Car Yacht RV Battery Switch 50A 100A 200A Plastic Rotary Isolator Cut Off Power Disconnect for Racing Cars Touring Cars Electrical Equipment
Car Yacht RV Battery Switch 50A 100A 200A Plastic Rotary Isolator

This battery switch is a compact plastic isolator designed for cars, yachts, RVs and other vehicle electrical systems. It provides a simple on/off method to disconnect power, which is useful during maintenance, storage or when a vehicle is left unattended. The switch is available in 50A, 100A and 200A versions, so you can choose the rating that matches your circuit. The detachable red knob acts like a key: once removed, the switch cannot be operated, helping to prevent unauthorised use. The body is small, making it easier to fit into tight spaces, and the thick wire screws allow cables to be secured firmly. It is suitable for professional racing cars, touring cars and various electrical equipment in the car, as well as marine and RV applications.
Features and Construction

The switch combines a plastic housing with a red detachable knob and thick wire screws. Its compact form supports installation where space is limited. The available current ratings cover three common options, giving flexibility across different vehicles and equipment.
Material and Build
The main body is made from plastic, which keeps the switch lightweight and provides a non-conductive outer shell. The red knob is detachable and functions as a removable key. Thick wire screws are used for cable connections, allowing wires to be tightened down securely. The source describes the design as sturdy and durable, and the construction is aimed at regular use in automotive, marine and RV electrical systems.
Size and Practical Fit
The switch is described as small in size, which helps when mounting it in confined areas such as engine bays, battery compartments or dashboard panels. No exact dimensions are given in the source information. The compact body and screw terminals make it possible to install in a variety of positions, provided there is enough access to turn the knob and remove it when needed.
Uses and Placement

This isolator switch is intended for vehicles and equipment that require a manual power cut-off. It can be used in racing cars, touring cars, yachts, RVs and other electrical equipment. The detachable knob adds a basic security function, while the on/off action helps with routine maintenance and storage.
Event or Professional Use
In professional racing cars and touring cars, a battery switch may be used to isolate the battery during service or when the vehicle is not in use. The detachable red knob can be removed to prevent others from switching the power back on. The 50A, 100A and 200A options allow teams to select a rating that matches their electrical setup, although the source does not specify exact load requirements.
Everyday Home Use
For caravans, RVs, boats and everyday vehicles, the switch offers a straightforward way to disconnect power from a battery or electrical circuit. It can be fitted to various electrical equipment in the car. The small size and plastic body suit installations where a compact isolator is preferred, and the removable knob provides a simple deterrent against unauthorised use.
Benefits and Buying Value

The switch focuses on practical power control rather than complex features. Its value comes from the detachable knob, the choice of current ratings and the use of thick wire screws. Because it does not rely on a key that stays in the lock, the risk of accidental or unauthorised operation can be reduced when the knob is removed.
Reuse and Low Maintenance
The switch is designed for repeated on/off use. The plastic housing and metal screws can be kept clean with a dry cloth, though the source does not provide specific maintenance instructions. As a mechanical isolator, it has no stated electronic components to configure. The detachable knob can be stored separately when the switch is not in use, helping to prevent unauthorised switching.
Why Choose This Product
Choose this battery switch if you need a compact, plastic isolator with a removable red knob and a choice of 50A, 100A or 200A ratings. It suits racing cars, touring cars, yachts, RVs and other vehicle electrical equipment. The thick wire screws support secure cable attachment, and the small size helps with installation in tight spaces. No additional specifications such as dimensions, wire gauge or waterproof rating are provided in the source text.
