Controller Service & Sales Co Inc.

Controller Service & Sales Co Inc., the Controller Service & Sales division, supplies specialized electronic components and control equipment for naval and maritime defense applications as a prime contractor to the Defense Logistics Agency and Naval Sea Systems Command, competing exclusively in full-and-open procurements with no set-aside designations except for two Total Small Business awards. The company is a for-profit Massachusetts-based defense contractor headquartered in Avon with active SAM registration since June 2000, operating across multiple NAICS categories centered on relay and industrial control manufacturing (334413, 335314, 334519) and electrical component supply.

The vendor's federal work consists entirely of component procurement — electromagnetic relays, magnetic contactors, motor starters, solid-state relays, thermal heaters, switches, fuses, circuit breakers, coils, transformers, and related electrical and electronic hardware. Representative work includes a $160,616 motor starter purchase order from the Defense Logistics Agency Land and Maritime (August 2025), a $127,860 magnetic contactor order from DLA Land and Maritime (August 2025), a $126,490 electromagnetic relay order from DLA Land and Maritime (August 2026), and a $98,200 magnetic contactor procurement from DLA Land and Maritime (March 2026), all firm fixed-price, all performed at the Avon facility. Naval Sea Systems Command has placed recurring small purchase orders for push switches, control stations, rotary selector switches, and related naval equipment, including a $23,100 Total Small Business award for a 3-position rotary selector switch (March 2025). The vendor also holds single-award indefinite-delivery contracts with DLA: seven IDICs with ceilings ranging from $250,000 to $350,000 each (thermal heaters, electromagnetic relays, coupler fluid, thermal relays) awarded between September 2025 and May 2026, each carrying one-year performance periods or until ceiling reach.

Customer concentration is pronounced and heavily skewed to DLA Land and Maritime. The top three customer agencies account for 96% of recent awards by count, led by Defense Logistics Agency Land and Maritime (67 awards, $3.3 million combined potential value), Naval Sea Systems Command (10 awards, $89 thousand), and Defense Logistics Agency Aviation (8 awards, $31 thousand). DLA Land and Maritime dominates both volume and dollars; Naval Sea Systems Command places high-frequency small orders ($5,700 to $23,100 range) with extended delivery periods. The vendor's top parent vehicles are two single-award IDICs (SPE7M126D60LD with 3 task orders; SPE7M526D60QG with 1 task order and $6 thousand combined potential value).

Activity has accelerated sharply — one award in 2022, two in 2024, 32 in 2025, and 47 in 2026 year-to-date — with fourteen awards (combined potential value $315 thousand) reaching ultimate completion within the next twenty-four months, representing recompete exposure concentrated in DLA Land and Maritime indefinite-delivery and purchase-order work. The vendor's product and service category footprint clusters on relay and industrial control manufacturing (19 awards), other electronic component manufacturing (17 awards), and switchgear apparatus manufacturing (10 awards), with PSC codes tracking to switches (23 awards), relays and solenoids (19 awards), and electrical control equipment (12 awards). All awards are prime contracts; no subcontract activity appears in the source data. Across the footprint, the vendor competes under full-and-open procurement rules; only two Total Small Business set-aside awards (March 2025 NAVSEA selector switch; September 2025 DLA electromagnetic relays) appear among the 93 awards listed.
