A resettable fuse (500 mA) is available for external micro-USB power supply.

Provided is a technique for changing the action sensitivity of a self-restoring fuse to a mechanical input, without changing the constitution and specifications of the fuse element body.

A mechanical fuse for cutting the power current in response to mechanical shocks or vibrations is equipped with the self-restoring fuse for performing a breaking action in response to an excess current.

It took us a long time and hundreds of experiments to finally be able to customize the perfect auto-resetting fuse at the right cost and size for our product.

This self-restoring fuse is constituted such that solid conductive particles are diffused to flow in a liquid matrix filling an insulated container, and such that electrodes are arranged to confront each other.

A trip coil (22) is excited by a charge stored in a trip capacitor (21) serving as a trip power supply, while a reset coil (32) is excited by a charge stored in a reset capacitor (31) serving as a reset power supply.

The fuse puller has a fuse gripping portion for gripping a fuse.

A fuse device comprises a fuse carrier (2) for carrying a fuse (8) and a fuse base.

The fusible path (PF) includes an electromigratable fuse (F1) and a 'fusible-path' transistor (QF) in series with the fuse.

A gear-driven clutching and resetting device of a door lock comprises a clutch (1), a rotary ring (2), a reset block A (3), a reset spring (4), a reset block B (5) and a locating pin (6).
