200A/M10 Battery Switch
A 200A/M10 battery switch is a robust, high-current manual switch designed to make or break the electrical circuit between a battery (or battery bank) and a vehicle's or system's electrical load.
The key specifications in the name define its performance and physical characteristics:
200A (Amperes): This refers to the switch's continuous current rating, meaning it can safely handle a constant flow of 200 amps of electrical current without overheating or failure. It typically has a much higher intermittent or cranking capacity (e.g., 1000A for 10 seconds) for starting engines.
M10: This denotes the size and type of the connection studs (bolts/terminals). M10 refers to a metric 10mm diameter stud, which is typically made of tinned copper or brass to ensure reliable and corrosion-resistant electrical conductivity for the high-current cables.
Purpose and Applications
The primary function of this type of switch is safety and maintenance.
It is widely used in:
-
Marine vessels (boats, yachts)
-
Recreational vehicles (RVs, campers, caravans)
-
Dual battery setups to manage power distribution between multiple batteries
By physically separating the battery from the rest of the system, a 200A/M10 battery switch provides several benefits
