GLFD01A1B Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The GLFD01A1B is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified within the GLS series. This SPDT (Single Pole Double Throw) switch is designed for chassis mount applications with a side rotary roller actuator, rated for 6A AC at 120V and 550mA DC at 125V. The switch features IP67 ingress protection, making it suitable for dust-tight and waterproof environments.

The GLFD01A1B is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support ongoing maintenance and repair operations for equipment utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLFD01A1B is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Momentary), current ratings (6A AC / 550mA DC), and voltage ratings (120V AC / 125V DC) must be identical.

Mechanical Parameters: Actuator type (side rotary roller), mounting configuration (chassis mount), and termination style (screw terminal) must match exactly.

Environmental Parameters: Ingress protection rating (IP67), operating temperature range (-25°C to 85°C), and mechanical life (15,000,000 cycles) establish the performance envelope.

Compliance Parameters: RoHS compliance status must be maintained.

The GLFC01A1B meets all these criteria and qualifies as a direct substitute for the obsolete GLFD01A1B.
