Product Name: 2 AA Battery Holder (with Lid, Switch, and Wires)
Appearance and Structural Features:
Overall Design: This is a compact black rectangular battery holder designed specifically for two AA batteries. It has a square shape with rounded corners and features a modular design.
Materials and Manufacturing: The outer shell is made of high-quality black engineering plastic (usually ABS) with a matte finish, providing good insulation and durability.
Functional Features (Key Points):
Integrated Switch: A small toggle switch is built into one end of the battery holder, clearly labeled with "ON" and "OFF" positions. Users can control the power on/off directly on the holder, eliminating the need for an additional switch in the external circuit.
Sliding Lid Design: There's a pull-out sliding lid on top of the battery compartment. The lid is secured with a snap, making it easy to open and closing it effectively to keep the batteries in place and protected from vibration, while also serving as a dust cover.
Wired Output: Red and black wires are directly connected at the back (red for positive, black for negative). This wired design eliminates the need for soldering pins and can be easily connected to circuit boards or other electronic components, making it perfect for DIY projects or repairs.
Contact System:
Negative Terminal: High-elasticity nickel-plated coil springs are installed at both ends inside to ensure tight and flexible battery contact.
Positive Terminal: A metal spring contact is located at the other end.
