2AAA rechargeable square battery pack with lid and switch, black
Product Name: 2 AAA Battery Holder with Cover and Switch, Black
Appearance and Structural Features:
Overall Design: This is a compact black rectangular battery holder designed specifically for two AAAbatteries. It's flat in shape, making it ideal for recessed installation or use as a battery compartment on the back of devices.
Material and Manufacturing: The casing is made of black engineering plastic (usually ABS) with a matte finish, providing good insulation and durability.
Functional Features (Key Points):
Flip-Top Design: The top of the battery compartment features a flip-top lid connected by a hinge. The lid is marked with "OPEN" and an arrow indicating the opening direction for easy identification. Once closed, the lid is secured with a snap, effectively preventing accidental battery dislodgement.
Integrated Switch: A miniature toggle switch is integrated at one end of the battery holder (on the bottom edge), allowing users to directly control the power on/off without having to open the lid or disconnect the connection.
Mounting Holes: There are round screw mounting holes at each of the four corners of the battery holder base. This four-corner mounting design is perfect for securely embedding the holder into a device panel or fixing it on a flat surface.
Contact System:
Negative Terminal: One end inside features a highly elastic nickel-plated coil spring to ensure tight and flexible battery contact.
Positive Terminal: The other end has a metal spring contact.
Connection Method: The bottom has two metal spring pins (SMT/through-hole compatible) for easy direct wiring or plugging into a circuit board socket.
