The limit switch is used to switch the electrical machinery movement limit position limit.
?
?
Limit switch contact type and non-contact. Contact directly, moving parts of machinery and equipment, installed on the trip switch, fixed
?
?
point and its relative motion is arranged on the limit position of the block, or the opposite position. When the mechanical contact travel switch
?
?
with stop, cut off (or change) control circuit, mechanical stop operation or change operation. Due to the inertia motion, the travel switch "
?
?
over travel" to protect certain switch from damage. A lot of non contact form, there is a common reed, photoelectric induction type, etc.,
?
?
?these several forms can be seen in the elevator. There are certainly more advanced form. The limit switch is a small current commonly
?
?
used master appliances. The collision produced by moving mechanical parts which contact to move on or off control circuit, to control the

?
?purpose of. Usually, this kind of switch is used to limit the movement of the mechanical position or stroke, the mechanical movement according to a certain position or stroke automatic stop,
?
?
reverse movement, variable motion or automatic reciprocating movement. In the electrical control system, the limit switch is
?
?
?the role of detection of sequence control,

道者，何也？曰：君之所道也。君者，何也？曰：能群也。能群也者，何也？ 曰：善生養(yǎng)人者也，善班治人者也，善顯設(shè)人者也，善藩飾人者也。善生養(yǎng)人者人 親之，善班治人者人安之，善顯設(shè)人者人樂之，善藩飾人者人榮之。四統(tǒng)者俱，而 天下歸之，夫是之謂能群。不能生養(yǎng)人者，人不親也；不能班治人者，人不安也； 不能顯設(shè)人者，人不樂也；不能藩飾人者，人不榮也。四統(tǒng)者亡，而天下去之，夫 是之謂匹夫。故曰：道存則國存，道亡則國亡。省工賈，眾農(nóng)夫，禁盜賊，除奸邪： 是所以生養(yǎng)之也。天子三公，諸侯一相，大夫擅官，士保職，莫不法度而公：是所 以班治之也。論德而定次，量能而授官，皆使人載其事，而各得其所宜，上賢使之 為三公，次賢使之為諸侯，下賢使之為士大夫：是所以顯設(shè)之也。修冠弁衣裳，黼 黻文章，琱琢刻鏤，皆有等差：是所以藩飾之也。故由天子至于庶人也，莫不騁其 能，得其志，安樂其事，是所同也；衣暖而食充，居安而游樂，事時制明而用足， 是又所同也。若夫重色而成文章，重味而成珍備，是所衍也。圣王財衍，以明辨異， 上以飾賢良而明貴賤，下以飾長幼而明親疏。上在王公之朝，下在百姓之家，天下 曉然皆知其所以為異也，將以明分達(dá)治而保萬世也。故天子諸侯無靡費(fèi)之用，士大 夫無流淫之行，百吏官人無怠慢之事，眾庶百姓無奸怪之俗，無盜賊之罪，其能以 稱義遍矣。故曰：治則衍及百姓，亂則不足及王公。此之謂也。
