AusProduce.Under the situation of coupling auxiliary switch HS, disconnect required power corresponding to additional elastic force F
HSIncrease.Disconnecting needed bimetal leaf under the thermal overload situation must be according to certain path deflection.To have an opposite force to be applied on the bimetal leaf by trip lever 7, this power reduces the deflection of bimetal leaf corresponding to its intrinsic elastic force.Therefore the deflection that disconnects required bimetal leaf can only just realize under higher thermal overload.
If power switch neither one auxiliary switch then only has to discharge required elastic force F as shown in Figure 6
AusWork.The influence of the intrinsic elastic force of bimetal leaf as a result is less, discharges in advance to realize beyond the tolerance of regulation.Therefore when equipment calibration, must consider to set up auxiliary switch.The range of tolerable variance that allows will need owing to the power of auxiliary switch to reduce, and cause the increase of manufacturing cost.
The thermal cutoff device is complementary according to its intrinsic elastic force and release force, makes power switch discharge in predetermined scope and shutoff.Cut off value should be abideed by the tolerance of determining according to the rules.This point is achieved in that to be the level that auxiliary switch is maintained at a low power up to now.Wherein use low contact pressure and finish the work than the auxiliary switch of peanut.
The objective of the invention is to, to a kind of power switch proposition improvement that has couplable secondary switch of aforementioned type, to avoid of the influence of the additional auxiliary switch that is coupled the cut off value of less cost.
The object of the present invention is achieved like this, a kind of power switch that has the auxiliary switch that can be coupled promptly is provided, wherein power switch has a switch lockout device that has switch shaft or switch slide block, the auxiliary contact of the main contacts of power switch and auxiliary power switch can be controlled by this switch shaft or switch slide block, on-state at power switch, auxiliary switch does not exist with switch shaft and is connected, when the off status of power switch changed, switch shaft caused the transformation of the on off state of auxiliary switch after overcoming pre-allowance.
Particularly advantageous execution mode of the present invention is as follows, and a pre-allowance is set between switch shaft and lever, this lever with a rotatably support and the rocking bar that is used to control the main contacts break-make be connected effectively.
Slide block preferably is connected effectively with the bridge bracket that touches of auxiliary switch.
