Profile: Electro Serigraphic Products Ltd. is a manufacturer of membrane switches. We provide graphic overlays, labels, implanted led switches and printed circuit board panels. Our membrane switches provide both interface and panel graphics, combining a bespoke switch array with custom appearance in a single component. We recognize that many companies use graphic overlays over discrete sub-miniature switches to produce control panels and instrument facias. PCB panels are double sided printed circuit board as the base substrate for the membrane a higher density switch layout. Our spacer has apertures opposite the contact areas and light pressure applied to the top layer will bring opposing contacts together to complete a circuit.
