The switch panels produced by Stamford Engraving are made from a laminate sometimes called Traffolyte or Formica. The material is available in a range of colours in thicknesses of 1½mm and 3mm.
Switch panels are usually made to the specifications of a customer's drawing. The positions and diameters of the holes are accurately measured according to the drawing's instructions. The area immediately around the holes is left clear of text if indicated.
Stamford Engraving can produce switch panels up to a size of 600mm (2ft) wide by 375mm (14¾in) high.
