Why is it important for the switch of the circuit to be open at the start of an activity?

If you mean by activity, working on an electrical circuit, then it is for safety reasons that a switch is opened. Most companies now use a proper lock out procedure so that everyone is aware that the circuit has been locked out. If more than one person is working on the circuit each person is required to have their own personal lock on the open switch.

The device which disconnects the start winding in some split-phase motor circuits after a preset speed is obtained is the?
It is called a centrifugal switch. The switch is in series with the start winding. When the RPM of the motor reaches a certain speed the switch drops the start winding of the motor out of the circuit.
When an open motor gets up to speed what switch takes to start winding out of the circuit?
Usually a centrifugal switch. When the rotor reaches proper speed, the weights fly out and move a set of contacts so they are disconnected, thereby disconnecting the starting circuit.
What is the function of a switch in a electric circuit?
A switch is a device which can be used to make or break a circuit. If that circuit carries a voltage which would be dangerous to people or animals then the handle of the switch must be made of a good insulator and the rest of the switch must be well shielded to stop anyone - or anything else - from touching any live wires. If you get a chance to visit a science museum ask them to show you a "knife switch". Another place to see one is the Physics Lab at your local college or high school. Once you have seen a knife switch you will understand exactly how a basic switch works. It's quite simple really
What are the examples of electronic tools and equipments and their functions?
One example of a circuit device is a switch. It is used to stop and start current flow in a circuit.
What is used on a single phase induction motor to disconnect the start winding after the motor starts?
A centrifugal switch, once the motor reaches near run speed, centrifugal force causes a set of contacts to open and disconnect the start capacitors. Some larger motors use a contactor which is disconnected by the centrifugal switch.

Why is an switch important in a circuit?
Electric switch is very important because as you known that all the equipment we are using is useless without a switch. For example, if someone want to turn on its computer, it have to first on the switch without switching on the power supply is not gone in the equipment we using.
When does electricity start to flow?
When the electrical circuit is completed - usually by closing a switch.
What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.
What is happening when a switch is off?
When the light switch is turned on and a light bulb is connected in the circuit a current will flow through the circuit. Likewise when the switch is opened, the current will stop flowing in the circuit.
Why does a switch make a light turn on and off?
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
How can you start and stop electric circuit?
Using a switch device which starts and stops the electric current around the circuit
How does a 3000gt neutral safety switch work?
a neutral safety switch only allows the car to start when the gearshift is in park or neutral. It is normally located on the top of the transmission. the switch closes the circuit so power can be sent to the starter circuit.
Is 160 ohms reading on a switch bad?
For a switch the reading should be in the zero ohm range. Corrosion or pitted contacts will start to raise the resistance rating on a switch. This size of rating on the switch will start to raise the temperature of the switch because the switch starts to act like a load in the circuit.
What are switches used for in a circuit?
A switch is a means of making (on) or breaking (off) an electrical circuit.
Whats the function of rx7 neutral switch?
My 1987 RX7 GXL automatic is getting its' THIRD Neutral Safety Switch, also called the Inhibitor Switch. The switch allows the starter circuit to start the car if the gear selector is in P or N. If the selector is in any other gear the circuit will not open and the car will not start. Sometimes the switch can be "adjusted". Most of the time it is replaced for about $435 part and labor.
