Product Name: 2 AA (7) Open Battery Holder with Slide Switch/Wired Output
Appearance and Structural Features:
Overall Design: This is a minimalist black open battery holder designed specifically for two AA (7) batteries. It doesn't have a fully enclosed shell but instead features a skeleton-like structure, allowing you to see the inside of the battery compartment clearly.
Materials and Manufacturing: The main body is made of black engineering plastic (usually ABS or PBT) with a smooth surface. The inside is clearly marked with "1.5V", "AAAX2", and positive/negative polarity indicators for easy battery installation.
Functional Features (Key Points):
Metal Slide Switch: The most prominent feature is a long rectangular metal slide switch on the side. It's a purely mechanical on/off mechanism that you can manually toggle to connect or disconnect the circuit. This design is simple, durable, and cost-effective.
Wired Output: Red and black wires are directly led out from the back (red for positive, black for negative). This pre-wired design eliminates the need for soldering and is perfect for quick circuit connections.
Contact System:
Negative Terminal: Both ends inside are equipped with highly elastic nickel-plated coil springs that can effectively accommodate slight variations in battery size, ensuring good contact.
Positive Terminal: The other end has a metal tab or spring contact.
Dimension Specifications (Based on Image Labels):
Total Length: 51mm
Width: 24mm
Height: 12mm
Mounting Hole Diameter: 3.7mm (marked circle diameter in the image)
Electrical Characteristics: It's a series circuit design inside, and two AA batteries can provide a DC output voltage of 3V.
