2 AAA battery holders with lids, switches, and wires

Product Name: 2 AAA Battery Holder (with Lid, Switch, and Wires)

Appearance and Structural Features:
Overall Design: This is a compact black rectangular battery holder designed specifically for holding two AAA batteries. Its most notable feature is the slide-out drawer-style design, with the outer shell consisting of a base and a removable slide cover.

Materials and Manufacturing: The outer shell is made of high-quality black engineering plastic (usually ABS), with a matte finish that feels smooth to the touch. It offers good insulation and durability.

Functional Features (Key Points):
Integrated Switch: There's a small toggle switch on the side of the battery holder, clearly labeled with "ON" and "OFF" positions. Users can directly control the power on/off from the battery holder itself, eliminating the need for an additional switch in the external circuit.
Slide-out Cover: The top of the battery compartment features a removable slide cover. This design makes battery replacement very convenient—just pull out the inner compartment like a drawer. When closed, it securely holds the batteries in place, preventing them from falling out due to vibrations and providing dust protection.
Wired Output: Red and black wires are pre-connected at the back of the holder (red for positive, black for negative). This pre-wired design eliminates the need for soldering and is perfect for quick circuit connections.
Mounting Hole: There's a round screw mounting hole on the back of the battery holder, making it easy to attach the holder inside devices or on panels.

Contact System:
Negative Terminal: High-elasticity nickel-plated coil springs are installed at both ends inside the holder, ensuring tight and flexible battery contact.
Positive Terminal: A metal spring contact is located at the other end.

Dimensions:
Length: 64mm
Width: 25mm
Height: 15.8mm

Electrical Specifications: The battery holder features a series circuit design, with two AA batteries providing a continuous output voltage of 3V. It complies with RoHS environmental standards.
