Abstract: A switch apparatus for use with a device. The switch apparatus includes a letter ring, associated with an operation member, that rotates together with a selection dial. The letter ring contains inscriptions, such as marks or figures thereon. A decorative plate includes a pointer to indicate the selected function. A rotation of the rotatable operation member causes a plurality of electrical conductors to change their ON/OFF electrical state. The plurality of electrical conductors form a code pattern representing a code that is interpreted by a control circuit to determine an operation mode selected by the rotational operation member. The switch apparatus further includes a push button that is depressed to, for example, activate a modification of the operation mode based upon the data of the code pattern of the code.

Abstract: A non-sparking rotatable switch apparatus for a multi-speed fan includes stationary contacts positioned at two different levels relative to a plane of rotation of the switch. The rotatable portion of the switch apparatus includes upwardly extending contact sheets, some of which extend only to the lower level at which contacts are positioned and at least one of which extends to the higher level at which contacts are positioned. The higher level upwardly extending contact sheets have different widths than the lower level sheets, thereby changing the timing at which the upwardly extending contact sheets engage the respective contacts.

Abstract: A tease-proof rotary switch has a driving shaft which is coupled to a driven shaft through a coupling spring. The driven shaft is connected to a rotating switch assembly. The driving shaft rotates, storing energy in the spring which, in turn, can rotate the driven shaft. The energy stored in the spring may be sufficient to start the rotation of the switch and to seat it in the next stable switch position. Alternatively, the driving shaft can engage an element of the driven shaft to start the rotation which can then be completed to the next stable position by the energy stored in the spring.

Each of the contact arms includes a cam follower, at least two of the cam followers being equidistant from the center of the contact member. The cam followers are operatively engaged, in a predetermined sequence, by camming elements extending axially from the bottom surface of a rotor mounted in the chamber above the contact member. The equidistant cam followers are engaged by camming elements that are spaced from the center of the rotor by a distance equal to the distance separating the equidistant cam followers from the center of the contact member.

Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member. The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved. The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.
