Frame 31 and can movable contact spring 33 composition the part of microswitch component 3 in structure without fixed-direction；It is described overall, spacing in brush nest
Control-rod and microswitch are limited without fixed structure and form.
Further, break-make brush nest outside is equipped with or is not equipped with or section components outside is equipped with shell.
The present invention is in assembling design：Spacing control-rod can be arranged on any carbon brush operation face of brush nest, and during design
There is no the limitation of fixed-direction.The driving force for being applied to spacing control-rod is pressure or pulling force.Brush nest, spacing control drivetrain
Unite, microswitch system is made of one, or be separated into single part and be finally installed together.
Operation principle of the invention is：Carbon brush power supply is connected on switch bracket, carbon brush is put into carbon brush supports, because of carbon
The support force of brush just pushes up out spacing control-rod, spacing control more than control-rod torsion spring or the active force of control-rod stage clip, then carbon brush
Bar processed releases dynamic support after being pushed up out, and dynamic support then release act on movable contact spring can movable contact spring deformation force, move and touch
Piece contact turns on fixed touching plate contact, machine energization work, and with the operation of a machine, constantly friction disappears between rotor and carbon brush
Consumption, rubs due to acting on the axle spring on carbon brush or disc spring pressure more than the radial direction that control-rod extension spring or stage clip are applied to carbon brush
Wipe power so that carbon brush constantly moves forward in the consumption that rubs, and when finally moving forward to extreme position because of abrasion, spacing control-rod loses carbon
Brush support force, due to the extension spring power or pressure spring force suffered by control-rod more than can movable contact spring deformation force, therefore once spacing control-rod
Carbon brush support force is lost, control-rod will inwards promote dynamic support, movable contact spring is promoted after dynamic support force, forcing can movable contact spring change
Shape cuts off carbon brush power supply to drive movable contact spring to break through zero boundary position of switch.
It is preferred that it is mounted with the spacing control that can be switched over to microswitch break-make on any carbon brush operation face of brush nest
Bar processed, microswitch is controlled by spacing control-rod, then the power supply of carbon brush is switched on or switched off by microswitch, spacing control-rod
Power comes from carbon brush from the spring force suffered by control-rod, the support force of spacing control-rod.It can be in carbon brush abrasion to the limit
When cut-out carbon brush power supply, change after traditional carbon brush for electric machine abrasion surmounts certain limit, copper conductor head in carbon brush or
Compression spring will directly touch with rotor commutator so that burn out commutator surface situation, before solving in technology not
The key issue that can be promoted, the loose contact phenomenon under critical condition reduces the economic loss of user, saves resource；
Overall structure is simply compact, practical, it is easy to promote the use of.
