Abstract

The utility model relates to a magnetic suspension type switch. A switch button of the magnetic suspension type switch is fixed inside a switch box by a rotary shaft, wherein, the bottom of the button is inlaid with a magnet, and both sides of the button are fixed with contact plates; the bottom of the switch box just under the button is provided with a magnet, and the opposite surfaces of the two magnets have the same polarity. Binding posts are arranged on both sides of a shell body of the switch box, and the positions of the binding posts correspond to the button contact plates. The utility model is made according to the magnetic suspension principle, and the two magnets do not contact each other so as to prevent fatigue wear of an elastic switch when the elastic switch is used. Compared with the existing switches, the utility model has the advantages of flexible opening and closing, stable performance, high safety, simple manufacture technology, long service life, etc.

Description

The electromagnetic levitation type switch

The utility model belongs to the low-voltage electrical apparatus switch, is specifically related to a kind of electromagnetic levitation type switch.

Existing low-voltage electrical apparatus switch mainly is the disconnection and the break-make that resets control circuit by the contact reed, increase along with access times, can occur inevitably that plastic clip fractures, steel ball goes out phenomenons such as position, the top wearing and tearing of plastics, cause the reed loose contact, malfunctioning switch also can bring some potential safety hazards sometimes.

The purpose of this utility model provides long electromagnetic levitation type switch of a kind of simple in structure, highly sensitive, safe and reliable, life-span.

Technical solution of the present utility model is: shift knob is fixed in the switch enclosure by a rotating shaft, and the button bottom is embedded with magnet, and both sides are fixed with touch panel; Magnet is equipped with in switch enclosure bottom under the button, and the polarity of above-mentioned two magnet opposite faces is identical; Binding post is contained in switch enclosure housing both sides, and its position is corresponding with the button touch panel.

During use, because the button bottom is identical with the polarity of two magnet opposite faces of switch enclosure bottom setting, repulsive force maximum when two magnet positions are relative, thrust is zero partially.When artificial touch switch button, button can center on the reciprocal deflection of rotating shaft, and two magnet center change, and repulsive force becomes inclined to one side thrust, impels button amesiality, and touch panel and left and right sides binding post are switched on or switched off, thereby reaches the connecting and disconnecting of control circuit.

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is an electromagnetic levitation type push-button switch structure schematic diagram;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 falls along push-button switch for the electromagnetic levitation type three-phase;

Fig. 4 is the vertical view of Fig. 3.

Wherein: 1, magnet 6, binding post 7, switch enclosure housing at the bottom of button 2, rotating shaft 3, button magnet 4, touch panel 5, the box

As shown in Figure 1 and Figure 2, button 1 is supported on switch enclosure housing 7 centers by rotating shaft 2, is embedded with magnet 3 in the bottom of button, and touch panel 4 is arranged on the button both sides, and binding post 6 is positioned at switch enclosure housing both sides, and the position is corresponding with touch panel; Switch enclosure housing bottom under button is equipped with magnet 5, and magnet 5 is identical with the magnetic pole of magnet 3 opposite faces.

According to design of the present utility model, above-mentioned electromagnetic levitation type switch can also be made as three-phase and fall along push-button switch, as shown in Figure 3, Figure 4.The binding post 6 of switch enclosure housing 7 both sides is set to two-layer up and down, and every layer is three binding posts, and the touch panel on the button 4 is divided into three sections, and the touch panel position that is fixed on the button both sides is corresponding with binding post.The conversion order of connection, the break-make of may command three-phase circuit.

The utility model utilizes magnetic suspension principle to make, because two magnets do not contact mutually, has avoided elasticity to open Fatigue wear when close using is compared with existing switch, have open and close flexibly, stable performance, safety can The characteristics such as, long service life simple by, manufacture craft.
