The EH-UM9V/B is a professional-grade battery management solution designed to house a standard 9V (PP3) battery within a secure, fully enclosed protective casing. Unlike standard open-frame holders, this model features an integrated manual power switch and a sliding cover, making it an ideal choice for portable devices and field equipment where safety and energy conservation are priorities.
Built-in ON/OFF Slide Switch: Features a dedicated toggle switch located on the side of the housing, allowing you to cut power to your circuit without removing the battery or disconnecting wires.
Fully Enclosed Protection: The robust ABS plastic box includes a snap-fit sliding cover that completely encapsulates the battery, protecting it from dust, moisture, and accidental short circuits.
Secure 9V Snap Terminals: Internal high-tension snap connectors provide a reliable electrical link, ensuring the battery remains connected even under heavy vibration or impact.
Color-Coded Lead Wires: Equipped with standard red (positive) and black (negative) insulated output wires, pre-stripped for quick integration into your project.
Low-Profile Compact Design: The slim rectangular form factor is designed to fit easily into handheld project enclosures and industrial control panels.
Model Number: EH-UM9V/B.
Battery Capacity: 1x 9V (PP3 / 6LR61).
Switch Type: SPST Slide Switch (Manual).
Housing Material: Impact-Resistant Black ABS.
Termination: Insulated wire leads.
Portable Testing Tools: Provides switchable power for handheld signal generators, multimeters, and environmental sensors.
Guitar & Audio Gear: Excellent for powering active preamps or effects pedals where an external, switchable battery compartment is needed.
DIY Prototypes: A favorite for Arduino and ESP32 projects that require a 9V source with a built-in power management toggle.
Educational Kits: Safer for student use in science projects due to its fully enclosed design and manual kill-switch.
Does the switch disconnect both wires? The integrated slide switch is an SPST (Single Pole Single Throw) type that breaks the positive (red) circuit, effectively stopping all power flow to your device when set to "OFF".
Is the battery difficult to change? Not at all. The cover features a thumb-grip for easy sliding. Once open, the 9V battery can be swapped in seconds thanks to the standard snap terminals.
Can I mount this to a flat surface? Yes, the flat bottom of the ABS box is suitable for mounting with heavy-duty double-sided tape or by drilling small pilot holes through the base (avoiding the internal terminals).
