355-042-555-268

Edgeboard Connectors Overview

The EDAC Inc. 355-042-555-268 is a rotary switch component designed for industrial and commercial applications requiring reliable electrical connectivity. This specific model features a panel mount configuration with a shaft length of 0.42 inches and a total height of 1.25 inches. It utilizes a 5-pole, 5-position design with a non-shorting wiper action to ensure distinct circuit isolation between positions. The switch operates within a temperature range of -55°C to +125°C and supports a maximum voltage of 28V DC. Contact material specifications include gold plating over nickel underplating to maintain low contact resistance and durability against corrosion in harsh environments.

• Military and aerospace instrumentation systems
• Medical device interfaces demanding high reliability

Edgeboard Connectors Procurement Notes

Verify the exact shaft diameter and keyway specifications against your mechanical drawing before ordering. Confirm that the required current rating aligns with your circuit load, as exceeding rated values may compromise contact longevity. Ensure the mounting hole dimensions match the specified panel cutout requirements to guarantee proper fit and sealing. Cross-reference the termination style with your PCB or wire harness layout to avoid assembly issues.

Edgeboard Connectors Selection Notes

Select this model when non-shorting behavior is critical to prevent short circuits during transition between positions. Consider the environmental sealing requirements if the application involves dust or moisture exposure. Evaluate the torque requirements for the operating knob to ensure user-friendly operation without excessive force. Verify compatibility with existing panel thicknesses and mounting hardware constraints.

Edgeboard Connectors Part Context

This part belongs to EDAC's standard rotary switch series, known for robust construction and consistent performance in demanding applications. The numbering convention indicates specific physical and electrical characteristics, including pole count, position count, and shaft dimensions. It serves as a replacement for legacy switches in established designs where form factor and electrical specs must remain unchanged.

Edgeboard Connectors Replacement Considerations

Direct replacements should match the 5-pole, 5-position configuration and identical shaft dimensions. Verify that substitute components offer equivalent contact material and plating thickness to maintain reliability standards. Ensure the new part supports the same voltage and current ratings to prevent operational failures.
