Abstract: A pedal displacement sensor includes an actuating lever and a switching element. The actuating lever is arranged in a housing, is rotatably supported on a rotational axis, and can be rotated by a pedal. The actuating element of the switching element is actuated by rotating the actuating lever. The housing of the pedal displacement sensor has an opening. The actuating lever extends through the opening to an end which engages the pedal. The actuating lever includes first and second arms which form an angle lever. The first arm is rotatably supported in the housing. The second arm extends through the opening to an end face which contacts the pedal lever. The actuating lever preferably also acts upon a transducer such as a Hall sensor and a permanent magnet.

Abstract: An apparatus is disclosed for coordinating the operation of multiple devices actuated by foot pedal operated switches. A housing has a lid movably mounted thereto and defines a recess therewithin. A foot pedal assembly has a pedal member which is downwardly movable and which is adapted to be depressed by downward pressure exerted by the foot of a user. The foot pedal assembly has a first switch operatively associated therewith which is actuated by a downward movement of the pedal member. The foot pedal assembly is disposed within the recess defined within the housing such that a downward movement of the lid displaces the pedal member of the foot pedal assembly to actuate the first switch. A second switch is disposed such that the downward movement of the lid of the housing also actuates the second switch. Downward movement of the lid actuates the first and second switches together to concurrently change the states of first and second devices operatively associated with the first and second switches.

Abstract: A dual position foot pedal includes a base and pedal arrangement which enables access by one of the user's toe and a user's sole for manipulation of the pedal. Switching between the two pedal positions is achieved by rotating the pedal. In this manner, the foot pedal combines the functionality of two common surgical foot pedal types in one pedal.

Abstract: A foot actuated pneumatic switch for use in association with food-equipment such as mixer-grinders. The switch includes a u-shaped compressible pedal and a hemispherically shaped rubber actuator. The operator applies pressure to the pedal thereby depressing the actuator and initiating operation of the equipment. The pedal operates by means of a spring-like operation which enables the pedal to return to its static position when the pressure on the pedal is removed.

Abstract: A flat foot switch unit has a surface has a slippage-preventing measure. In this, a foot switch section has a four-sided surface shape and step-motion-detectable foot switches internally formed in nine regions by dividing the surface shape in 3×3. Furthermore, the foot switch section has slippage-preventing linear grooves at least in the regions on the surface of the top layer of a first sheet unit, which is part of the surface shape, and in which the foot switches are arranged.

Abstract: The invention relates to a modular electrical contact in which the electrical components are separated in a separate module, and in which the others of the modules of the contact are built without electrical components. An advantageous embodiment according to the invention comprises a mechanical motion transmission advantageous for the purpose, where one or more contacts (53) may be activated through pressure operation. The device comprises a guide rail (52) with an activating element (51) which comprises a pressure element (55) and an extension element (54) and arranged with fixing means with respect to the guide rail so that the pressure element is slidable therein for activation of one or more contacts (53) arranged at the end of the pressure element. This provides an extremely simple, sturdy and flat structure which is simple to manufacture and simple to mount. This operating device is particularly suitable for use in foot pedals.

Abstract: This invention discloses a safety controller for use with a power switch for turning on or off the power switch. Two pressing actuators are provided in the design of the control pedal of the invention, having slant surfaces tilting in opposite directions. When the user steps on the control pedal, the first pressing actuator presses the button on the power switch to turn on the power; whereas when the control pedal is restored, the second pressing actuator presses the button on the power switch to turn off the power.

Abstract: A foot control assembly for a microsurgical system for controlling a plurality of ophthalmic microsurgical instruments connected thereto. The microsurgical instruments are for use by a user such as a surgeon in performing ophthalmic surgical procedures. The system includes a data communications bus and a user interface connected to the data communications bus. The user interface provides information to the user and receives information from the user which is representative of operating parameters of the microsurgical instruments. The system also includes surgical modules connected to and controlling the microsurgical instruments as a function of at least one of the operating parameters. The surgical modules are also connected to the data communications bus. The data communications bus provides communication of data representative of the operating parameters between the user interface and the surgical modules.
