CR2032 button cell holder with wire, lid, and switch for tram batteries

Product Name: CR2032 Button Battery Holder (with Cover, Switch, and Wires)

Appearance and Structural Features:
Overall Design: This is an ultra-small, black (also available in transparent) oval battery holder designed specifically to hold one CR2032 button lithium battery. It has a sleek, capsule-like shape, making it perfect for microelectronic devices with extremely tight space requirements.

Materials and Manufacturing:
Shell: The main body is made of engineering plastic (ABS or PC), with a matte finish for the black version and a semi-transparent finish for the transparent version. The transparent version allows direct observation of the battery status inside.
Contacts: Gold-plated or nickel-plated metal spring contacts are used on the inside for positive and negative connections, ensuring good electrical conductivity with the button battery.

Functional Features (Key Highlights):
Integrated Toggle Switch: A tiny 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.
Snap-on Protective Cover: The top of the battery compartment features a removable cover secured by small snaps on the side. The compact design effectively holds the battery in place, preventing it from falling out due to vibrations, and also provides dust protection.
Wired Output: Fine red and black (or transparent insulated) wires are directly led out from the back. This pre-wired design eliminates the need for soldering steps, making it ideal for quick connections to microcircuits.

Dimension Specifications (Based on Image Labels):
Length: 52.2mm
Width: 23.8mm
Height: 5.9mm

This is a very flat design with a thickness of just 5.9mm, making it easy to conceal and install.

Electrical Characteristics: A single CR2032 battery can provide a DC output voltage of 3V.
