2AA battery holder with knife switch and wire

Product Name: 2AA(5) battery pack with wire

Appearance and Structural Features:
Overall Structure: This is an open black dual-battery holder designed to accommodate two AA (5) batteries. Its most notable feature is a metal toggle switch integrated on the side, providing a very intuitive and secure physical way to disconnect power.
Materials and Manufacturing: The housing is made of black engineering plastic (usually ABS or PBT), which offers good insulation and heat resistance. The bottom is clearly marked with "2AA", "1.5V" and the "RoHS" environmental certification symbol.
Contact System:
Negative Terminal: One end inside features a highly elastic nickel-plated coil spring that can effectively accommodate slight variations in battery size, ensuring stable installation and low contact resistance.
Positive Terminal: The other end has metal prongs or spring contacts (brass-colored contacts visible in the image).
Connection Method: Red and black wires are directly led out from the back (red wire for positive, black wire for negative). This wired design eliminates the need for soldering pins and allows direct connection to circuit boards or other electronic components, making it ideal for DIY projects, repairs, replacements, or scenarios where soldering is inconvenient.
