Definitions

  • a push-button switch comprising a first and second magnet means for attracting one another, a push button ha ving the first magnet means disposed at one end thereof, and an operating member movably disposed adjacent the push button and having the second magnet means thereon adjacent the first magnet means.
  • Two fixed contacts spaced from each other, are provided as well as a contact member coupled to the operating member for movement therewith between the two fixed contacts, respectively, and a spring means for urging the operating member in a direction opposite to the direction in which the operating member is urged by the first and second magnet means for causing the contact member to engage one of the two fixed contacts.
  • the first and second magnet means are of sufficient magnetic force to cause the operating member to move toward the push button against the force of the spring means so that the contact member engages the other of the two fixed contacts when the push button is moved toward the operating member, and a means is provided for adjusting the spring means to vary the force of the latter against the operating lever to thereby change the switching time of the push button switch.
  • the present invention relates to a push button switch, in general, and to an adjustable push button permanent magnet switch, in particular.
  • a push button switch which is adapted for electrical connections, can be formed as a closing switch, opening switch and alternator.
  • the switching force is created by pre-tensioning of a spring for each connection, the switching force is obtained in accordance with the present invention from a permanent magnet.
  • the tensioning force of the switch spring is not variably controllable.
  • the switching procedure is controllable.
  • a button head carries on the inside of the switch a permanent magnet, the magnetic field of which pulls in the controllable pressed-in position of the button, an operating lever cooperating with an abutment member and charged with an adjustable compression spring and coupled with a contact lever.
  • FIGURE 1 is a cross-section of an alternating switch 3,373,386 Patented Mar. 12, 1968 indicating the respective contact positions, as well as the open position;
  • FIG. 2 is a cross-section of the same switch, however, in a closed position.
  • the push button switch comprises a switch housing 17 in which contacts 1,2 and 5 are disposed.
  • the contact carrier 5 carries a pivotal contact lever 3, which performs a pendulum movement between the contacts 1 and 2 about its pivot point 4.
  • a button 14, which is equipped with a permanent magnet 13, is maintained in its original position (FIG. 1) by means of a spring 15, the force of which is controllable by a button head 16. If the button is pushed by means of the button head 16 in direction of the arrow, indicated in FIG. 1, the permanent magnet 13 reaches with its effective range the iron plate 12, and attracts the latter, and, thereby, the contact lever 3 by means of the coupling member 8, is moved in the direction towards the contact 2.
  • the permanent magnet 13 and the iron plate 12 constitute a first and second magnet means, respectively.
  • An abutment 11 limits the lifting of the lever 6, which remains in this position until the button 14 is released and returns in the direction of the arrow, shown in FIG. 2. By releasing the button, the magnet 13 becomes released from. the iron plate 12 due to the restraining action of the abutment member 11 freeing the lever 6, so that the latter is pushed back by the spring 10 into the position disclosed in FIG. 1.
  • a push button switch comprising a first and second magnet means for attracting one another
  • said operating member is a lever pivotally mounted at one end remote from said push button, said second magnet means disposed at the other end of said lever, and said spring means engages said lever between the ends thereof and extending parallel to the axis of said push button.
  • one of said magnet means is a permanent magnet and the other is an iron plate
  • said operating member is a lever pivotally mounted crosswise to the axis of said push button, said spring means disposed above the coupling of said contact member to said operating lever,
  • said means for adjusting said spring means comprising an adjustable screw engaging one end of said spring means
  • abutment means cooperating with said lever for separating said permanent magnet from said iron plate when said push button is moved in a direction away from said lever.
