Definitions

  • each of the circuit changes to be ellected simultaneously is reduced, or may be reduced, to a simple bipolar change, requiring only three fixed contact members, and a movable contact member.
  • One of the three fixed contact members, viz. a common contact, which is connected to the circuit to be altered, is then electrically connected by the movable contact to one or other of the two other fixed contacts which are respectively connected to the circuit-modifying elements.
  • a known way of partly remedying these drawbacks consists in using a flexible jaw as a fixed contact, inside which jaw a flat ri id movable contact is displaced, said contact having a length such that it is engaged in two jaws simultaneously. But in that case the contact pressures are necessarily high and so therefore is the force required for movement, and the limitation of the latter for an easy operation also means a limitation in the num ber of contact changes to be simultaneously effected. Apart from this and also by reason of high contact prcssures, the resistance to wear of apparatus using this arrangement is small.
  • the present invention has for an object the provision of a switch, the operating movement of which is rectilinear and has only two positions and which allows as many bipolar changes as are necessary to be simultaneously effected, while ensuring that all the contacts made are positive and require only very small force in the maizing.
  • a switch the operating movement of which is rectilinear and has only two positions and which allows as many bipolar changes as are necessary to be simultaneously effected, while ensuring that all the contacts made are positive and require only very small force in the maizing.
  • a two-position electrical change-over switch comprising support means of insulating material, a plurality of flat strip-like fixed contacts carried in line by said support means, a barshaped actuating member of insulating material mounted to slide past said fixed contacts, a bridging contact of ll-shape, the limbs of which are loosely carried by said actuating member, said U-shaped bridging member having a base to bridge between two adjacent contacts of said fixed contacts, and spring means mounted within said actuating member to urge said bridging member in selfaligning manner against said two adiacent fixed contacts.
  • FIGURE 1 shows a front view of a switch, comprising two or more un ts but the two enos only of which are shown, and on of which is sectioned along the line Il of FIGURE 2,
  • FIGURE 2 shows a side view of the unit which is sectioned in FIGURE 1 and also being sectioned along the line ll-l'l of FIGURE 1, and
  • FIGURE 3 shows an end view sectioned along the line llllll of EEGURE l.
  • Each unit is aligned in sequence along the rectilinear line of movement AA.
  • Each unit comprises a fixed portion and a movable portion.
  • the fixed portion of the unit comprises:
  • the ends of the strip whic project on either side, are provided with a recess as shown in the drawings, or with a hole to receive one or more connections.
  • the movable portion of the unit comprises an actuating member consisting of a slider 7 of insulating material, which can be displaced along the rectilinear line of movement AA in one direction or the other, between the two planes of contact and the two insulating plates of the fixed portion, and which has a cylindrical bore 8 transversely therethrough opening at either side toward each plane of contact.
  • a helical spring 9 is located loose in this bore 3 and compressed between two insulating finger iii and iii which respectively slide at each end and which end on the outside in a rounded tip.
  • Movable contacts .2 and 13 are inserted between the slider 7 and each of the planes of contact. These movable contacts are rigid and their section may be round, as shown in the figures, or flat.
  • These movable contacts are U-shaped and the two parallel limbs enter cavities 14 and 15 for the contact 12, and cavities 16 and 17 for the contact 13, said cavities being formed on each side of the slider for this purpose, and the movable contacts sliding therein with a certain lay.
  • the units are assembled within a rigid frame constituted by two end elements 18 and 19, which hold them longitudinally, and by two lateral elements 29 and 21, each having two grooves in which the two insulating plates of the units are respectively located in order to hold them transversely.
  • the guide for the slider is provided by two rods 22 and 23, which are respectively fixed at their ends and which slide in the corresponding member 18 or 19.
  • the movement is a result of a thrust P exerted in one direction or the other on the rod 23. It may be limited either by the play between the slider 7 and the two members lb and 19, or as shown in the figures, by a pin 24 integral with the rod 23 and engaging in th slot 25 in the member 19. This latter arrangement has the advantage, when the rods 22 and 23 are cylindrical, of preventing the rotation of the movable members.
  • the operating device does not form an essential part of the invention, it has no been described; it might however be mentioned that it can be any arrangement which is best suited for the desired use, such as a worm and gear control, a pull-handle, a push-button or a key.
  • the slider 7 is fixed in one or other of the two permissible positions. With it it takes the two movable contacts 12 and 13 which respectively come into position facing two of the three fixed contacts forming the contact planes and at the same time the movable contacts are applied against the fixed contacts under the effect of the pressure exerted at their centre, thus in the middle of the space separating the two surfaces, by the common spring 9 compressed in the bore 8.
  • each of the movable contacts of the unit is alway in engagement with the contact located in the middle of the space separating the two other ones for either position of the slider, a pair of bipolar changes can thus be effected.
  • a two-position electrical change-over slide switch comprising two support members of insulating material mounted to oppose each other, each of said support consist carrying a plurality of sets each of three flat striplike fixed contacts of conductive material, equispatially arranged in line, each set of three fixed contacts on one support member lying opposite a set of three fixed contacts on the other support member, a bar-shaped slider of insulating material mounted to slide between said opposed sets of fixed contacts, a plurality of U-shaped moving contacts, allocated one for each set of fixed contacts, carried in pair on opposite sides of said slider, a plurality of spring means, one for each pair of said U-shaped moving contacts, located within said slider, each spring means normally biassing its associated pair of U-shaped moving contacts outwardly away from said slider to apply said moving contacts in self-aligning manner each against its allocated set of fixed contacts, the base of the U of each U-shaped moving contact being of such size as to bridge across only either two adjacent ones of its allocated set of three fixed contacts, a stud of insulating material between
