Bulgin SX0792/63 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The Bulgin SX0792/63 is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 10A at 250V AC and 28V DC. It features a momentary-off-momentary (Mom-Off-Mom) switch function with panel mount installation and non-illuminated standard round actuator. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bulgin SX0792/63 is determined by the following critical parameters:

Circuit Configuration: SPDT topology must be maintained for functional equivalence.

Switch Function: Mom-Off-Mom operation is required for identical behavioral characteristics.

Mounting Type: Panel mount configuration must be preserved for mechanical compatibility.

Termination Style: Quick Connect - 0.250" (6.3mm) terminals ensure direct connection compatibility.

Actuator Type: Standard round actuator maintains physical interface consistency.

Current and Voltage Ratings: Substitute parts must meet or exceed the original 10A (AC/DC) and 250V AC / 28V DC ratings to ensure safe operation in the intended application.

Panel Cutout Dimensions: Circular 12.00mm diameter cutout compatibility is essential for panel integration.

The CW Industries GTS447G101HR satisfies all substitution criteria within the allowed parameter tolerance.

Parameter Comparison

Engineering Selection Recommendations

The CW Industries GTS447G101HR is a qualified substitute for the obsolete Bulgin SX0792/63 based on the following factors:

Functional Equivalence: Both components share identical SPDT circuit configuration and Mom-Off-Mom switch function, ensuring direct functional replacement.

Electrical Compatibility: The GTS447G101HR exceeds the original current rating (16A vs. 10A) and AC voltage rating (277V vs. 250V), providing enhanced electrical capacity for the application.

Mechanical Compatibility: Panel mount configuration, standard round actuator, and Quick Connect 0.250" (6.3mm) termination are preserved. Panel cutout dimensions are compatible (12.20mm vs. 12.00mm).

Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

Product Availability: The GTS447G101HR is active in production with substantial inventory availability, ensuring long-term supply continuity.

Enhanced Features: The substitute provides IP56 ingress protection and documented 10,000-cycle electrical life, offering improved environmental resilience compared to the original component.

Frequently Asked Questions (FAQ)

Q: Can the CW Industries GTS447G101HR directly replace the Bulgin SX0792/63 in existing applications?

A: Yes. Both components share identical SPDT circuit topology, Mom-Off-Mom function, panel mount configuration, and Quick Connect 0.250" (6.3mm) termination. Panel cutout dimensions are compatible within standard manufacturing tolerances (12.00mm vs. 12.20mm).

Q: What are the key differences between these components?

A: The GTS447G101HR provides higher current capacity (16A vs. 10A AC), higher AC voltage rating (277V vs. 250V), shorter actuator length (17.50mm vs. 20.20mm), IP56 ingress protection, and documented electrical life (10,000 cycles). The original component operates at lower temperature minimum (-20°C vs. 0°C).

Q: Are there any compatibility concerns with the actuator length difference?

A: The GTS447G101HR actuator is 2.70mm shorter (17.50mm vs. 20.20mm). This difference must be evaluated against the specific panel thickness and user interface requirements of the application. Mechanical fit verification is necessary before implementation.

Q: Does the GTS447G101HR support DC voltage operation?

A: The GTS447G101HR specification does not explicitly state DC voltage rating. The original SX0792/63 is rated for 28V DC. DC operation compatibility must be confirmed with the manufacturer before substitution in DC-only applications.

Q: What is the significance of the IP56 rating on the substitute part?

A: IP56 classification indicates dust protection and water resistance. This enhancement provides superior environmental protection compared to the original component, which has no specified ingress protection rating. This is beneficial for applications in harsh or wet environments.

Q: Are both components RoHS compliant?

A: Yes. Both the Bulgin SX0792/63 and CW Industries GTS447G101HR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
