59--SWITCH,PROXIMITY
DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS MECHANICSBURG.NAVSUP WEAPON SYSTEMS SUPPORT MECH · Response deadline: Mon, 09 Nov 2026
What the government is buying
The Department of the Navy is soliciting bids for a proximity switch, a type of electrical sensing device. Proximity switches detect the presence or absence of an object without physical contact, typically using electromagnetic fields, capacitance, or other sensing technologies. In military applications, these components are commonly used in weapon systems, aircraft, naval vessels, and support equipment for position sensing, safety interlocks, and automated control functions.
This procurement falls under NAICS 335313: Switchgear and Switchboard Apparatus Manufacturing, which covers manufacturers of various electrical switches, switchgear, and related control equipment. The FSC 5930 classification confirms this is standard military supply hardware—specifically switches within the federal supply classification system for electrical and electronic equipment components.
This is a full and open competition with no set-aside program specified. All responsible sources, including large and small businesses, may submit offers.

Who can bid
Any responsible business—small or large—may bid on this unrestricted solicitation. If you manufacture or supply proximity switches and can meet the Navy's technical and quality requirements, you are eligible to compete.
For small businesses specifically: While this solicitation carries no small business set-aside, proximity switches may qualify for the Small Business Innovation Research (SBIR) or Small Business Technology Transfer (STTR) programs in related contexts. However, this appears to be a standard procurement of commercially available or military-specified hardware rather than a research initiative.
Defense contractors should ensure they are registered in SAM.gov (System for Award Management) and that their registration is active. You will need a valid CAGE code and should confirm your firm's size status in SAM if you wish to track this opportunity for future small-businessadvantage purposes.
How to put together a competitive bid
Focus on traceability and specification compliance. Navy supply solicitations for electronic components typically require strict adherence to military specifications (MIL-SPEC) or qualified product lists (QPL). Obtain the exact technical requirements from the solicitation documents to determine whether your product meets the specified form, fit, and function.
Prepare quality documentation. NAVSUP WSS procurements often require evidence of quality management systems, such as ISO 9001 or AS9100 certification, and may mandate DFARS compliance for counterfeit electronic parts avoidance (DFARS 252.246-7007). Gather your quality certificates and supplier documentation in advance.
Review packaging and marking requirements. Defense logistics contracts frequently include specific military packaging (MIL-STD-2073) and labeling standards. Non-compliance with these requirements is a common basis for rejection.
Evaluate your supply chain. Confirm your ability to source any required raw materials or subcontracted components within the delivery timeframe. Proximity switches with specialized sensing technologies or military-grade environmental ratings may have limited qualified suppliers.
Analyze pricing strategy carefully. As full and open competition, you will compete against established defense contractors and possibly the original equipment manufacturer. Review historical pricing for similar NSNs (National Stock Numbers) if available through FedBid, FPDS, or subscription services.
