Definitions

  • This invention relates to an electric switch provided ⁇ with a spring-actuated lever arranged between a switch lever and a contact lever, the arran ement being such that this 6 lever jumps quic y onward with a jerk when said spring-actuated lever has moved past the middle point of its path.
  • the spring-actuated lever is turnable on two pins supported in the base of the switch, whereas the switch lever is turnable on one of said pins and the contact lever is turnable on the other of the said pins, and that, secondly, a pin secured to the spring-actuated lever can engage on the one side a recess, which is rovided in the switch lever, ⁇ and the size o which suits to thev extent of the movement of this lever, and can engage on the other side a similar recess provided in the contact lever.
  • the spring pertaining to the spring-actuated lever is located and stretched out between lthe last-men- Iioned pin and a stationary lpoint at the ase.
  • Figure 1 shows a switch designed according to this invention partly in side-view and partly in vertical section, that is to say, the interior of the switch is shown in side-view, and a casing consisting of'a base and a hood shown in vertical section, the switch being shown in closed position;
  • Figure 2 is a vertical (or an axial) section through the switch, the'plane 'of section being turned by 90 with respect to Fig. 1;
  • Figure 3 is a plan of the switch, the hood being removed; and
  • Figures 4 and 5 show the interior of the switch (as in Fig.,
  • 1 denotes the base
  • 2 ⁇ and 3 are two projections thereon.
  • 4 and 5 are two opposltely located lateral recesses in said projections, and form bearings for two pins 6. and 7 projecting forth from the two legs of the spring-actuated lever 8 which is designed as an inverted U.
  • the pin 6 which is located in the recess 4 of -the projection 2, as valready described, serves also assupport for the switch-lever 19.
  • this lever is bent in the manner shown in Fig. 2, land to this portion is aiiixed the grip 20 by means of a screw 21, said grip being located outside the hood 23 which covers and encloses all operating parts of the'switch.
  • a slot 22 In the uppermost portion of the hood is a slot 22 through which the shaft of the grip extends, and below this slot a plate 24 intended to revent dust from entering into the interior o the switch through the slot is affixed to said grip shaft.
  • binding brackets 25, 26, 27 and 28 which are arranged in the manner shown in Fig. 3 and are connectedwith the wires pertaining to the circuit or circuits to be opened and closed by the switch'.
  • the lever or turnable plate 12 is provided with a curved slot 30, andthe switch-lever 19 is provided with a similar slot 29, and the transverse pin 9 of the spring-actuated lever 8 (which lis the lever designed as an inverted U) extends with its projecting free endsinto said two slots, the length of which is determined with res ect to the extent of the of the transverse pin 9 will be located in the lefthand end of the slots 29 and 30 (the slot 29 pertaining to the switch lever 19, and the slot 30 permaining to the contact lever 12, as already described).
  • the switch lever is being moved to the right, first only the spring-actuated lever 8 is taken along with it, Whereas the contact lever 12 remains in its position until the pin 9 has arrived in the righthand end of the slot 30.
  • An electric switch comprising, in combination, a base; a lever forming an inverted U; pins provided at the legs of this lever and engaging recesses of said base; a switch lever supported on one of said pins and adapted to be actuated from the outside of the switch and having a slot; a segment-shaped contact lever supported upon the other offsaid pins and having also a slot a spring connected at one end'with said base and at the other end v cause it to ju-m with thetirst-mentioned lever and being so arranged with respect to it as to be able to v p quickly from one end position into the oter end position; lateral projections at the said first-mentioned lever, these project-ions engaging said slots, substantially as set forth.
