Definitions

  • the subject of the invention is a bistable switch with a bistable mechanism, wherein the mechanism and the construction of contacts that provide for the functioning of the fundamental function of a bistable switch, i. e. switching of contacts by means of an electromagnetic drive excited by electric pulses, enables switching of the switch with a minimum energy input.
  • the present invention belongs to class H01 H 51/08 of the international patent classification.
  • bistable switch The technical problem satisfactorily solved by the present construction of a bistable switch is such construction of the switch and its mechanism that requires minimum energy for switching and is also construed in a simple and price efficient way.
  • a switch mechanism designed by means of a toothed wheel according to the patent document EP 1024511 does not allow to switch large loads, since the forces needed for switching would cause too much friction.
  • Another solution is a switch mechanism based on the principle of a heart- shaped anchorage according to patent documents WO0186682 and EP1901327.
  • a drawback of this solution is that the switching off is effected at the second step, which means that the switch switches off only when the coil is without voltage or when the button is released in case the switch is switched manually.
  • a rocker arm mechanism of the patents EP0641000 and EP0641003 does not include switching of contacts by way of a contact bridge.
  • the bistable switch with the bistable mechanism of the invention solves requirements for an energy-saving mechanism that simultaneously provides for coupling of contacts intended for large loads in a way that a spring of a rocker arm 6 is fastened onto a lever 1 and a rocker arm 3, wherein bridges 4 and 5 are fastened to the latter symmetrically to the axis of rotation of the rocker arm 3.

  • Figure 5 schematic view of the mechanism of the bistable switch of the invention for a variant with two closing contacts in open state
  • Figure 6 schematic view of the mechanism of the bistable switch of the invention for a variant with two closing contacts in closed state.
  • the bistable switch with the bistable mechanism of the invention comprises a rocker arm 3 centrally pivoted in the switch housing and having a plug 11 , onto which a spring 6 of the rocker arm 3 is fastened.
  • a lever 1 is fastened within the housing and reaches with a plug 19 through an oblong groove in the rocker arm 3.
  • the lever 1 serves as a position indicator, a button for manual coupling of contacts 13, 15 and a holder for fastening the spring 6 of the rocker arm 3.
  • the spring 6 is fastened by means of a plug 7 for constructions with one opening and one closing contact and with a plug 8 for constructions with two closing contacts.
  • the force needed for coupling of contacts or contact springs is herewith optimized.
  • a bridge 5 serving as a holder of an opening contact bridge 14 and a contact spring 18 is fastened with an oblong groove onto a plug 12 positioned on the rocker arm 3 symmetrically to the axis of rotation of the rocker arm 3 with respect to the plug 10, onto which the bridge 4 is fastened, wherein the bridge 4 serves as a holder of a closing contact bridge 13 and a contact spring 17.
  • This type of fastening requires a smaller number of needed contacts 16, 15.
  • two bridges 4 are fastened onto the rocker arm 3, namely one onto the plug 10 and one on the second side of the rocker arm onto a plug 20 arranged in the same position.
  • Switch-over energy is ensured by an electromagnet, a constituent part of which is an anchor 9.
  • the anchor 9 presses against a forcing means 2, which transfers this force to the rocker arm 3.
  • the rocker arm 3 converts the linear movement of the forcing means 2 into a torque that moves the bridges 4 and 5 via plugs 10, 20 and 12.
  • the bistable switch of the invention can also be switched manually.
  • the lever 1 is acted upon and oscillates around the fastening in the housing and drives the rocker arm 3 via plug 19.
  • the rocker arm 3 in turn moves the bridges 4 and 5 via plugs 10, 20 and 12.

Abstract

La présente invention a trait à un commutateur bistable doté d'un mécanisme bistable, lequel commutateur bistable est conçu de manière à ce qu'un ressort (6) d'un bras oscillant soit fixé sur un levier (1) et sur le bras oscillant (3) et de manière à ce que, symétriquement à l'axe de rotation du bras oscillant (3), des ponts (4, 5) soient également fixés sur ledit bras oscillant (3), ce qui permet de commuter le commutateur suivant diverses combinaisons de contacts avec un apport énergétique minimal fourni par un électroaimant ou un bras en cas de commutation manuelle.
