Equivalent & Substitute Parts for C&K 1201M2S3CLE2 Slide Switch

Part Overview

The C&K 1201M2S3CLE2 is a DPDT (Double Pole Double Throw) slide switch designed for through-hole mounting applications. This component is classified as obsolete and has been superseded by active production alternatives. The 1201M2S3CLE2 operates at 6A (AC/DC) with voltage ratings of 120V AC and 28V DC, making it suitable for general-purpose switching applications requiring reliable contact performance over extended operational cycles.

Due to its obsolete status, sourcing new original inventory of the 1201M2S3CLE2 presents supply chain challenges. Direct substitutes from the same manufacturer series are available and maintain full electrical and mechanical compatibility with the original specification.
