Snap Disc Controls
Reliable, Snap-Action Temperature Control for Equipment Protection
Snap Disc Controls provide dependable, repeatable temperature control using a proven bi-metal snap-action mechanism. Designed for applications requiring precise actuation at defined temperature thresholds, these compact mechanical devices deliver consistent performance across a wide range of equipment and systems.
As part of the Fenwal Controls portfolio within the KiddeFenwal family of brands, Snap Disc Controls are engineered for durability, simplicity, and long-term reliability in industrial and commercial environments.
The Snap Disc Advantage
Fast, Repeatable Actuation at Critical Temperatures
Snap Disc Controls operate using a bi-metal disc that responds to temperature changes by “snapping” at a calibrated set point. This rapid, decisive action ensures reliable opening or closing of electrical contacts, helping protect equipment and maintain safe operating conditions.
This snap-action response minimizes contact wear and ensures consistent performance over time, making these devices ideal for applications requiring dependable temperature limiting or control.
