The present invention relates to a circuit arrangement, having a power circuit and a control circuit, in which the power circuit with the control circuit is activatable and deactivatable, and the power circuit is activatable only when the power circuit is switched on and is deactivatable only as long as the power circuit is switched on. The present invention further relates to a switch device, which includes an actuator as well as a first switch for switching a power circuit and a second switch for switch a control circuit of a circuit arrangement, in which the first switch and the second switch are switchable by actuation of the actuator, and the second switch is switchable only when the first switch is switched. The present invention also relates to a method by which a power circuit of a circuit arrangement, is activatable or deactivatable, in which the circuit arrangement includes the power circuit and a control circuit, and the power circuit is switched on before it is activated by switching on of the control circuit. The present invention also relates to a handheld electric power tool, including a switch device.
