Definitions
- the invention relates to a push-pull switch an actuating mechanism that has a handle, one with the handle related actuating plunger Actuation of a switching element and a rosette, in which the actuating plunger is axially displaceable, wherein the actuating plunger has a locking element which at Engage the ON actuation on the rosette.
- a generic push-pull switch has been on the for years Electronics market delivered.
- the system used here works with detents in the axial direction, i.e. in the direction of the switching element paths two or more stationary positions enable the handle.
- Those used here as locking elements Balls move between the ON and OFF positions back and forth in the same way.
- the balls snap spring-loaded from a valley in the ON position over a mountain in a valley behind it for the AUS position and on the same Way back.
- the holding force of the detent reduced by the restoring forces of the actuated switching elements. Therefore there must be a sufficiently large difference between the one actually required for snapping back Force and the sum of the maximum restoring forces that occur of the switching elements can be ensured.
- the resetting force is oversized, causing the material is under constant stress. Hence the lifespan is limited and the ease of use due to the extremely hard detent reduced.
- the invention is therefore based on the object of a push-pull switch of the type mentioned above for electromechanical control devices to create that of the contact pressure of the actuated Switching elements can not be reset and a maximum offers functional reliability and ease of use.
- the object is achieved in that the actuating plunger is engaged with a thread in the handle, whereby a pulling motion on the handle into a rotary motion of the Actuating plunger is convertible to release the locking.
- This solution according to the invention makes it possible in principle for the ON and OFF switching process other ways for the Provide locking elements to ensure a safe, avoiding resetting To ensure locking in the ON position.
- the mentioned solution also has the advantage that no additional Part for turning unlocking is required.
- a particularly advantageous embodiment is when the Rosette a tangentially extending and tapering Has recess in which in the ON position designed as balls Locking elements are included.
- This version enables the rotary release, in which the actuating plunger is rotated is and thereby the locking elements on the contour of Recess gently and in their starting position, i.e. the OFF position.
- the balls are in the ON position more than half their diameter in the recess are. Even strong blows and vibrations combined with large restoring forces of the actuated switching elements do not lead to resets with such an execution.
- FIGs 1, 2 show a sectional view of an inventive Actuation mechanism 1 of a push-pull switch.
- the actuating mechanism 1 is in the starting position "OFF" shown.
- the operating mechanism 1 comprises a handle 2, one associated with this Actuating plunger 3 for actuating a switching element and a cylindrical rosette 4.
- the handle 2 with the actuating plunger 3 is in the direction of actuation according to arrow 5 axially displaceable.
- the actuating plunger 3 is with spring-loaded balls 6 provided as locking elements, the in the OFF position according to FIG. 1 in an upper recess 7 grasp the inner wall of the rosette 4.
- the balls 6 lie on a slope 8 of a projection 9, which is down another recess 10 connects.
- the transition of the lead 9 in the further recess 10 is perpendicular to.
- the further recess 10 serves as a rest valley, in which the balls 6 when the Lock handle 2 and thus the actuating plunger 3 in the Hold the ON position as shown in Figures 2 and 3.
- the recess 10 extends tangentially on the inner circumference of the rosette 4 a taper according to Figure 4.
- the handle 2 is with a Steep thread 11 provided with which the actuating plunger 3 in Intervention stands.
- a compression spring 12 is with its lower End on the rosette 4 and with its upper end on the actuating plunger 3 supported.
