 If you have a button, and two different glyphs,

 if on
 BitBtn1.Glyph.LoadFromFile('on.bmp')
 else
 BitBtn1.Glyph.LoadFromFile('off.bmp')


OR

var
 ONBMP, OFFBMP: TBitmap;

if On
 BitBtn1.Glyph.Assign(ONBMP)
else
 BitBtn1.Glyph.Assign(OFFBMP)

or if you have the images in a TImageList


if On
begin
 ImageList1.GetImage(0,ONBMP);
 BitBtn1.Glyph.Assign(ONBMP);
end
else
begin
 ImageList1.GetImage(1,OFFBMP)
 BitBtn1.Glyph.Assign(OFFBMP)
end;

Note for this example you will have two glyphs (same size) in your ImageList
(ImageList height & width properties set to glyph height & width)

The Off image at index 0 and the OnImage at index 1 in the image list.

then

Create a BitBtn,

assign the Off bitmap to its Glyph property

set its caption to 'Off'

then place the folowing code in its OnClick event


procedure TForm1.BitBtn1Click(Sender: TObject);
begin
 BitBtn1.Glyph:= nil; //clear glyph
 if BitBtn1.Caption = 'ON' then
 begin
  ImageList1.GetBitmap(0,BitBtn1.Glyph); //get Off image
  BitBtn1.Caption:= 'OFF'; //set caption to off
 end
 else
 begin
  ImageList1.GetBitmap(1,BitBtn1.Glyph);//get ON image
  BitBtn1.Caption:= 'ON';//set caption to on
 end;
end;

yes mokule,  you could do it that way, but you would have to distribute the images with your application. If you have them in the imageList, they are already in the application.....

Another way, would be to have the images in the resource file, then load the bitbtn from the resource file....
