Technical Parameters
The T512A On-On Toggle Switch SPDT (Single Pole Double Throw) is a versatile electrical switch designed for applications requiring a reliable, compact, and durable toggle mechanism. Its On-On configuration allows it to control two circuits, making it a popular choice for various electronic, automotive, and industrial systems.
Key Features
On-On Configuration
Offers two distinct positions: one for each of the two circuits it controls.
Ideal for applications requiring switching between two states or functions.
SPDT Design
Single Pole: Controls a single input circuit.
Double Throw: Connects the input to one of two output terminals, depending on the toggle position.
Compact and Durable Construction
Made from high-quality materials like brass or stainless steel for longevity.
Often features a nickel-plated toggle lever for corrosion resistance.
Ease of Installation
Screw or solder terminals allow for straightforward integration into electrical systems.
Rated for Reliability
Suitable for low- and high-current applications, depending on the specific model.
Often rated for AC and DC use, such as 3A at 250V AC or 6A at 125V AC.
Mechanical Durability
Designed for extended cycles of operation, ensuring consistent performance.
