Abstract

A pressing iron contains a safety turn-off switch to prevent scorching if the iron is held stationary for too long. An acceleration sensor produces a signal in response to a predetermined acceleration of the iron and an actuating circuit turns off the iron if the iron is not sufficiently accelerated.
