    摘要: An electronic power apparatus is provided, including a circuit board having a conductive pads and a sense pad coupled to an output signal, and an actuator having a wiper portion accommodating a conductive wiper. The wiper includes a first end arranged to engage the sense pad and a second end arranged to slidably engage at least one of the conductive pads on the circuit board. The conductive pads are arranged in a first row of conductive pads and a second row of conductive pads in parallel with and at a distance to the first row of conductive pads. An alignment of the second row of conductive pads is offset with respect to the first row of conductive pads.

    摘要: The resistor unit (10) comprises resistors (12,14,16) connected to electrical terminals (24,26,28,30,32) secured to an insulating plate to which first and second legs (64,66) of a spring sheet metal mounting clip (60) are secured for insertion through an opening in a supporting wall. The legs (64,66) are bent forwardly from a rear member and are formed with first and second spring latching members including ramp portions bent laterally from the legs (64,66), shoulder portions bent inwardly from the ramp portions for wedging engagement with edge portions of the wall, and front end portions bent forwardly from the inner ends of the shoulder portions. A soft resilient expanded rubber gasket is mounted on the plate for sealing engagement with a rib projecting forwardly from the wall around the opening. The spring force produced by compression of the gasket is counterbalanced by the wedging action of the shoulder portions, so that rattling is prevented. The legs (64,66) are inserted with an interference fit into opposite end portions of the opening. The rear clip member and the opening have similar nonsymmetrical shapes affording unique orientation of the resistor unit (10). The clip (60) also protects the resistors from damage during shipment.

    摘要: A plurality of equally spaced terminals are disposed on a substantially uniformly resistive thin film at one side edge of the film. A reference potential (e.g. ground) is applied to the second side edge of the film. An energizing voltage is applied to the film at the juncture between the first side edge and a particular one of the top and bottom edges of the film. In this way, voltages are produced at the successive terminals with a logarithmic relationship with respect to the terminal positions. When a linear relationship is desired between the voltages at certain successive terminals in the low range and such terminal positions, no reference potential is applied to the second side edge of the thin film at the vertical positions corresponding to such terminals. Instead, the reference voltage may be applied to the other one of the top and bottom edges. Alternatively, no such reference voltage may be applied and terminals may be disposed at such other edge to produce the linear relationship. Each of a plurality of comparators receives an input voltage and the voltage at an individual one of the successive terminals. The comparators provide an output indicative of the input voltage. The voltages on the successive terminals in the first portion of the thin film may be calibrated by a circuit including a capacitance to indicate possible voltage deviations from the logarithmic relationship. The successive terminal voltages in the second portion of the film may be calibrated by the capacitance circuit and a constant current source to indicate possible voltage deviations from the linear relationship.
