How the Infinite Switch Works

An infinite switch is a bimetal heat regulator. As current flows to the surface element, a small bimetal strip warms up, trips contacts open, then cools and closes them again — cycling 240V power in precisely timed intervals. Failure modes: pitted contacts stick fully on, weakened bimetal won't trip, spring tension changes make the knob feel loose, degraded contacts produce inconsistent heat.
