What is the different between contactor and relay?
A contactor, as far as being used to start a motor or the like, is in essence, a relay. A coil is energized and the normally open contacts from the contactor close (normally 3 contacts for an AC motor) and the motor starts. Do I understand your question? Or are you trying to decifer the difference between the coil of a relay and the contacts of a relay?
What is the set of contacts actuated by magnetic coil?
Relay
What is close contact relay?
A relay is an electrical switch. It consists of a electromagnetic coil and a set of mechanical contacts. Depending on the relay their could be multiple sets of mechanical contacts. The close contact lets current flow through the mechanical contacts when the relay is not turned on. When the relay is turned on current flow is stopped. This is called a normally closed contact or NC The open contact works the opposite of the closed and is referred to as a normally open contact or NO
How does a contact relay weld?
Too much current cause excessive heat and cuases melting of the relay contacts.
What happens if you wire the relay contacts in series with the relay coil and apply voltage?
The relay will turn on and off, usually so fast that it forms a buzzer.
