Custom contacts to meet all needs
NN Inc. combines our capabilities in electrical stampings to produce bus bars, terminals, and lead frames with our expertise in making electrical contacts to create contact assemblies. Solutions are available for AC or DC applications, ranging from low-voltage circuit breakers and appliance switches to high-energy distribution disconnects and tap changer contacts. Working with our engineers, NN Inc. can optimize our customers’ assemblies to meet their specific application requirements at the best possible value.
Contact And Switch Assembly What We Build
NN Inc. produces Custom low voltage and high energy contact assemblies Electrical contact Assemblies can be customized to meet our customers application specific requirements.
Low Voltage Contact Assemblies and Switches
NN Inc. can manufacture contact assemblies for various applications, including switches, circuit breakers, and shut-offs for AC and DC circuits. NN Inc. engineers design cost-effective assembly processes for both low and high-volume production.
High Energy Contact Assemblies
NN Inc. can braze and solder powder metal contacts to copper stampings and silver plating. These assemblies are routinely used in on-load tap changers, switchgear switches, and industrial power distribution circuit breakers
How We Build
NN Inc. stamping, cold-heading, and assembly capabilities enable us to create various contact assemblies. Utilizing contact rivets or powder metal contacts, we manufacture assemblies for switches, circuit breakers, and relays suitable for both AC and DC applications, as well as low or high voltage devices.
