The utility model content

The designer is in the practice of daily use appliance switch, find that the prior mechanical switch exists certain defective, through investigation, update, purpose be to provide a kind of multi-functional wink the consumption mechanical switch, only instantaneous power consumption when switch state, and power supply have a power failure or and the power supply superpressure, the load superpressure can automatically shut down under the load overcurrent condition.

Technical solution adopted in the utility model is a kind of multi-functional wink of design to consume mechanical switch, its structure comprises: mechanical switch, DC power supply is set in housing, control circuit, automatically controlled port, manual switch, actuation coil, action armature, the power failure breaking circuit links to each other with control circuit, wherein DC power supply links to each other with control circuit, automatically controlled port, manual switch links to each other with control circuit respectively, and actuation coil links to each other with control circuit, action armature is controlled by actuation coil magnetic field, action armature links to each other with the mechanical switch moving part, realizes automatically controlled, manual control, wink is consumed, have a power failure and turn-off.

In order to enlarge the function of mechanical switch; the utility model also in said structure, add connect power supply superpressure limit open circuit or and load superpressure breaking circuit; the overcurrent breaking circuit; wherein power supply superpressure limit open circuit links to each other with DC power supply; power supply superpressure limit open circuit, load superpressure breaking circuit, overcurrent breaking circuit all link to each other with control circuit; load superpressure breaking circuit is in parallel with load; the overcurrent breaking circuit is connected with load; refuse out the defencive function that when load superpressure and load overcurrent, automatically shuts down when being implemented in supply voltage superpressure situation.

The utility model adopts technique scheme and measure, the prior mechanical switch is improved, mechanical switch combines with DC power supply, control circuit, automatically controlled port, manual switch, actuation coil, action armature and power failure breaking circuit, loss little electrical energy when each state exchange only, opening or turn-offing not power consumption in the stable state, when producing an automatically controlled signal, the back power failure breaking circuit that has a power failure utilize energy storage that mechanical switch is turn-offed, in case the mistiming that restores electricity is started shooting.Increase power supply superpressure limit open circuit or and load superpressure breaking circuit, behind the overcurrent breaking circuit, superpressure limit open circuit energy short circuit input current when the power supply superpressure, play superpressure and refuse out effect, the superpressure breaking circuit can play the effect that mechanical switch is changed into off state by opening when the load superpressure, after load current was greater than the permission electric current of setting, the overcurrent breaking circuit can produce an automatically controlled electric current power cutoff.

This multi-functional wink of the present utility model is consumed mechanical switch, has overcome the shortcoming of existing machinery formula switch and electronic switch, collects the advantage of the two, will be used widely in modern electrical equipment.
