would very much appreciate knowing the answer to this question

Thank you in advance for any help

<P>A standard American symbol is a small closed circle with four (4) radial line segments extending outward from the perimeter at 45,135,225,315 degrees. Wire connection is generally, but not always, made along the horizontal diameter at 180 and 0 degrees.</P>

Circle with 4 short lines around the outside of the circle radially located at 45, 135, 225 and 315 degrees, two power lines at 90 and 270
degrees, and the color designation (single letter) in the center of the circle.

This is a bit difficult to describe in words, but I will attempt it. A pilot light is a circle with four lines radiating from it at the angular orientations of 45, 135, 225, and 315 degrees. The lines are entirely outside the circle. It is usually easiest to draw this by starting with vertical and horizontal lines, and then rotating them 45 degrees.
The lines do not touch the circle, and the length of each is slightly less than the radius of a circle twice the diameter of the original one (whatever looks good). The centre of the circle has a letter corresponding to the
colour of the light (R for red, B for blue, A for amber, G for green, etc.).

When the pilot light is part of an illuminated push button, it is conventional to link the two with a dotted line.
