An electric switch, in particular for manually operated electric tools or appliances with an electric motor, is switchable from outside by means of a plunger. A changeover device is provided for setting the direction of rotation of the electric motor, which changeover device can be activated for example by a tappet arranged on the outside. The switch is constructed very compactly, which simplifies the sealing of a switch of this type.

A safety device (8) with a safety switch (7) and at least one actuator (9), wherein when an actuator (9) is arranged within a response range relative to the safety switch (7), signals are transmitted from the actuator (9) to the safety switch (7), by which means a function of the safety switch (7) is released. The actuator (9) is additionally designed for configuring the safety switch in that a configuration signal is transmissible from the actuator (9) to the safety switch (7).
