Definitions

  • Fig. l is a longitudinal section through the arrangement according to the invention
  • Fig. 2 a partial longitudinal section through another constructional form and Fig. 3 a longitudinal section through a further constructional form.
  • I is a stationary contact provided at the end of a bar 2.
  • a movable counter contact 3 is fixed to a contact plate 4 and is capable of sliding in the bore of a tubular body 5 consisting of refractory insulating material. This contact is pressed against the stationary contact I by a spring 6 which bears against an insulating plate l.
  • the insulating plate 'l is rigidly connected by means of two bolts 8 and 9 to a flange-like end I0 of the tubular insulating body 5.
  • the bar 2 is extended beyond the ange IIJ and is connected for instance by welding to a current supplying cap II, which forms one external pole of the switch.
  • the movable contact plate 4 is connected to the bolt 9 by means of a exible cable I2.
  • this bQlt 9 is further Connected by means (Cl. 20D-106) of a cable I3 to a second current supplying cap i4, also for instance by Welding.
  • armature I5 Guided along the bolts 8 and 9 is an armature I5, preferably of relatively great mass, which, however, is insulated from the said bolts by insulating tubes IE. 5
  • the armature I5 consists of two tubular halves which are held together by any known means.
  • the armature l5 is held in the position shown by a helical spring ll. It is provided at one end with two l0 pins i8 which are adapted to move through bores I9 in a second flange of the tubular insulating body 5.
  • the movable contact should preferably be arrested in the open po- 35 sition, the coil 2I being at the same time cut out.
  • the contact plate 4 is formed at the side remote from the contact 3 at 22 as a latch.
  • a mating latch 23 which is pivoted at a point 24 40 and is forced by a spring 25 against the latch 22 is provided on one side with a spring extension 26 and, insulated from the latter, a contact 21.
  • a mating contact 28 is connected mechanically and electrically to the bolt 8.
  • a second armature 29 is adapted to slide. It is held by springs 30 in the position shown.
  • the two contacts 21 and 28 are connected by flexible leads 3
  • a second preferably smaller magnet coil 35 is On the outside of the wall of the glass vessel 20.
  • ⁇ magnet coil 35 is energized and draws the armature 29 in to itself, which by means of a finger 36 depresses the latch 23 in opposition to the spring 25, whereby the latch 22 and with it the movable contact 3 is released and is brought through the action of the spring 6 into contact with the contact l.
  • An armature 31 with pins 38 is provided, which is loaded by a spring 39.
  • a magnet coil Q0 is provided, which on being energized draws the armaturel 31 into itself, thereby stressing the spring 39.
  • the armature 31 is left to be acted on by the spring 39, so that it experiences a corresponding acceleration and with its pins-38 strikes against the contact plate d, thereby causing the contacts to open.
  • the contacts I and 3 are fused into the interior of a glass vessel 4I.
  • a glass vessel 4I One part of this glass vessel is made in the form of an elastic corrugated tube 42.
  • the glass vessel is fixed into a tube 43 in any suitable manner for instance by cement 44.
  • the tube 43 is surrounded by a further tube d5, the two tubes together forming a guide for the armature i5, which, as in the case shown in Fig. 1, can be moved by a. magnet coil 2l in opposition to gravity and in opposition to a spring (not shown), so that its pins I8 strike against the contact plate, causing the contacts lA and 3 to be separated.
  • At $6 stops are indicated for limiting the motion of the contact plate and consequently of the contact 3.
