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
