Abstract: A power tool for chiseling and drilling includes a housing, a motor disposed inside the housing, and a pneumatic percussion mechanism. An operation mode selector switch is disposed on the housing and has a first operation mode setting and a second operation mode setting where the first operation mode setting activates the pneumatic percussion mechanism and the second operation mode setting deactivates the pneumatic percussion mechanism. A valve has an inlet-port formed inside the guiding tube and an outlet-port formed outside the guiding tube where the valve is connected to the operation mode selector switch. The valve is closed in the first operation mode setting which disables an air exchange between the inlet-port and the outlet-port and the valve is open in the second operation mode setting which enables the air exchange between the inlet-port and the outlet-port.

Abstract: A pouch cell having at least one connection electrode via which the pouch cell can be electrically contacted, wherein the pouch cell includes a current interrupter configured, by virtue of a thermally induced change in its geometric dimensioning, at least temporarily to interrupt drawing of current via the connection electrode. Preferably, the current interrupter includes a material having a negative coefficient of thermal expansion, wherein the thermally induced change in its geometric dimensioning is brought about by a change in a pouch cell temperature.
