The Department of Defense, specifically the Department of the Navy, is seeking to procure five units of a variable action switch under a presolicitation notice. The procurement is set aside for small businesses, as indicated by the Total Small Business Set-Aside designation, and the item is classified under the PSC code 5930. This switch is critical for various defense applications, and the government intends to negotiate with a single source due to the lack of sufficient data to purchase from alternative suppliers. Interested parties should contact Sarah Haley at NAVSUP Weapon Systems Support for further details and must respond within 15 days to express their interest and capability to meet the requirements. The delivery location is specified as DLA Distribution in New Cumberland, PA, and the contract may include an option quantity for additional supplies.
