NLS DTBM Breath Switch

The Library of Congress, National Library Service for the Blind and Print-Disabled, is seeking a single award for a five-year Indefinite-Delivery, Indefinite-Quantity (IDIQ) firm-fixed-price contract to develop and manufacture USB breath switches. These devices allow patrons with physical limitations to control Digital Talking Book Machines (DS-1, DA-1, and DA-2) using air pulses. The project is divided into two phases: a non-recurring engineering phase and a full-production phase. The contractor is responsible for developing the device, which includes a microcontroller, circuitry, USB-A connector, and food-safe silicone tubing, as well as a comprehensive Technical Data Package consisting of 3D CAD models, electronic schematics, and software source code. The contract period of performance runs from February 25, 2027, to February 24, 2032, with a total duration not to exceed 66 months. Quality standards are stringent, requiring ISO 9001:2026 certification and adherence to ANSI/ASQ Z1.4 sampling procedures with an acceptable quality level of 0.40 percent nonconforming. Technical requirements include compliance with USB Specification Revision 2.0 and UL 60065 safety standards, with power limited to 2.5 Watts. Proposals are evaluated based on technical approach, corporate experience, and price reasonableness. Submissions must be delivered via email by November 25, 2026, and must follow specific volume and formatting guidelines.
