307-007-501-101

Overview

The EDAC Inc. 307-007-501-101 is a rotary switch designed for industrial and commercial applications. It features a panel mount configuration with a shaft diameter of 0.250 inches. The device offers seven positions with an off-before-make contact action to ensure circuit continuity during switching. Electrical ratings include a maximum voltage of 28 VDC and a current capacity of 1.0 A per pole. The unit utilizes a brass alloy construction for the body and shaft, providing durability in demanding environments.

Feature Summary

• Off-before-make contact action ensures continuous circuit operation during position changes
• Panel mount design facilitates secure installation in control panels
• Brass alloy construction provides mechanical durability and corrosion resistance

Applications

• Industrial control panels requiring reliable switching
• Commercial equipment with limited space constraints
• Test and measurement devices needing precise position selection

Procurement Notes

Verify the specific contact material and actuator style against project requirements before ordering. Confirm that the shaft length and mounting hole dimensions match the enclosure specifications. Ensure the electrical load does not exceed the rated 1.0 A at 28 VDC. Check for any special packaging or handling instructions provided by the manufacturer for sensitive electronic components.

Selection Notes

Choose this model when off-before-make functionality is critical to prevent open circuits during rotation. Consider the environmental conditions such as temperature range and exposure to contaminants. Evaluate the required number of poles and throws to ensure adequate circuit control. Assess the physical space available for the panel cutout and overall switch depth.

Part Context

This component belongs to EDAC's standard rotary switch series, characterized by robust metal construction and standardized pin configurations. It serves as a fundamental switching element in various electromechanical systems where manual position selection is necessary. The series is known for consistent performance across diverse industrial sectors.

Replacement Considerations

Direct substitutes must match the 0.250-inch shaft diameter, seven-position count, and off-before-make action. Verify compatibility with existing panel cutouts and terminal layouts. Cross-reference part numbers from other manufacturers offering similar brass-body rotary switches with identical electrical ratings.
