  • Method and apparatus for controlling an appliance having a switch blade which includes staggered electrical contacts
    Patent number: 5910649
    Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.
