1.In close to the magnetic contact switch is used to make the field, if there magnet around, it will lower the effective magnetic field, change operation characteristics, therefore, the switching around, not a strong magnetic field, 100mm allowed in any other magnet. Ver.2 use two or more switches, in order to avoid the influence each other. Please use the following methods to install the first method to install one, This examination will be greater than two times the relative distance from the most important action switches (shown in the figure) N 2 using magnets with its second approach when installing another body to the S pole more than 2 times the relative distance from the switch. MAGNET'S MAGNET'S very highly with another more than four times the relative distance to the switch biggest move distance 3) Contact the use of correct order, Contact with the previous corresponding to the magnetic polarity of the same magnet. as shown in figure
4) electricity magnets connection electricity magnet storage battery of current supply power source
available or power source, may prepare special use power facility according to switch sigmatism
quantity, if use a switch only, two line of electricity magnet is not bad at will meet all above is
to prevent nns or snn from influencing each other , to ask to ensure that electricity magnet
magnetic field is when working a telephone switchboard in power source both ends, with two when the
switch,
5> touches power source and loads linking up including 1 line exposed two
terminals cascade , may link loads directly when exceed fixed value 2 as if it
be loads if within fixed load, should adopt the centre relay buffered, by the
fact that increasingly, centre relay Russia electric current small , opening

MAGNET'S MAGNET'S very highly with another more than four times the relative distance to the switch biggest move distance 3) Contact the use of correct order, Contact with the previous corresponding to the magnetic polarity of the same magnet. as shown in figure 4) The wiring electromagnetic body's electromagnetic power supply or battery power available. ready to be used in accordance with the exclusive power switching equipment, if the use of a switch, The two of electromagnetic power lines can arbitrarily privilege ends with two or more switch, to prevent the mutual influence, Connection to the electro-magnetic field to ensure snn ＜ 5 ＞ Contact nns or she is the one link connecting two of wiring power supply terminal and load Series, If the rated load, the load may be a direct link between the two rating when the load exceeds that should be intermediate relay buffer Current Russian intermediate relay through smaller, the longer the life expectancy of three switches off when Contact Contact inductive load, surge voltage and current to absorb shocks. Please parallel RC circuit with four load sensors exist for cable distribution and storage capacitor charge, then took action, impact of the discharge current form, easily Burning connections, wiring should be as brief as possible, limited to 20 meters, If wiring more than 20 meters, the need to follow a series of impact resistance and protect connections, and another, Wiring should try to stay away from other wiring.

1> The magnetism approaches the switch is causes the contact workusing the magnetic field, if periphery has the magnet, can reduce theeffective magnetic field, the change movement characteristic,therefore, around the switch, must not have the strong magnetic field,must not have other magnets in 100mm. When 2 > uses two above switches, avoids the mutual influence, pleaseuse as follows installs the method 1 uses when the first method installs, this physicalexamination relative spacing must be bigger than 2 time of switchesbiggest movements to be away from (like chart to show) 2 uses the second method installs when magnet N extremely withanother body S interelectrode relative spacing to have to be biggerthan 2 time of switches movements distance, magnet S extremely withanother magnet S extremely relative spacing must be bigger than 4 timeof switches maximum movements distance When 3) the contact enemy arranges the use, the contactcorresponds the magnet should be same with the preceding magnetpolarity, like the chart shows 4) 电磁体 wiring 电磁体 the electric power supply may use the storage batteryor the power source, may act according to the switch the use quantitypreparation special-purpose power equipment, if only uses a switch,电磁体 two lines may meet at will in the power source beginningsand ends, when with two above switches, is prevented mutually affects,when wiring must guarantee 电磁体 the magnetic field is nns or snn 5> Contact segment 1 raises one's head two terminals series connection powersource and the load, like in the rated load, may directly connect theload 2 when the load surpasses the rated value, should use theintermediate relay cushion, passes the intermediate relay Russiaelectric current smaller, the switch life is longer 3 when the contact contact passes breaks the perceptual load,is the absorption surge current and the surge voltage, please withinduction load parallel RC absorbing circuit 4 when saves the electric charge because of the wire existencedistributed capacity, the contact movement, forms the impactdischarging current, easy fever melt contact, therefore the wiringshould be as far as possible short, limits in 20 meters, if the wiringsurpasses 20 meters, must meet a anti- impact the series resistance,protects the contact, moreover, the wiring must be far away other tomatch the line as far as possible.
