Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1241.6663.1122000 is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current and voltage ratings (5A at 125V AC)
• Switch function (On-Momentary)
• Mounting configuration (Panel Mount, Front)
• Anti-vandal and illuminated design characteristics
• Termination style (Quick Connect - 0.110")
• Panel cutout dimensions (Circular - 30.10mm)

The SCHURTER 3-145-648 qualifies as a substitute based on matching the core electrical specifications (SPDT, 5A, 125V AC) and functional classification as a pushbutton switch. This part is currently in active production status, providing continuity for applications requiring the same electrical and mechanical interface.

Parameter Comparison

Engineering Selection Recommendations
