American-made industrial electrical controls for compressor applications.
Reliable. Rated. Ready.
Hubbell Industrial Controls is the industrial electrical controls division of Hubbell Incorporated, a US manufacturer of electrical products with a history spanning over a century. The industrial controls line is best known in the compressed air industry for the Class 69J pressure switch platform — a field-adaptable, heavy-duty switch designed specifically for air compressor control that has become a standard across the industry.
The 69J platform is engineered around flexibility: the unloader can be mounted on either side of the switch body and rotated to any of eight positions, which simplifies installation and reduces the tubing run required in the field. A single platform covers 1-phase and 3-phase voltages, 1-port and 4-port manifold configurations, standard and lever-unloader variants, and cut-out ranges from 80 to 175 PSI — meaning one product family handles the full range of compressor control scenarios a distributor encounters.
The 69JG and broader 69J series carry UL, CSA, and CE approvals, giving them the safety certifications required for commercial and industrial installations across North American and international markets.
Hubbell pressure switches reach SPC through its distribution network, meaning availability is tied to an established industrial controls channel — no grey-market substitutions on safety-rated electrical components.
SPC specs pressure switches as part of the full compressor control package.
Bundling Hubbell electrical controls with compressor and treatment components through SPC keeps the bill of materials on a single purchase order and a single point of accountability for the installation.
General Manufacturing → Compressor pressure control for plant air systems across all manufacturing sectors.
Automotive Manufacturing → Pressure switch control for compressors powering assembly, painting, and tooling.
Metalworking & Fabrication → Reliable pressure switching for reciprocating and rotary screw compressors in fab shops.
Construction & Infrastructure → Pressure switch replacement and OEM controls for contractor and portable compressor applications.
HVAC & Building Systems → Compressor control switching in commercial refrigeration and HVAC equipment.
Food & Beverage Processing → Certified electrical controls for compressors in food processing facility air systems. Single-phase 120V or 240V installations use the 1-phase 69J models. Three-phase 240V or 480V compressor motors require the 3-phase-rated 69J variant. Confirm the motor nameplate voltage before specifying — miswiring a pressure switch is a service call.
Single-tank compressors typically use a 1-port switch. Multi-tank or multi-line systems may need the 4-port manifold configuration to handle multiple pressure sensing points on one switch body. Confirm the number of pressure ports on the existing manifold.
Reciprocating compressors typically require an unloader valve to allow the motor to start under no load — specify a lever-unloader variant. Rotary screw compressors with their own integral unloader control generally use a standard (non-unloader) pressure switch.
