A transverse connector lets both terminals exit at the same height, simplifying sealing and reducing stress on the temperature-dependent switching element.
A captive bimetal and spring snap-disc assembly protects fragile parts in storage and enables simpler switch assembly with pre-installation testing.
An integrated bimetallic fuse and thermal disconnector lets an SPD carry surge currents yet open short circuits without large external fuses.
Segmented phase-change regions, insulated thermal pillars, and local heaters speed switching while reducing leakage currents and energy use.
Segmented phase-change regions, thermal pillars, and isolated heaters speed RF switching while reducing leakage and power use.
A shape-memory alloy lock keeps a thermal switch open after overheating, preventing shock- or temperature-driven reclosure after cooling.
