Abstract
The utility model relates to a switch, more specifically a magnetic approach travel switch, which is provided with a travel switch, a switch casing, a casing cover, NS magnetic steel, etc., wherein the inner side of the switch casing is also provided with a rotary shaft slurcock; the inner side of the rotary shaft slurcock is provided with a short magnetic plate; the NS magnetic steel is inserted into the rotary shaft slurcock; the short magnetic plate is arranged at the bottom of the NS magnetic steel. The utility model has the advantages of reasonable design, simple structure, small size, low cost and long service life, and is suitable for various limit switches and terminal travel switches.
Description
Technical field:
The utility model relates to a kind of switch, and specifically a kind of magnetic is near travel switch.
Background technology:
According to the knowledge of the applicant, travel switch in the market is of a great variety, as the straight-bar roller type, and single both arms roller type and universal type etc.But they exist many weak points, complex structure; The cost height; The rocker-arm roller of travel switch, straight-bar all are unable to undergo frequent collision impact, cause mechanical damage, reduce the life-span of switch.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provides a kind of simple in structure, and volume is little, and the magnetic of mechanical parts such as no straight-bar and roller rock arm is near travel switch.
The technical scheme that its technical problem that solves the utility model adopts is that a kind of magnetic is near travel switch, it is provided with travel switch, switch case, case lid, NS magnet steel, it is characterized in that also being provided with in the housing rotating shaft slurcam, be provided with short magnetic sheet in the rotating shaft slurcam, the NS magnet steel is embedded in the slurcam, and short magnetic sheet is positioned at the bottom of NS magnet steel.
The utility model is reasonable in design, and is simple in structure, and volume is little, do not have mechanical structure, and easy to use, the life-span is long, and cost is low, is suitable for various limit switches and terminal travel switch and uses.
Description of drawings:
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As can be seen from Figure 1, a kind of magnetic of the utility model comprises switch case 1, travel switch 2, case lid 3, rotating shaft slurcam 4, NS magnet steel 5 and short magnetic sheet 6 near travel switch.Wherein, switch case 1, travel switch 2, case lid 3 are prior art, and this does not describe in detail.The utility model switch case 1 can be moulded aluminium near housing by what plastic material or aluminium type material processed, so that NS magnet steel magnetic force effectively passes switch case adhesive external metallization iron plate.Also be provided with rotating shaft slurcam 4 in the housing 1.NS magnet steel 5 is embedded in the rotating shaft slurcam 4.The bottom of NS magnet steel 5 is provided with short magnetic sheet 6 in the rotating shaft slurcam 4, and to change the magnetic circuit of magnet steel, controlling magnetic field suction is limited to top work.During the utility model work, when the spacing monolithic metal in outside near NS magnet steel housing, magnetic force quick pick-up limiting plate drives the rotating shaft slurcam and rotates, forward another angle to by an angle, promote travel switch disjunction closing contact, finish the travel switch on-off circuit, realize the spacing electric function of control.
The utility model is reasonable in design, and is simple in structure, and volume is little, do not have mechanical structure, and cost is low, and is easy to use, and the life-span is long, and cost is low, is suitable for various limit switches and terminal travel switch and uses.
