EAO Ltd

EAO is a Swiss, family-owned company and global expert in human-machine interfaces (HMI), delivering high-quality pushbuttons, keypads and control systems for reliable, intuitive operation in demanding environments.

EAO provides advanced HMI solutions for heavy-duty and off-highway vehicles, with a focus on Series 09 CANbus keypads and rotary cursor controllers (RCCs) designed for heavy-duty applications.

Developed for construction, agricultural and specialist vehicles, Series 09 offers outstanding durability and long service life in harsh conditions. The range includes 2, 6 and 8-way CANbus keypads alongside a rotary controller combining joystick and encoder functionality with integrated pushbuttons for precise control. IP69K-sealed versions ensure reliable outdoor use, while compact in-cabin variants suit space-restricted dashboards. With CANopen Safety and Performance Level d (PLd), Series 09 supports safety-critical functions.

Complementing this, Series 46 provides a modular, cost-effective range of pushbuttons, selector switches and emergency stop switches. Available in 22 mm and 30 mm formats, Series 46 is easy to configure and offers sealing up to IP69K on some actuator styles.

Together, these ranges deliver flexible, robust HMI solutions for heavy-duty and industrial applications.
