For products that don’t require direct user feedback, non-tactile membrane switches are easy to incorporate and very reliable. Simple design specs also place few restrictions on the shape and size of keypad components.
Non-Tactile
Tactile
Operators often prefer the user feedback of domed tactile membrane switches. This can be accomplished with stainless steel or polydomes.
PCB Backing
Printed circuit boards can be used as the foundation that lies under the graphic overlay, as opposed to the polyester circuit, to provide maximum reliability when integrating multiple components.
