    Abstract: A control device processes or agricultural sprayer. A slip member biased by a retaining member and springs to an initial neutral position produces a signal by a sensor upon initiation or cessation of angular forces from rotation of a machine driven shaft. The signal is caused by movement of the slip member from friction produced by an impeller situated within the grease filled slip member. The impeller is coupled directly or indirectly to the machine driven shaft and rotates upon rotation of the shaft. Upon initiation of angular forces on the impeller, the signal produced may cause a valve on an agricultural sprayer to open and initiate spraying therefrom. Upon cessation of angular forces on the impeller, the valve may be closed to turn off the spraying.

A piston which transmits the movement of the actuator lever to the microswitch is supported air tight by the housing at the center of a flat conical bellows, and the limit switch including a return coil spring is highly sensitive, and is excellent in water resistance, oil resistance, abrasion resistance and durability.

  • Patent number: 6655626
    Abstract: A belt retractor for a vehicle safety belt includes a frame, a belt spool rotatably mounted in the frame, and a locking mechanism which is provided with a release disk and by means of which the belt spool can be blocked against rotation in the frame. The belt retractor further includes a control disk as well as a reduction gear that couples the belt spool with the control disk. A rocking lever is provided which is adapted to be pivoted by the control disk between a release position in which it does not cooperate with the release disk, and a blocking position in which it engages in the release disk, whereby the belt spool can be blocked against rotation. A switch is provided which is adapted to be actuated by the control disk when a predetermined amount of belt webbing has been drawn off the belt spool and the control disk has been turned into a predetermined position.

  • Patent number: 6646212
    Abstract: A switch mechanism comprising a housing in which a switch is mounted, the switch being actuable to switch between first and second conditions. A cam is mounted within the housing to rotate about a predetermined cam axis, the cam defining a cam surface against which a cam follower bears such that rotation of the cam causes displacement of the cam follower to activate the switch. An actuator shaft which may be connected to a safety rope is mounted to be axially displaceable within the housing, the actuator shaft being mechanically coupled to the cam such that axial displacement of the shaft causes the cam to rotate about its axis. The actuator shaft is positionable in an intermediate axial position in which the cam is rotatable to a predetermined rotational position such that the cam follower causes the switch to assume the first condition.

  • Patent number: 6605793
    Abstract: The switch includes a microswitch switching mechanism having a biassed plunger. The body of the switching mechanism is covered by a lid having a user-operated slider mounted thereon. Movement of the slider is confined to a track formed in the lid. A cam surface is provided on a part of the slider which is engageable with the plunger of the switching mechanism. The “over-centre” profile of the cam surface is such that movement of the slider in one direction causes the plunger to be depressed and then released. Inadvertent operation of the switch is avoided due to the cam profile.

  • Patent number: 6441332
    Abstract: A switch assembly includes both a separating wedge member, which functions to maintain two electrical contacts out of electrical communication, and a second, camming element, which can be used to squeeze the contacts together when the switch assembly is actuated. In a first embodiment, the second element is of a generally conical shape. In a second embodiment, the second element is actually constituted by two side members having ramped surfaces. The interaction of the specially shaped contacts and camming element ensures proper mating of the contact members when the switch is actuated. In one preferred form of the invention, an undulating channel is formed in a housing of the switch to pinch connecting wires and assure a positive, reliable connection with the contacts.

  • Patent number: 6310529
    Abstract: The present invention is for a bi-stable battery switch incorporated preferably for internal use into a remotely switchable storage battery, or, in the alternative, for external use with a battery. A bifurcated contact assembly incorporating dual bus bars is pulse actuated by a solenoid and cam arrangement to engage or disengage across opposing contacts. When engaging the contacts and when associated with high inductive loads, the first bus bar to advance initiates contact and assumes the arcing load, while the second bus bar to advance assumes the current load. When breaking contact and when associated with high inductive loads, the first bus bar to retreat breaks the current load and the second bus bar to retreat breaks the arcing load. Thus, the loads are shared to increase the durability and length of service of the switch.

  • Patent number: 6278619
    Abstract: The invention concerns a disconnecting appliance, such as a switch, a fuse-disconnecting switch or breaker-reversing switch, having a novel arrangement of fixed and moving contacts promoting contact surface self-cleaning and increasing contact force for the same contact force applied by the cam. Moreover, it comprises a newly designed cam for actuation the mobile contacts to optimize to the maximum the operating conditions when engaging and releasing. The appliance is characterized in that the moving contacts (35, 36) comprise two contact surfaces (38) arranged in substantially perpendicular planes, corresponding with those (27) of the fixed contacts (31, 31′ and 33, 33′), each moving contact (35, 36) moving in radial translation relative to the control shaft (23) along a direction (F) substantially perpendicular to a straight line passing through its two contact surfaces (38).

    Abstract: A microswitch is provided with a push lever having a ball at a lower end so as to roll freely. A seesaw contact piece has one side piece to which a movable contact is attached and an opposite side piece to which the ball of the push lever is in constant contact when external force is not applied to the push lever. A fixed contact switches ON by coming into contact with the movable contact and switches OFF by separating from the movable contact. A fixed contact piece is configured to support a comer part of the seesaw contact piece.

  • Patent number: 6180898
    Abstract: An emergency stop switch mechanism for a robot which can take an emergency position when an external operation force is released and when a strong external operation force is applied. When the robot operation is started, a main lever La is pushed down from the OFF state with a normal external operation force. Since an elastic biasing force S2 is sufficiently larger than S1, a second ancillary lever Lc is pushed by a plunger PL and is turned downward together with a first ancillary lever Lb. A movable contact element ME of a contact mechanism section CM is moved to the ON position by the second ancillary lever Lc, so that the ON state (motion permitting state) is established. If emergency stop becomes necessary, the pressure of the main lever La is released from this state, or a specially strong force is applied to the main lever La. When the former is selected, the movable contact element ME is returned to the OFF position.

  • Patent number: 6180903
    Abstract: A tact switch comprises an insulative base having contacts partially retained therein and partially exposing to exterior, wherein the exposed portions of the contacts face upward. Two separated steps are formed in the insulative base and located beyond the exposed portions of the contacts. A conductor plate has a frame positioned on the separated steps, an integral contacting portion surrounded by the frame and connected to the frame via two spring arms. Normally, the contacting portion registers with and separates from the exposed portion of the contacts. An elastic device is positioned on the conductor plate and it is deformable by depression thereon to thus deform the spring arms of the conductor plate and move the contacting portion of the conductor plate downward to electrically connect the exposed portions of the separated contacts simultaneously.
