Electronics - Voltage and Current - Discussion

@Anusha:
U get it na, that SPDT hav one input and Two output lines. The best example of SPDT is Relay. I will giv u bettr example, assume that u have relay of 6v, it hav two output normally open and normally closed. Relay hav its main input connectd to that normally closed terminal. Assume u hav connected a motor to normally open terminal. And there is nothing connected to that normally closed terminal. When u giv voltage upto 5.8v to relay, ur motor will not run. But as u giv voltage to relay of 6.1v ur motor which is connected to normally open terminal, will start to run. This is how relay works with the best example of SPDT swicth.

Thanks sourav for the answer.

But can you tell me in the example you mentioned above, if another motor is also connected to the closed terminal of the relay (the previous motor also connected) , and we provide 6. 1volt, then which motor will turn on?

It depends on operating voltages.

@Sumita.

If we do parallel connections then we can provided 6. 1v supply to both the motors so that both can work at a time. But the problem is if you need to operate these motors separately then one should provide a switch so that we get option in-front of us, which is more suitable way.

What is push button ?

Thanks to Sourabh.

Please tell code of different type of switch.

"spdt,spst,dpst,dpdt":
What is the Correct symbol?

Simple example off push button is our DOOR BELL until we press the bell button the current can flow when we drop button current cut off.

Please differentiate SPST&SPDT?
