Definitions

  • the present invention relates to electrical switching devices.
  • a switch device comprises an actuating member mounted for movement from an idle position towards an operating position, a second member mounted for movement between a normal and an actuating position relatively to the first member, a mechanism to interconnect the two members for joint movement upon actuation of the first member when the members are in their normal relative position, a finger bearing upon surfaces in the two members and adapted when held in a first position to prevent actuation of electrical contacts and in a second position to cause or allow actuation of said contacts, said surfaces being so shaped that when said members are in their normal relative position the finger is held in the first position throughout the movement of the actuating member and when the said members are in their actuated relative position a depression is formed whereby said finger can move into its second position, and a detent device to detain the second member after it is moved with the first member, upon movement of said first member from idle to operating position, whereby upon return of said first member to idle position said members will be in their actuating relative position. Additional spring means are preferably provided to urge said second
  • Fig. 1 shows a switch device according to this invention in the normal or unactuated condi- Fig. 2 shows the switch after depression of the actuating member
  • Fig. 3 shows the switch after release of the actuating member
  • Fig. 4 shows the device of Figs. 1 to 3 in perspective in association with means for moving the detent device between an operative and an inoperative position
  • Fig. 5 shows a rotary switch according to this invention.
  • a push button I is mounted for limited sliding movement to left and right and carries an actuating member 2 having a first cam surface 3 and a second cam surface 3.
  • a compression spring It is provided to urge the member 2 towards the left in the drawings.
  • the member 2 carries two pins d located in slots 5 in a member 6. The slots permit limited sliding movement of the member 6 upon the member 2 and a tension spring I5 is provided tending to maintain these members in the position of Figs. 1 and 2.
  • the spring l5 may alternatively be between the two members 2 and 6 instead of as shown between the member 6 and the front panel l6 which is fixed to the frame I.
  • the member 5 also has a cam surface 8.
  • a spring blade finger 9 controlling the actuation of contacts It is spring-biased by its inherent resilience to bear on the cam surfaces on members 2 and 6.
  • a detent spring H fixed to the frame I has a catch member l2 pressed upwards against the under surface of the member 5 by the action of the spring II in Fig. 1.
  • the switch can be restored from the position of Fig. 3to that of Fig. 1 by depression of a selector finger 13 thereby allowing the member 6 to assume its intical position relative to member 2 as shown in Fig. 1.
  • a spindle H" is shownprovided with a cam surface It in the form of undulations 'or'teeth which on rotation of the spindle raises and lowers a pawl l9 connected to the selector finger l3 at settings at which actuation is desired and not desired respectively.
  • the pawl l9'i's held by a spring 28 in engagement with the cam surface I8. If the switch is in the position of Fig. 3 and the spindle ll is rotated, the finger l3 will be depressed and the contacts [0 opened. Further, the push button l, when depressed and released, will be capable of actuating the contacts it only in those positions of the spindle l! in which the finger I3 is in its upper position.
  • the release of the switch can be under the control of more than one other element.
  • a second suchfing'er is for example indicated in Fig. 4 at 2!.
  • a cam-shaped disc 2 is rigidly attached to a spindle I and is held against a suitable stop 22 by means of tension spring l4 operating to turn the disc 2 in the direction of the arrow A.
  • a second disc 6 is arranged to rotate freely around the spindle l, a pin 4 attached t the disc 2 operating in a kidney-shaped slot 5 in the disc 6.
  • This disc is also urged in the direction of the arrow A by means of a suitable tension'spring [5 thus allowing for relative rotary movement of the two cam surfaces 3 and '8 either by release of the 'detent l l or by operation of the spindle l in the direction of arrow B.
