Decades Of Experience

Potentiometer and Membrane Switch designs demand custom treatment, as each design is unique. Our corps of design engineers have combined decades of experience in the industry with the tools and the technology to make your product with the highest quality.

Quality Team Meetings

Conference calls, quality team meetings and design cross-checks all create our ISO 9001:2000 Certified quality system. We are the experts in Membrane Switch and membrane potentiometer technology.

Testing Standards

Testing standards ensure product conformity. The Spectra Symbol engineering team puts our product through millions of actuation tests. Other tests range from linearity of SoftPot or HotPot potentiometers to scratch-testing new films for Membrane Switches to coffee-submersion of circuits for a week. We test so that you don't have to.

Tests To Your Needs

Every test requires a fixture or a testing device. We match our tests to your needs. Whether it is a simple electrical circuit test or a complex resistance measurement, we will ensure your product performs to your expectations.

Process Involves Multiple Steps

The light-assembly process involves multiple steps and machines to combine layers, connect electricity and test. LED's, electropiezzo's, PCB's, fiber optic lighting and other products may be included in the final assembly.

Major Suppliers: 3M, Dupont, GE

3M, Dupont, GE are major suppliers of our product. We stock and issue materials to the floor from our inventory Department.

Custom Production

Custom production requires custom fit and cut. With our die cutting department and laser cutting capability, we can meet your demands of fast prototyping within your quality specification.

Our Core-Competency

Our core-competency is in imaging and printing. From the basic technology has sprung multiple patents and advances in the membrane field. We operate in both GV and UV inks.

UV Curing Unit

This is a UV curing unit. It is used largely to heat and harden the UV printed ink of graphic overlays and also of anti-static dielectric.

Clean Room

Numerous applications require specialty printing in the clean room. 24 hours a day, 7 days a week, HEPA-filters process the air in this room to maintain a lint-free environment.
