12V 24V Dual Voltage Battery Master Cut Off Switch Zinc Alloy Structure Negative Pole Disconnect Tool Free Knob PCB Design
Price range: $11.70 through $19.95
Description
Description:
Zinc alloy structure, efficient conduction: The switch is forged from high-purity aluminum to ensure low resistance and minimal power loss. The metal housing effectively dissipates heat to ensure long-term stable operation.
12/24V dual voltage compatible: Suitable for 12V and 24V battery systems, suitable for cars, trucks, RVs, ships, etc., it can cut off the negative power supply to prevent the battery from idling and consuming power.
Negative pole cut-off function, safe and convenient: Compared with the positive pole cut-off, the negative pole circuit disconnection function reduces the risk of short circuit and is safer to operate. The manual knob enables tool-free switching.
Compact PCB design, saving installation space: The small shape fits in small spaces (battery compartment, trunk). Standard terminals support series/parallel wiring for flexible installation.
Professional battery management, extending battery life: Completely cut off the parasitic power consumption of standby electronic devices (clocks, alarms), minimizing battery loss-ideal for the maintenance of long-term storage vehicles.

Nice will see how well it works.

The main battery switch consists of aluminum alloy contacts (al) and a copper jumper (cu). The copper jumper is moved with the help of a handle to and from the aluminum contacts, closing or opening the circuit. Looks suitable for use in a private vehicle. The weak point is the metal pair cu-al, which can corrode over time. Due to the low price, the switch can be replaced from time to time just in case.
Fast delivery. Thanks for service, seller.

Faster shipping and delivery. Came as described and hopefully works as described. One box also came with 2 pieces of metal. I’m not sure what it is or what’s it used for in relation to the unit. I may update after testing.
