relay is switched on or off, they all flip from one side to the other at the same time.
How do relay contacts become pressed together when a current passes in the coil?
Relay contacts change state (become pressed together) when a current passes through the coil because that current causes a magnetic field to be induced which attracts the armature, to which is attached the contacts.
How does a contact relay weld?
Too much current cause excessive heat and cuases melting of the relay contacts.
