Door Interlock Handle for Disconnect Switch, Defeatable, Black
The Altech Door Interlock Handle is designed to provide a defeatable control option for disconnect switches, enabling safe service and maintenance procedures. Its robust construction supports reliable operation and quick interlock engagement, helping prevent unintended energy activation. This variant is suited for use where a dark, low-visibility handle is preferred, and integrates with standard disconnect mechanisms commonly found in industrial and HVAC applications.
Key features include straightforward engagement and a compact profile that fits a range of motor disconnect assemblies. While detailed specifications are often determined by the broader switch system, this handle adds a clear physical interlock signal and an accessible manipulation point for technicians performing routine checks or servicing.
Door Interlock Handle for Disconnect Switch, Defeatable, Yellow/Red
Altech’s yellow/red interlock handle provides high-visibility indication for safety-critical shutoff points. The defeatable design enables technicians to temporarily bypass the interlock during controlled maintenance, reducing downtime while preserving the overall safety framework of the disconnect switch system. This option supports quick identification of the interlock status in busy environments and complements standard safety protocols in industrial or HVAC installations.
Durability and compatibility with motor disconnect switches are typical considerations, with the handle forming a robust extension to the interlock assembly. As with other interlock accessories, it is intended to work in tandem with the corresponding disconnect switch hardware to ensure reliable, clear shutoff behavior.
0130M00243 Furnace Interlock Door Switch
This interlock switch is designed for furnace applications, notably compatible with Goodman W/QC models and a range of other brands such as Amana, Carrier, White-Rodgers, Miller, and RUUD RHEEM. It supports a 10A maximum current and 250 VAC maximum voltage, ensuring a strong safety interlock in heating equipment and related systems. The 2-pack option is convenient for replacing worn or failing interlocks across multiple units or zones.
Suitable for attic-mounted air handlers and similar installations, this switch is a practical choice for homeowners or technicians performing repairs or routine maintenance. The versatile compatibility makes it a common substitution for older door switches in compatible furnaces or fireplaces.
KEDU Safety Door Switches with Disconnect

- Compatibility: Verify model numbers and brand compatibility (Goodman, Amana, Carrier, White-Rodgers, RUUD, etc.). Ensure the interlock switch or handle matches your disconnect switch assembly and any door interlock mechanisms present in your equipment.
- Electrical ratings: Check current (A) and voltage (V) ratings. Choose switches rated for at least as much current and voltage as your system to ensure safe operation and avoid nuisance tripping.
- Interlock type: Decide between standard interlock switches and defeatable handles. Defeatable options are useful for controlled maintenance but should be used in accordance with safety protocols to prevent accidental energization.
- Enclosure and protection: Consider IP ratings (e.g., IP54) for environments with dust or moisture exposure. Ensure the enclosure and interlock assembly can withstand installation conditions.
- Durability and materials: Favor switches with robust housings and wear-resistant components to maximize service life in HVAC or industrial settings.
- Ease of replacement: Look for direct replacements (e.g., 0130M00243 or Amana B1370818) to minimize downtime and ensure straightforward installation.
- Color and visibility: High-visibility handles (yellow/red) help technicians quickly identify interlock status in busy facilities, reducing mishandling risk.
- Warranty and support: Check vendor warranties and available replacement parts to support long-term maintenance needs.
