Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 1241.8412 is determined by the following critical parameters:

• Circuit Configuration: SPDT topology is mandatory for functional equivalence
• Current and Voltage Ratings: 100mA DC at 30V minimum specification
• Mounting Configuration: Panel mount, front installation requirement
• Switch Type: Anti-vandal, illuminated construction
• Illumination Specification: Red LED at 24VDC nominal operation
• Termination Interface: Quick Connect 0.110" (2.8mm) connector compatibility
• Panel Cutout Compatibility: 19.10mm circular aperture requirement
• Environmental Compliance: ROHS3 compliance and operating temperature range -25°C to 85°C

The SCHURTER 3-145-524 qualifies as a substitute part based on matching the core functional requirements: SPDT circuit, 100mA at 30V DC rating, pushbutton switch configuration, and active product status with current manufacturing availability.
