  • Patent number: 4801770
    Abstract: A switch assembly in which a lever rotates a separate rotary member to operate a first electrical switch and the lever pivots within the rotary member to operate a second electrical switch. The rotating member is held at a first position and a second position when the rotary member is turned. A solenoid is linked to a cam that restores the lever to a neutral position between the first and second positions. A return mechanism returns the pivoting member to its original position when the lever is released.

  • Patent number: 4569253
    Abstract: A vehicle automatic transmission including a torque converter, a multiple stage transmission gear mechanism connected with the torque converter and a hydraulic control circuit for automatically selecting one of gear stages of the transmission gear mechanism. The hydraulic control circuit includes a kickdown control device which functions to shift down the gear mechanism when the engine control foot pedal is substantially fully depressed. Depending on the vehicle running condition, the kickdown control device shifts down the gear mechanism by two gear stages. The hydraulic circuit includes control circuit which functions to shift down the gear mechanism at first by one gear stage and then by a further one stage in sequence when a two stage shift down is required.

Depending on the vehicle running condition, the kickdown control device shifts down the gear mechanism by two gear stages. The hydraulic circuit includes control circuit which functions to shift down the gear mechanism at first by one gear stage and then by a further one stage after a certain time delay when a two stage shift down is required.
