4 AA batteries, embedded battery compartment - square, with lid and switch
Product Name: 4 AA (Size 5) Embedded Square Battery Holder (with Lid and Switch)
Appearance and Structural Features:
Overall Structure: This is a compact black square battery holder designed specifically to hold four AA (Size 5) batteries. It features a side-by-side layout, giving it an almost square shape, making it perfect for embedded installation or use as a device back cover.
Material and Manufacturing: The outer shell is made of high-quality engineering plastic (usually ABS) with a matte finish, ensuring durability. The edges have wide mounting flanges, and each corner has a countersunk screw hole for easy and secure attachment to a device panel or casing.
Functional Design (Key Features):
Integrated Toggle Switch: A small toggle switch is integrated on one side edge of the battery holder, clearly labeled with "ON" and "OFF" positions. Users can directly control power on and off from the battery holder itself, eliminating the need for an additional switch in the external circuit.
Flip-Top Protective Cover: The top of the battery compartment has a flip-top lid connected by hinges. The lid has a snap-fit design that secures the batteries in place, preventing them from falling out due to vibration and providing dust protection. The lid also has an arrow indicating the opening direction and the word "OPEN" printed on it.
Mounting Holes: The screw holes at the four corners are perfectly designed to fit into the pre-drilled slots in a device casing, ensuring that the surface of the battery holder is flush with the device's surface.
Contact System:
Negative Terminal: An internally mounted high-elasticity nickel-plated spiral spring ensures tight and flexible battery contact.
Positive Terminal: The other end has a metal spring contact.
