wire form pins &
spring contacts
Built for consistent shape, force, and engagement.
Small wire-formed components can have a big effect on electrical contact, retention, grounding, and assembly fit.
Gromax supports precision wire form pins, spring contacts, grounding contacts, retention pins, and formed-wire components used in electrical, electronic, medical, industrial, automotive, sensor, and molding-integrated products.
Spring Contacts
Precision contacts designed to provide repeatable electrical engagement through controlled spring force and deflection.
Formed Wire Contacts
Conductive wire forms designed to establish and maintain electrical connection between mating components.
Battery Contacts
Spring-loaded wire contacts designed to provide consistent electrical engagement in battery-powered products.
Grounding Contacts
Formed wire components used to establish grounding paths and electrical continuity inside assemblies.
Connector Contacts
Precision wire forms used inside connector systems to support signal transfer, retention, and electrical performance.
Contact Springs
Wire-formed spring elements used to maintain electrical continuity, grounding, mechanical preload, or contact pressure.
Wire Form Pins
Precision-formed wire components used for alignment, retention, positioning, and mechanical engagement inside assemblies.
Retention Pins
Wire-formed pins engineered to secure, locate, or retain components while supporting repeatable assembly.

common applications
Wire forms and spring contacts are used where spring performance, retention force, electrical continuity, and repeatable geometry affect product reliability.
High-Volume Wiring Device
Wire forms, spring contacts, stamped mounting straps, grounding clips, terminal features, and formed copper-alloy contact members are common fit points in receptacles and wiring devices.
Consumer Electronics Charging Case
Spring contacts, battery contacts, charging contacts, grounding springs, shield clips, connector contacts, and small retention forms are realistic fit points in compact consumer electronics.
Counter-UAS / Anti-Drone System
Wire forms, spring contacts, grounding clips, RF shielding contacts, connector retention features, board-level contacts, rugged power contacts, and antenna-related conductive features may be used inside counter-UAS systems.
Terminal Block Relay
Wire form pins, spring contacts, relay contact features, terminal springs, lead-frame elements, and formed conductive components support signal switching, isolation, terminal engagement, and compact electrical connection in automation panels and machine-control systems.
Wearable Glucose Sensor
Spring contacts, battery contacts, sensing contacts, grounding features, shield clips, antenna-related conductive components, and small retention forms may support compact wearable medical electronics.
Industrial M12 Cable Assembly
Spring contacts, wire contacts, stamped terminals, crimp features, grounding elements, and formed conductive components can be positioned inside molded or overmolded connector bodies to create sealed, ready-to-plug connections for industrial sensors, I/O modules, field devices, and automation networks.
when
GROMAX
is a good fit
Bend Geometry Must Stay Consistent
Multiple bends, hooks, loops, offsets, and contact features can be difficult to hold if the forming sequence isn’t controlled.
Spring Force Matters
The part may need consistent:
• Preload
• Deflection
• Contact pressure
• Retention force
• Fatigue resistance
• Resistance to permanent set
Wire Diameter And Material Matter
Wire diameter, material, temper, and finish affect:
• Springback
• Strength
• Conductivity
• Corrosion resistance
• Fatigue life
• Formability
Cut-End Condition Affects Fit
Cut length, end shape, sharp edges, and deformation can affect insertion, contact, handling, and mating-part wear.
Electrical Performance Must Stay Stable
Conductive wire forms may need reliable contact pressure, low resistance, and consistent grounding through repeated use.
The Part Fits Into A Larger Program
Gromax is often a stronger fit when the wire form is tied to a broader stamped, plated, assembled, or overmolded component program.
