Overview
The Cutler-Hammer 10250T/91000T heavy-duty pushbutton switch is a proven industrial control component rated for 600V AC or DC operation. This lot includes two units of the standard 30.5mm pushbutton in new condition. The 10250T series represents Eaton’s flagship heavy-duty pushbutton line, engineered for reliability in harsh industrial environments where durability and consistent contact performance are critical.
Key Features

Typical Applications
The 10250T pushbutton series is suitable for a wide range of industrial motor control and machinery applications:
- Start/stop pushbutton stations for electric motors and pumps
- Emergency stop (E-stop) circuits where reliability is paramount
- Industrial machinery control panels and enclosures
- Hazardous duty applications requiring heavy-duty construction
- Outdoor or wet/oily environment installations
- Selector switch and multi-position control circuits
Compatibility & Replacements
The 10250T/91000T is the standard heavy-duty pushbutton series from Cutler-Hammer (Eaton). These switches are direct replacements for existing 10250T installations and are compatible with all standard 30.5mm pushbutton mounting provisions. Common replacement contact block configurations allow field customization for different NO/NC contact needs. For modular pushbutton solutions, Eaton also offers the newer M22 series as an alternative, though the 10250T remains the industrial standard for applications requiring traditional heavy-duty construction and proven long-term field performance.
