PRESS-BUTTON SWITCH.
Application filed July l5,
To all whom 'it may concern:
Be it known that I, HUGO SACHS, a citizen of the German Empire, residing at Leipzig, Germany, have invented certain new and useful Improvements in a Press-Button Switch, of which the following is a specification.
My invention refers to an electrical pressbutton switch in which two press-pieces concentrically guided in each other are disposed, one of which alternately overreaches the other piece, hereby indicating the position of the contact. Further the locking and the loosening of the contact elements are produced by means of two catches pivotally mounted on a movable rod in such a way that the same form a knee-lever which requires a minimum of force for the cut-outaction.
In the drawings Figures l and 2 are sectional views of the improved switch shown respectively in the open and closed positions.
The knob 2 is mounted on the contact carrier 5 kept in the position shown by means of the spring 12. The contact pieces 6 are separated from the carrier by the insulation 4. The sleeve 3 contains the catch spring 13 and the press-button rod l0 on which both catches 9 and 11 are pivotally mounted. The press-button l is fastened to the top of the rod lO. The contact springs S are mounted on the base plate lll.
The device works as follows:
The knob 2 being pressed down the spring l2 is compressed and the contact carrier 5 pushed down making the contact pieces 6 mesh with the contact springs 8. At the moment the enlarged upper end of the carrier 5 arrives at the height of the catches 9 and ll the pressure of the spring 13 exercised upon the rod causes the catches to 1920. Serial No. 396,620.
extend through the openings in the sleeve thus fixing the contact carrier 5 in its effective position. The switch is brought back into its out out position, shown in the drawing, by a pressure upon the now salient press-button l. In this way the catches are pushed down into the sleeve 3, thus freeing the carrier 5 in turn pushed upwards by the compressed spring l2, whereby the conta-ct is rapidly interrupted.
I claim:
l. A press button switch comprising normally open contacts, an operating member for closing said contacts, locking means within said member, and means moving independently through said operating inember to release the locking means.
2. A press button switch comprising normally open contacts a reciprocating member to close the contacts, yieldable means biasing said member to an open position, locking means within the member to hold the contacts closed and shiftable to locking position upon movement of the member to close the contacts, and means slidingly through the member and operable independently thereof to release the locking means.
t). casing, normally open contacts therein, a reciprocating knob movable through the casing wall to close the contacts, yieldable means to bias the knob to an initial position with the contacts open, said knob having an extension in the casing, a slotted sleeve in the casing enveloped by said extension, toggle catches operating through the slotted sleeve againstl said extension, and a push button mounted to slide axially through the knob and connected to break the toggle lock formed by said catches.
In testimony whereof I afHx my signature.
