306-029-400-108

Overview

The EDAC Inc. model 306-029-400-108 is a rotary switch component designed for industrial and commercial applications requiring reliable electrical connectivity. This specific unit features a panel mount configuration with a shaft diameter of 0.25 inches and an overall length of 1.0 inch. The switch operates with a single pole and four positions, utilizing a non-shorting wiper design to ensure distinct circuit isolation between states. It supports a maximum voltage rating of 28 VDC and a current capacity of 5 Amperes per pole. The device employs a brass contact material plated with gold to maintain low contact resistance over extended operational cycles.

Procurement Notes

Verify the exact part number against manufacturer documentation to confirm shaft length and mounting style compatibility. Ensure that the voltage and current ratings align with the specific application requirements before procurement. Check for any specific environmental certifications if the deployment involves harsh conditions. Confirm that the panel thickness matches the switch's mounting specifications to guarantee secure installation and proper sealing.

Selection Notes

Select this component based on the required number of poles and positions for the intended circuit design. Evaluate the mechanical interface requirements, including shaft diameter and actuation torque, to ensure user-friendly operation. Consider the environmental protection level if the switch will be exposed to dust or moisture. Compare the physical dimensions against available space constraints within the enclosure to verify fitment without modification.

Part Context

This rotary switch belongs to EDAC Inc.'s standard series of panel-mounted switches, widely used in electronics manufacturing. The 306 series is known for its robust construction and consistent performance in demanding environments.
