What is the difference between earthing boss and earthing lug and where to use?
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
What is the difference between a fail open valve and a fail closed valve?
Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.
What happens if the switch is open?
If the switch is open, current does not flow.

How a Magnetic Proximity switch works?
When metal passes in front of the switch the magnet inside either makes or breaks an electrical connection depending on if it is a normally open or normally closed type switch. When the metal is removed the switch moves back to its normal position. These are particularly useful in applications where it might be exposed to water since the switch is completely enclosed. Connected to a relay the switch can activate or stop a hydraulic valve when a part has reached its proper position.
What is a open switch circuit?
When a switch is 'open' that means it is in the 'off' position. 'Closed' means 'on'.
What position does the switch have to be in for a circuit to work?
The switch would be open.
What happens to an electric current at a light switch?
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
Where will be earthing swithing used?
there is never a switch in an earthing conductor in portable equipment the plug is constructed so that the earth connection is made first and broken last when removed
Does lamp in off position use electricity?
No. When the switch is open, off position, no current flows. The light needs current to operate.
What is the difference between chemical earthing and conventional earthing?
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
How must an electrical switch be wired to function with a device?
So that when the switch is in the open position the circuit is open and electricity cannot complete the circuit. When the switch is closed it completes the circuit and electricity flows completing the circuit and powering the device.
Why doesn't the indoor light turn on when you open your door?
There is a 3-position switch to the left of the steering column: ON, OFF, and Door-Activated. In the OFF position, the interior lights do not turn on when you open a door. It's very easy to bump the switch to the OFF position with your knee when getting in or out of the car - I have done it quite a few times.
How do you draw open and closed circuits?
It's open and closed circuit.An open circuiit is a break, or disconnection, in a circuit. It could be, for instance, a switch in the "off" position.A closed dircuit is one which is connected (to something). It may be through a switch in the "on" position.
How do you open the seat cover of vega force motorcycle?
open it in the ignition switch. turn the key counter clockwise from OFF position. Don't push it.
Is the neutral wire energized when the appliance is off?
No current flows in the circuit when the circuit is open, as in when the appliance is switched off. The voltage is on the "hot" side of the switch when it is in the open position but the neutral is not energized until the switch is closed.
Why do the intrior lights not come on when you open the door?
The interior light switch may be in the off position or the fuse is blown.
