Ultrasonic surgical instruments including a handle housing, a switch frame, and a switch assembly are disclosed. The switch assembly may include a first switch arrangement movably supported on a distal portion of the handle housing and selectively movable relative to a first switch contact supported by the switch frame. The switch assembly may further include a second switch arrangement including a right switch button movably supported on a right side of the handle housing and selectively movable relative to a right switch contact supported by the switch frame, and a left switch button movably supported on a left side of the handle housing and selectively movable relative to a left switch contact supported by the switch frame. The first and second switch arrangements may be configured to be selectively actuatable by a single hand supporting the handle housing.

A switch assembly comprises a button, a pivoting element, a first positioning element, and a second positioning element. The button has a first, second, and third states. The pivoting element extends from a height direction of the button, and has first and second contact parts arranged in the height direction. Surfaces of the first and second contact parts have different contours. The first positioning element and the second positioning element respectively correspond to the first contact part and the second contact part, and are movable relative to each other. A function of the first positioning element and a first positioning section of the first contact part is configuring the first state, and functions of the second positioning element and a second positioning section and a third positioning section of the second contact part are respectively configuring the second state and the third state.

A mechanical switch (10), in particular a light switch and/or a roller shutter switch and/or thermostat switch is provided. The mechanical switch (10) has a switching contact assembly (20), in particular a monostable, bistable or tristable switching contact assembly (20), and a base carrier (40), in which the switching contact assembly (20) is received The base carrier (40) has a holding device (50) for receiving an electromechanical actuator unit (100), which is designed in such a way that an electromechanical actuator unit (100) received in the holding device (50) can be supplied with voltage for effecting a state change of the switching contact assembly (20) independently of an external mechanical action on an operating mechanism by means of the electromechanical actuator unit (100).

In a rocker arm of an electric switch, the electric switch is actuated by the rocker arm for setting definable positions. The rocker arm of an embodiment includes a first part, for setting the definable positions, and a second part, movable between a first position and a second position. In the first position of the second part, the first part can be moved into the definable positions; and in the second position of the second part, the movement of the first part is blocked.

A rocker switch includes a rocker switch housing and a first magnet sensor. The rocker switch further includes a button rotatably mounted to the rocker switch housing about a first axis. The rocker switch also includes a magnet holder in contact with the button and rotatably mounted to the rocker switch housing about a second axis different from the first axis. The magnet holder holds a first magnet having a first polarity and a second magnet having a second polarity different from the first polarity. When the button is in a first button position, the button biases the magnet holder to a first magnet holder position, in which the first magnet is proximate to the magnet sensor. When the button is in a second button position, the button biases the magnet holder to a second magnet holder position, in which the second magnet is proximate to the magnet sensor.
