Testing Process of Epoxy Sealed Thermal Switches – DC Rating

To ensure the highest quality and reliability of our products, one of our skilled engineers conducted extensive DC cycle testing on our 2570 sealed thermal switch. The ongoing cycle testing has seen the switch endure an impressive 139,000 cycles and continue to operate flawlessly. The specific switch under scrutiny is the 2570L334-227, tested at 13VDC and 12.2 amps. It’s essential to note that this particular model is from our 2570 family, and we anticipate similar performance from any switch within our 2570 and 431 families.

Epoxy Sealed Thermal Switch Specifications

Our epoxy sealed thermal switches have been proven to function reliably in DC voltage applications. These switches are UL rated for 100,000 cycles at 15 Amps for 120VAC, 10 Amps for 240VAC, and 0.5 Amps for 24VDC. This demonstrates their versatility and ability to meet the demands of various electrical systems.
