🌡️ Bimetal Snap-Disc Thermostat (2D cross-section)

2D cross-section of a bimetal snap-disc thermostat: a heater warms the disc until it snaps through, opens the contact and cools until it snaps back, giving a hysteresis loop. Same thermal and double-well physics as the 3D page, with fold-point, time-constant and oscillation checks.
