Electrical contacts

Edgetech Industries LLC enjoys a long history of manufacturing tungsten copper & tungsten silver electrical contacts. Customer confidence in product quality and dependable service reflect the our ability to deliver the best quality at the right time.
Whether you require discrete silver semi-refractory contacts, silver tungsten or copper tungsten electrical contacts, cold formed rivet electrical contacts or brazed assemblies, make ETI your first point of contact.
Each electrical contact application must be analyzed on its own merits. Electrical circuit considerations, mechanical forces, environmental and service requirements (among other aspects) are relevant to the contact application. As you likely already know, similar applications often use very different materials that depend on the very specific circumstances of the application. Please call or email us with your inquiries and let ETI work for you in your search for the product, component or material that is right for your electrical contact application.

Aircraft Circuit Breakers and Relays:

Most common aircraft circuit breakers and relays require direct current, high-reliability circuit protection for control and/or enabling systems or indicating alarms.

Industrial Controls and Relays:

Devices for controlling machines, automation, process controls and indicating alarm conditions.

Load Tap Changers:

High voltage transformer applications under load experiencing moderate to severe arcing.

Reclosers: Arcing Contacts Are Required

Reclosers are electrical contact devices that eliminate contact bounce.

Vacuum Switchgear, Breakers and Interrupters:

In these types of applications, resistance to arcing is important. Due to the speed that the circuit is turned off, current chopping is a factor.
