208550 - Miller 208550 Replacement Rocker Switch DPST 16A

Technical Overview of the Miller 208550 Rocker Switch

The Miller 208550 is a specialized electromechanical rocker switch designed for use within the control and power circuits of compatible Miller welding power sources. As a Double Pole Single Throw (DPST) switch, it controls two separate circuits simultaneously, making or breaking the connection with a single actuation. This configuration is critical for safety and operational integrity in industrial equipment, often used to isolate both live and neutral lines or to control dual power stages.

Electrically, the component is rated for a substantial load of 16 Amperes at 250 Volts AC. This high rating ensures the switch can handle the inrush currents and sustained loads typical of welding machine operation without contact welding or premature failure. The contacts are engineered to minimize arcing during the switching process, extending the service life of the component even under frequent cycling. The switch features a standard On-Off function, providing clear tactile feedback to the operator regarding the machine's power state.

Physically, the unit is designed for panel mounting, utilizing a snap-in retention mechanism that simplifies installation and replacement. The black actuator housing is constructed from durable, heat-resistant thermoplastics capable of withstanding the thermal and mechanical stresses found in welding environments. When replacing a faulty switch, utilizing this genuine Miller OEM part (SKU 208550) guarantees that the physical dimensions, terminal configurations, and electrical specifications match the original engineering requirements of the machine, ensuring a safe and reliable repair.

Maintenance professionals should verify the fitment of this switch by cross-referencing the machine's serial number or parts manual. While generic switches may appear similar, the specific bezel dimensions and terminal spacing of the Miller 208550 are tailored for seamless integration into Miller equipment enclosures.
