Electrical Contacts
PESSRL Manufactures high quality Electrical Contacts with high electrical conductivity, good erosion resistance and anti-welding using three integrated technologies: Cold Forging, Internal Oxidation and Powder Metallurgy.
A well-equipped workshop with cold headed machines, we manufacture millions of Solid, Bi-metal and Tri-metal Electrical Contacts.
We offer these rivets in a variety of head profiles—including Flat, Radius, Dome, Square, Spherical, and Hexagonal—to suit diverse application requirements.
Electrical Contacts
Our solid rivets are produced from carefully selected Silver-alloys or Electrolytic Grade Copper using advanced high-speed cold forging technology. This ensures uniform quality, stable electrical properties, and long service life. These rivets provide excellent conductivity and dependable performance even in demanding environments.
Our Bi-Metal Rivets are manufactured with a precision-formed silver alloy contact surface bonded to a high-grade electrolytic copper base. This combination delivers outstanding electrical performance while ensuring excellent mechanical stability.
As one of the leading producers of bi-metal contact rivets, we take pride in delivering products that balance innovation, efficiency, and durability. Each rivet is crafted through a controlled metallurgical bonding process that permanently unites the silver alloy head with the copper shank. This construction provides excellent conductivity, reduced thermal resistance, and long service life even in demanding electrical environments.
The bi-metal architecture is designed to optimize material usage by reducing silver consumption makes our rivets not only a technically superior option but also a highly economical solution for applications such as switches, relays, circuit breakers, and other electrical contact systems.
Our Tri-Metal Rivets are engineered for demanding applications that require dependable double-sided contact. These rivets feature a layered composite structure: a top contact surface made of a silver-alloy, a central core of high-conductivity copper, and a bottom contact layer also clad in silver alloy.
Thanks to this style of architecture, they combine the outstanding electrical conductivity and arc-resistance of silver alloy with the thermal dissipation and cost-efficiency of copper. Because both ends (head and shank) are finished with the high-performance contact material, these rivets excel in applications requiring dual contact — such as double-headed moving contacts in relays, switches, or contactors.

Electrical Button Contacts
Bimetal Button Contacts
Button Contacts are manufactured with a precision-formed silver contact surface bonded to a Electrolytic Copper or Cupro-Nickel base. Each contact undergoes special hardening and surface-enhancement processes to ensure the silver layer is highly wear-resistant and capable of maintaining stable electrical performance over extended use.
The choice of Electrolytic Copper or Cupro-Nickel at the base provides excellent weldability, allowing the contacts to be securely welded onto a wide range of contact carriers. To simplify assembly, the contacts are designed with welding projections that promote quick, reliable attachment — even when the supporting base material is thin.
Button contacts can be produced in multiple sizes as per application needs.
Contact Assemblies
Contacts are riveted onto the moving contact carriers and terminal contacts using semi-automatic or fully automatic riveting systems. The riveting method is selected based on the customer’s production volume, application needs, and performance requirements, ensuring optimal consistency and efficiency in assembly. Brass, Copper and Bronze with Silver Plating depending on customer requirement.
Silver or silver-alloyed contacts are brazed to copper, brass, or steel substrates using furnace, induction, flame, or resistance brazing methods, selected based on demand, complexity and specific application needs—using a controlled application of heat and filler metal.
Resistance brazing offers controlled heat input and repeatable joint quality, making it suitable for both simple and complex assemblies across electrical and power distribution equipment. Silver brazed joints are widely recognized for producing strong, mechanically robust, and corrosion-resistant bonds with excellent electrical conductivity, especially where heat distortion must be minimized.
This process produces exceptionally strong, highly conductive joints capable of withstanding demanding electrical and thermal loads, making them ideal for high-power environments including circuit breakers, relays, motor starters, and industrial switching systems.
