CASE STUDIES
Legacy 12V lighting control in RVs and marine vehicles often relied on basic mechanical switches, resulting in harsh lighting transitions, limited control, and poor aesthetics. OEMs were seeking a sleek, serviceable, and modern solution that could integrate smoothly into existing 12V systems — without the complexity of networked controllers or proprietary buses. User expectations around dimming, memory, and device modularity were rising, and the market lacked a flexible, full-featured alternative designed specifically for RV applications.
Steiner developed a fully integrated family of 12VDC wall-mounted wired devices, centered around a patent-pending digital dimmer switch with smooth PWM-based control. Designed from the ground up — including PCB layout, firmware, mechanical housing, and packaging — the system allows snap-in installation with a clean, modular aesthetic. The result is a next-generation control interface that feels refined, behaves intelligently, and installs with ease.
The family includes:
Digital Dimmer Switch
Digital On/Off Switch
Occupancy Sensor Switch
Night/Step Light
USB-A + USB-C Charging Module
Advanced pulse-width modulation enables ultra-smooth, linear brightness ramping across a wide range of 12VDC lighting loads
User-selected brightness settings are stored and persist even after full power loss
Slow-on and slow-off transitions prevent visual shock and create a premium, ambient experience
Built-in current detection and automatic shutoff protect against overload and fault conditions
Devices snap into single or dual-gang brackets with a patented enclosure design that allows quick field service — similar to a TV remote battery door
Optimized for volume production, consistent installation, and aesthetic integration into modern coach interiors
And cost-optimized manufacturing
This dimmer system is actively shipping to multiple RV OEMs and marine manufacturers. Its modular platform simplifies design cycles and offers customers a refined user experience while reducing wiring errors and install times. With new smart variants and accessories in development, the product line is positioned to become a foundational standard for 12V control in mobile environments.
