An inhalation system for generating a vapour for inhalation by a user includes an inhalation device including a controller and a vapour generating article including a vapour generating material and a heating element. The controller is configured to provide a power supply profile adapted for a single use of the vapour generating article and having at least two sections with differing values of intensity per unit time of power supplied to the heating element. During a first section, the intensity per unit time of power supplied to the heating element has a first value arranged to maintain a target temperature at which a vapour is generated due to heating of the vapour generating material. During a second section, the intensity per unit time of power supplied to the heating element has a second value which is higher than the first value. The heating element is arranged to be broken to thereby break its electrical path when the second value of intensity per unit time of power has been supplied to the heating element a predetermined number of times.

A circuit interrupter includes a fixed terminal, a movable contactor, a moving mechanism, a squib, and accommodation. The fixed terminal includes a fixed contact. The movable contactor includes a movable contact connected to the fixed contact. The moving mechanism is configured to move the movable contactor from a closed position where the movable contact is connected to the fixed contact to an open position where the movable contact is separated from the fixed contact. The squib is configured to generate gas by combustion. The accommodation is for accommodating the fixed contact and the movable contactor. In the circuit interrupter, the gas is introduced into the accommodation.

A temperature-dependent switch having a housing with an upper part and a lower part, wherein a first and a second stationary contact are arranged on the housing, and a temperature-dependent switching mechanism having a movable contact member. In its first switching position, the switching mechanism presses the movable contact member against the first contact and thereby produces an electrically conductive connection between the two contacts via the contact member, and, in its second switching position, keeps the movable contact member spaced apart from the first contact. A closing lock prevents the switch, once having opened, from closing again by locking the switching mechanism permanently in its second switching position in a mechanical manner. The closing lock comprises a substantially disc-shaped locking element and a first latching member, which, in order to lock the switching mechanism, interacts in the second switching position with a second latching member that is arranged on the movable contact member.

A temperature-dependent switch comprises first and second stationary contacts and a temperature-dependent switching mechanism having a movable contact member and a temperature-dependent snap-action part, which transitions between geometric low- and high-temperature configurations based on a temperature of the switch. Switching the snap-action part from its geometric low- to high-temperature configuration moves the switching mechanism from a first to a second switching position and thereby opens the switch. A closing lock prevents the switch once having opened from closing again by keeping it in its second switching position. The closing lock comprises a fusible medium which melts when a melting temperature of the medium is exceeded, contacts, in a molten state, a part of the switching mechanism when it is in its second switching position, and solidifies again and thereby locks it in its second switching position when the temperature of the switch falls below the melting temperature of the medium again.

A temperature-dependent switch has a first and a second stationary counter contact and a temperature-dependent switching mechanism with a contact member. The switching mechanism, in its first switching position, presses the contact member against the first counter contact and, in this case, produces an electrically conducting connection between the two counter contacts via the contact member. The switching mechanism, in its second switching position, holds the contact member at a spacing from the first counter contact. A closing lock is provided, which prevents the switch, once opened, from closing again. The closing lock locks the temperature-dependent switching mechanism permanently in the second switching position thereof in a mechanical manner.

A surge protective device (SPD) module includes a module housing, first and second module electrical terminals mounted on the module housing, a gas discharge tube (GDT) mounted in the module housing, and a fail-safe mechanism mounted in the module housing. The GDT includes a first GDT terminal electrically connected to the first module electrical terminal and a second GDT terminal electrically connected to the second module electrical terminal. The fail-safe mechanism includes: an electrically conductive shorting bar positioned in a ready position and repositionable to a shorting position; a biasing member applying a biasing load to the shorting bar to direct the shorting bar from the ready position to the shorting position; and a meltable member. The meltable member maintains the shorting bar in the ready position and melts in response to a prescribed temperature to permit the shorting bar to transition from the ready position to the shorting position under the biasing load of the biasing member. In the shorting position, the shorting bar forms an electrical short circuit between the first and second GDT terminals to bypass the GDT.
