Overview
The Blue Sea Systems 4141 is a switch meter toggle with SPTT ON-ON-ON action for selecting between battery banks when checking voltage with a digital or analog voltmeter or multimeter. It gives you three selectable positions at the panel, so one meter can be used to read different banks without moving test leads.
This layout works well on boats with separate start, house, and auxiliary batteries that need a clean way to compare bank voltage from one monitoring point. The switch includes a three-position battery bank label, and the unit weighs 0.02 lb (0.01 kg).
Key features
- SPTT ON-ON-ON switch action for three-position battery bank selection on a meter circuit
- Works with digital and analog voltmeters or multimeters
- Lets one meter read multiple battery banks from the same panel location
- Includes a three-position battery bank label for clear bank identification
- Low 0.02 lb (0.01 kg) weight for compact monitoring layouts
Compatibility and use on board
This switch is meant for battery monitoring circuits where one meter is shared across more than one bank. That makes it a practical fit for older helm panels with analog meters and for newer custom panels built around digital voltage checks.
It is a good match for boats that want quick battery status checks before departure, while charging, or when managing separate banks at anchor. Placing it next to the meter keeps bank selection and voltage reading in one spot, which makes routine checks faster and easier to follow.
