For a greater range of design features, Eastprint produces many switch
assemblies utilizing rigid printed circuit boards. All of the features
of a membrane switch assembly may be integrated into this type of construction
with the addition of through-hole and SMT components.
Some of the design parameters met using PCB keypad assemblies include:
 Keypads
which utilize mechanical switch, metal dome, Push Gate™ or conductive
rubber switch contacts- Multi-layer PCBs incorporating screened graphic overlays or molded
silicone rubber keypads
- PS/2 interfaces, electronic modules and backlighting inverters
- Rubber keypads with conductive carbon pills that contact the PCB directly,
or keypads with plastic actuators used to contact electro-mechanical
switches
- Hybrid designs combining flexible top circuits with PCBs
- Environmental sealing enabling the backlighting of rubber keypads
and assembly of electronic components available only with PCBs
Design options include various connectors, mounting hardware, flat panel
displays, backlighting methods, tactile feel options, surface-mounted
or traditionally mounted electronic components, and a wide variety of
graphic overlay options.
