Overview
The Cutler-Hammer 10250T is a proven industrial-grade pushbutton switch series designed for demanding control applications. This lot of three units includes black momentary pushbutton operators paired with compatible contact blocks. Eaton’s 10250T line features 30.5mm diameter pushbuttons with heavy-duty zinc die-cast construction, making them ideal for machine automation, panel-mounted controls, and industrial equipment where durability and reliability are critical.
Key Features
- Heavy-duty zinc die-cast construction with chrome plated housing and mounting nuts for corrosion resistance
- Enclosed silver contacts with reliability nibs that maintain contact integrity even under dry circuit and fine dust conditions
- Drainage holes prevent liquid buildup inside the operator, enabling reliable operation in freezing and wet environments
- Grounding nibs bite through paint and coatings to ensure solid electrical grounding
- Momentary operation with flush button design for standard control applications
- Water-tight and oil-tight sealing suitable for NEMA 3, 3R, 4, 4X, 12, and 13 enclosures

Typical Applications
The 10250T series is widely used in:
- Machine tool control panels and CNC equipment
- Motor starter and VFD control circuits
- Industrial automation and conveyor systems
- Pump and compressor control stations
- Emergency stop and manual override applications
- Manufacturing equipment and production line controls
- HVAC and facility management systems
Compatibility & Replacements
The 10250T pushbutton operator is fully modular and compatible with the complete range of Eaton 10250T Series contact blocks and accessories. Standard contact block options include the 10250T1 (1NO/1NC, 6A, 600V AC) and 10250T2 (2NC configurations). This modular design allows field customization of contact configurations without replacing the entire pushbutton assembly. These units are direct replacements for existing 10250T installations and maintain backward compatibility across the series. Lot quantities (such as this three-unit pack) are ideal for refurbishment, stock replenishment, or multi-position control panel builds.
