Switches
In the professional truck and trailer industry, a reliable switch is far more than a simple operating element. Every electrical installation in a heavy goods vehicle, semi-trailer or drawbar trailer depends on the quality of the switches integrated into it. From the main switch truck 24V that controls the entire battery current to the smallest pushbutton switch for an auxiliary function on a bodywork: each switch type has a specific role and must meet the demands of the heavy transport environment. Dekoff.com offers a wide and purpose-built range of switches for 12V and 24V systems, compiled for workshop professionals, trailer builders, bodybuilders and coachbuilders who work daily with complex vehicle electronics.
The switches category covers several subcategories, each focused on a specific application or operating method. Together they form the complete spectrum of switching solutions required in truck and trailer construction.
Main switches form the core of every professional electrical installation. A power switch HGV or a 24V main switch with high switching capacity makes it possible to interrupt the complete circuit safely and directly. This is essential during maintenance, storage and situations where current leakage must be prevented. Within this segment, switches are available for a wide range of current ratings, from compact versions for lighter installations to heavy-duty main switches with peak switching capacities of several thousand amperes for large 24V applications in trucks, buses and construction machines. Some versions feature IP65 protection, making them resistant to dust and water jets and therefore suitable for installation in locations exposed to the elements. M8 or M10 bolt connections ensure a solid, low-resistance connection with the battery cables. Key-operated versions add an access control element, preventing unauthorised operation — a requirement in professional and industrial environments.
Pull switches are a trusted choice in truck workshops and trailer construction. Operation via a pulling motion is intuitive and the switch position remains visibly held, making this type suitable for functions where it must be immediately clear whether a circuit is active. Pull switches for 24V systems are used for auxiliary functions on bodywork, lighting, hydraulic systems and other installations requiring a stable on/off state. They are available as individual items or in larger quantities for workshops and wholesalers seeking efficient purchasing.
Pushbutton switches are used where a temporary or permanent switching action with a simple pressing motion is required. In the truck and trailer sector they are used for start functions, signal generators, emergency functions and various auxiliary switches on bodies and trailers. Splash-proof versions are suitable for outdoor use or installation in splash-prone zones. Depending on the version, they are suitable for 12V or 24V systems, with corresponding maximum current ratings. Replacement membrane parts for pushbutton switches ensure that the seal between the switch button and the housing remains intact, which is critical for the durability and splash-proof performance of the installation.
One application that deserves particular attention in the trailer and truck sector is the emergency stop switch trailer. This type of switch enables an immediate and complete interruption of the power supply in emergency situations, minimising the risk of fire, electrical damage or hazardous conditions during storage or maintenance. Emergency stop switches must meet strict safety requirements and are therefore designed for use in environments where reliability and rapid response are paramount.
Across the entire switches range, suitability for 12V and 24V systems, robustness and durability in demanding environments are the leading criteria. Workshops and trailer builders looking for a main switch truck 24V, a splash-proof pushbutton switch or replacement switch parts will find a clear and professionally composed range at Dekoff.com that connects directly to the daily practice of the heavy transport sector.
