An electric switch for an electric tool with an electric motor. The switch has first electrical terminals for electrical connection to a voltage supply and second electrical terminals for electrical connection to the electric motor. The switch has an actuating mechanism which can be adjusted between an initial position and a final position, wherein the electric motor is switched off when the actuating mechanism is located in the initial position and is switched on when the actuating mechanism is not located in the initial position. The switch also has a braking circuit for braking the electric motor, the braking circuit operating when the actuating mechanism is reset to the initial position. The switch also has a reversal circuit for switching over the direction of rotation of the electric motor. The braking circuit is arranged between the second electrical terminals and the reversal circuit.

Pressure-wave switch

In a switching element, in particular a pressure-wave switch for safeguarding jamming points in the case of operable gates, doors or the like, having at least one pressure chamber which is provided at least partially with a diaphragm (,), it being possible to connect an exciter contact element (,) for making contact with a consumer contact element (,) via the diaphragm (,), it is to be possible for the exciter contact element (,) and/or the consumer contact element (,) to be moved out of a contact plane (E) in order to make common contact.
