Push Button Switches
Audio Plugs & Jacks

NEXUS Incorporated was founded in 1961 by Randolph K. Byers and William H. Flanagan to perfect the design and manufacture of superior quality audio plugs, jacks and MIL-S-8805/3 push-button switches. Since 1961, NEXUS connectors have become the standard in military and commercial communication headset markets.

Today, NEXUS connectors are typically specified in OEM headset applications where "breakaway-style" audio connectors are required. NEXUS switches have a very strong, 'tactile-feedback' feature that makes them ideal for applications that require a positive means of knowing that the switch has actuated. In addition, NEXUS switches are designed for applications that require a durable, reliable and cost effective switching means. Other applications of NEXUS audio connectors and pushbutton switches are in Auto Racing, Powerboat Racing, Telecommunications, Simulation Controls, Medical Products, Farm Equipment, and Commercial Aviation Electronics.
