3 AAA battery pack with lid, switch, and wires

Product Name: 3 AAA (7) Battery Holder (with Lid, Switch, and Wires)

Appearance and Structural Features:
Overall Structure: This is a compact black rectangular battery holder designed specifically for holding three AAA (7) batteries. They are arranged side by side, giving it a square shape with rounded corners.
Material and Manufacturing: The outer shell is made of high-quality black PP (polypropylene) resin material with a matte finish. It has good insulation, chemical resistance, and durability. The flame retardant rating is UL94-HB as indicated on the drawing, and the operating temperature range is -10°C to 80°C.

Functional Design (Key Features):
Integrated Toggle Switch: There's a tiny toggle switch integrated on one side of the battery holder (visible as a protrusion from the side view), clearly marked with "ON" and "OFF" positions. Users can directly control the power on and off from the battery holder itself.
Sliding Lid/Clip-on Design: The top of the battery compartment has a detachable or sliding lid secured by clips on the side. The lid has anti-slip patterns for easy opening. Once closed, it effectively holds the batteries in place to prevent them from falling out due to vibration and also serves as a dust shield.
Wired Output: Red and black wires are directly led out from the back (red wire is positive, black wire is negative). The wire specifications indicated on the drawing are UL1007 26# AWG, with a temperature resistance of 80°C. The length is approximately 150±5mm, with 5±1mm of stripped and tinned ends for easy direct soldering or terminal connection. Optional ring terminals (O-type terminals) are also shown in the picture.
Mounting Hole: There's a circular screw mounting hole on the back of the battery holder (hole diameter φ5.20mm) for securely fixing the holder inside equipment or on a panel.

Contact System:
Negative Terminal: One end inside has a highly elastic nickel-plated spiral spring (specification: 0.65mm 65C spring steel wire) to ensure tight battery contact and good adaptability.
Positive Terminal: The other end has a metal spring contact. The rivets are made of nickel-plated brass.

Dimension Specifications (Based on the Drawing):
Total Length: 62mm
Width: 36.3mm
Height: 15.4mm

Electrical Characteristics: It's designed with a series circuit inside, and three AA batteries can provide a DC output voltage of 4.5V. It complies with RoHS environmental standards.
