4 AA battery pack with lid and switch, comes with RoHS and CE certifications

Product Name: 4 AA (Size 5) Enclosed Battery Holder (with Lid, Switch, and Wires)

Appearance and Structural Features:
Overall Structure: This is a fully enclosed black square battery holder designed specifically for holding four AA (Size 5) batteries. Unlike previous open-frame designs, it has complete upper and lower casings that effectively protect the internal circuit and batteries.

Materials and Manufacturing:
Casing: The main body is made of black PP (polypropylene) resin with a matte finish, providing good insulation and impact resistance.
Contacts: Internally, there are high-elasticity nickel-plated coil springs (negative) and metal tabs (positive) to ensure secure battery contact.

Functional Design (Key Features):
Sliding Lid: The lid opens by sliding and is marked with the word "OPEN" and an arrow for easy reference. This design allows users to quickly replace batteries while keeping them dust- and drop-proof when closed.
Integrated Switch: A miniature toggle switch is integrated on the side of the battery holder, clearly labeled with "ON" and "OFF" positions. Users can control power on/off directly on the battery holder itself, eliminating the need for an additional switch in the external circuit.
Wired Output: A set of red and black wires (red positive, black negative) are led out from the side. According to the diagram, the wire specification is UL1007 26#, with a length of about 150mm. The ends are stripped and tinned for easy soldering.
Mounting Hole: There is a circular screw mounting hole on the surface of the box for easy installation inside equipment or on a panel.

Dimension Specifications (Based on Diagram):
Length: Approximately 69.7mm
Width: Approximately 64.4mm
Height: Approximately 19.5mm
This is a very compact square design, with a thickness of less than 2cm.

Electrical Characteristics: The internal circuit is designed as a series connection, and four AA batteries can provide a DC output voltage of 6V.
