Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 1241.6634.1122000 is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain SPDT to maintain electrical functionality in applications requiring changeover switching. Current and voltage ratings (5A at 125V AC) are non-negotiable for safe operation within specified load conditions. The switch function (On-Momentary) defines the operational behavior required by the application. Mounting type (panel mount, front) and panel cutout dimensions (22.10mm circular) ensure mechanical compatibility with existing enclosure designs. Anti-vandal and illuminated characteristics are functional requirements that must be preserved. Termination style (quick connect 0.110") must match to ensure proper connection without adapter requirements. Operating temperature range, mechanical life, and electrical life specifications establish the performance envelope for the application environment.

The SCHURTER 3-145-553 qualifies as a manufacturer-recommended substitute based on matching SPDT circuit configuration, 5A at 125V AC electrical ratings, and pushbutton switch functionality. This part is currently in active production status, providing supply continuity for the obsolete 1241.6634.1122000.
