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.,

used master appliances. The collision produced by moving mechanical parts which contact to move on or off control circuit, to control the

reverse movement, variable motion or automatic reciprocating movement. In the electrical control system, the limit switch is

?墻之外，目不見也；里之前，耳不聞也；而人主之守司，遠(yuǎn)者天下，近者境內(nèi)， 不可不略知也。天下之變，境內(nèi)之事，有弛易齵差者矣，而人主無由知之，則是拘 脅蔽塞之端也。耳目之明，如是其狹也；人主之守司，如是其廣也；其中不可以不 知也，如是其危也。然則人主將何以知之？曰：便嬖左右者，人主之所以窺遠(yuǎn)收眾 之門戶牖向也，不可不早具也。故人主必將有便嬖左右足信者，然后可。其知惠足 使規(guī)物，其端誠足使定物，然后可；夫是之謂國具。人主不能不有游觀安燕之時， 則不得不有疾病物故之變焉。如是，國者，事物之至也如泉原，一物不應(yīng)，亂之端 也。故曰：人主不可以獨也。卿相輔佐，人主之基杖也，不可不早具也。故人主必 將有卿相輔佐足任者，然后可。其德音足以填撫百姓，其知慮足以應(yīng)待萬變，然后 可；夫是之謂國具。四鄰諸侯之相與，不可以不相接也，然而不必相親也，故人主 必將有足使喻志決疑于遠(yuǎn)方者，然后可。其辯說足以解煩，其知慮足以決疑，其齊 斷足以距難，不還秩，不反君，然而應(yīng)薄捍患，足以持社稷，然后可，夫是之謂國 具。故人主無便嬖左右足信者，謂之闇；無卿相輔佐足任使者，謂之獨；所使于四 鄰諸侯者非其人，謂之孤；孤獨而晻，謂之危。國雖若存，古之人曰亡矣。詩曰： “濟濟多士，文王以寧。”此之謂也。
