Honeywell 1CPSA4B Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Honeywell 1CPSA4B is a snap action switch featuring 4PST-NC (four pole, single throw, normally closed) configuration with a 10A current rating at 600V AC and 250V DC. This switch includes a lighted indicator and meets IP67 ingress protection standards for dust-tight and waterproof operation across an operating temperature range of -40°C to 80°C.

The 1CPSA4B is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing maintenance and production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1CPSA4B is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: 4PST-NC
• Current rating: 10A (AC/DC)
• Voltage rating: 600V AC / 250V DC
• Ingress protection: IP67
• Operating temperature range: -40°C to 80°C
• RoHS compliance status
• Manufacturer: Honeywell Sensing and Productivity Solutions
• Series: CPS

The 1CPSC4 meets all mandatory electrical and mechanical parameters required for direct substitution. The primary distinction is product status: the 1CPSA4B is obsolete, while the 1CPSC4 maintains active production status within the same CPS series.

Parameter Comparison
