A device for switching and controlling electrical apparatus, has a guide bearing for creating haptics indicating the position of the device. The guide bearing has one bearing part constructed as a switch housing and one bearing part constructed as an actuating element. The guide bearing has a control path formed on one of the bearing parts and a rolling-body mount constructed on the other bearing part. A rolling body is held in the rolling-body mount. A haptic spring presses the rolling body onto the control path. The structure of this device is suitable for creating haptics, without the operational reliability and service life of the guide bearing being appreciably impaired.

A push button encoder comprises a push button, a base that supports the push button, and a printed circuit board. Pushing the push button engages the printed circuit board and thereby causes the printed circuit board to output an electrical signal. A spring resiliently supports the printed circuit board with respect to the base such that the printed circuit board is movable with respect to the base when the push button is pushed.

Disclosed are various forms of hand-held communication devices which serve as alternatives to a keyboard and which, in addition, allow the user to receive communications via the sense of touch. Although not so limited, the device is well-adapted for use by persons who are speechless, deaf and speechless, or even blind, deaf and speechless. The present invention provides particularly compact and efficient finger movement actuated communication devices for individually responding to thrust and push motions of at least one finger of a person's hand. Thus, each finger can operate two switch elements, and the four fingers of a person's hand can operate eight switch elements in predetermined combinations suitable, for example, for communication in a binary code. In a first disclosed embodiment, a handle-like body supports eight switch actuators arranged as four pairs, with each of the pairs corresponding to a particular finger. The two switch actuators are positioned for selective activation by distal and proximal segments of a single finger. In a second disclosed embodiment, four switch actuators are provided for actuation by the fleshly portions of a person's fingertips. Each of the switch actuators supports two distinct types of movement, pushing and sliding, and corresponding operate a pair of switch elements. In a third disclosed embodiment, collar-like rings are worn about the proximal and middle segments of the user's hand. Relative motion between the collar-like rings and a wrist harnass is sensed in order to respond to thrust and push motions of the fingers.

A push button switch comprises a key top having a recess and a resilient member provided so as to surround the recess of the key top. The resilient member has a projected portion extending therefrom in the direction away from the recess of the key top, and at least the end of the projected portion is formed of conductive material. A contact member is secured to a base plate in opposed relationship with the projected portion. A holder member holds the key top in such a manner that the projected portion of the resilient member is normally spaced apart from the contact member but engages the contact member upon depression of the key top.
