Overview
The ALCO TT-13 is a sub-miniature toggle switch manufactured by ALCOSWITCH, a TE Connectivity brand, designed for demanding industrial and commercial applications. This SPDT (Single Pole Double Throw) on-off-on configuration provides reliable switching performance with a compact footprint suitable for panel-mount installations where space is critical.
Key Features
- SPDT on-off-on circuit configuration for versatile control logic
- Rated 3A at 125VAC or 1.5A at 250VAC for AC applications
- Sub-miniature design saves panel space in tight control enclosures
- Solder lug terminals for secure, permanent electrical connections
- High-temperature polyester frame for durability in industrial environments
- Wide voltage compatibility (125VAC/250VAC operation)

Compatibility & Replacements
The ALCO TT-13 is the TE Connectivity version of classic ALCOSWITCH toggle switch designs used in industrial electronics for decades. When sourcing replacements or alternatives, verify the exact circuit configuration (SPDT, DPDT, etc.) and voltage/current ratings required by your application. The sub-miniature form factor is standard across most ALCOSWITCH TT-series models, ensuring panel hole compatibility (0.25″ bushing diameter is typical for this series). Consult the original equipment manufacturer’s specifications or contact our technical support team to confirm interchangeability with existing installations.
