Emergency Stop (E-Stop) Switches

EAO Emergency Stop (E-Stop) Switches ensure the safety of operators with consistent, predictable, and controlled responses. These switches are distinguished by their vibrant red actuators, industry-compliant yellow bodies, and fool-proof design for added user protection. These durable and rugged components are suitable for harsh environments and provide immediate and reliable shutdown in critical situations through safe/positive break contacts. The E-Stop switches incorporate innovative designs like mono-block or fail-safe contacts, which enhance end-user safety by rendering the application ineffective. These switches are available with cohesive single units with built-in switch elements or with separate actuators and elements for plug-in, ribbon cable, or PCB terminal connections.
