Cam Actuated Patents (Class 200/6B)
  • Patent number: 6079401
    Abstract: In an appliance such as an oven for cooking food, the invention contemplates a user rotatable, single knob oven control device which provides both discrete and continuous control signals to the appliance controller. The discrete outputs indicate selection of oven features, and the continuous output the desired baking temperature. These inputs are selected by a user in response to rotation of a user interface knob mounted on a control panel. The control panel provides visual indication of oven cooking temperature selections through a first arc around the knob, and user selectable oven features (such as, e.g., OFF/CANCEL, BROIL, and CLEAN) in a second arc around the knob. The control device comprises a hub having a portion adapted to be drivably coupled to the user interface knob. The hub also includes a flange which has at least one cam. The device also includes a variable resistance element having a rotatable shaft in driving engagement with the hub.

  • Patent number: 5594220
    Abstract: In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its faces. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into contact with a stationary electrical contact bar that is coated with a noble metal. The spring contacts are configured such that when pressed by a cam the tips are caused to make contact with the stationary contact bar and then slide longitudinally so as the tip will pick up some of the noble metal coating from the contact bar. The tips are shaped with a traverse curve intersecting a longitudinal groove to thereby produce two points that make high unit stress contact with the stationary contact bar.

The switch body is provided with two through holes (13, 14) aligned with the axis of the control shaft (4). One of the holes goes through the mounting plate (3) and the other through an end plate (12), at the opposite end of the switch from the mounting plate. Each through hole allows the shaft to rotate therein as required. The mounting plate (3) and end plate (12) includes a ring recess (15 or 16) for ring (17) serving to limit the angle of shaft rotation. One of the through holes includes a lock (19) for locking against axial movement the assembly formed by the shaft and the cams it controls.

  • Patent number: 4686333
    Abstract: An inner rectangular housing insertable into a cavity of an outer rectangular housing has latching projections on sidewalls near the bottom to latch into latching recesses on inside surfaces of the sidewalls of the outer housing near the cavity entrance. Endwalls of the inner housing have stress ledges near the bottom to deflect outwardly the endwalls of the outer housing to generate permanent tension which is transferred by integral wall corners to the sidewalls of the outer housing to urge them inwardly to maintain the latched condition of the projections and recesses. Such latching and tensioning is useful in the type of electrical switch assemblies whose housings are under long-term stress, vibration and/or heat even when bonded and sealed.

    Abstract: A switch section of a sliding-type DIP switch includes a slider and a pair of opposing contacts each consisting of a resilient metal plate member and having a V-shaped urged portion and a linear portion connected to the urged portion. When the slider is slid, each opposing side wall thereof presses the distal end of the respective urge portion of one contact into contact with the linear portion of the other contact to achieve a reliable electrical switching action. A number of these contact pairs are integrated with the bottom portion of a housing by insert molding to facilitate fabrication.

  • Patent number: 4656321
    Abstract: An electrical switch on a chassis of a magnetic-tape-apparatus has a switching lever movable between a center switch open position, an unstable switched closed position to one side of center, and a stable switched closed position to the other side of center, with an over-center position between the center and stable closed positions. Spaced projections on a head-mounting plate engage the lever during movement between a playing position and a stop/ejection position, so as to cause the lever to move between the center and the stable closed position. With the plate in the stop/ejection position, an actuating rod can pass between the projections to move the lever to the unstable closed position and hold it in that position. When the plate is in the playing position, clearance of the projections from the lever is such that the plate can move a certain distance, for example for fast winding, without engaging the lever.

  • Patent number: 4594483
    Abstract: An impulse generator includes two pairs of contacts and one indexing disk whose indexing notches are capable of moving a central resilient indexing element. The indexing element moves either toward the one or the other pair of contacts depending on the rotation of the indexing disk. Each pair of contacts is a separate contact spring assembly (15, 16; 17, 18). The indexing disk is positioned above the contact springs (15, 16; 17, 18). The indexing element is a spiral spring (10) clamped either at one or at both ends, and disposed in such a way that the centerline (14) thereof extends in relation to the indexing notches (12' and 12) so that the latter deflects the spiral spring (10) laterally toward the contact springs (15, 16; 17, 18). The spiral spring (10) is laterally deflected to actuate the respective inner contact spring (16, 17) of a contact spring assembly (15, 16; 17, 18). This results in reduced abrasive by wear of the indexing disk, and insures that a good electrical contact is reliably made.
