An object of the present invention is to minimize the lateral width between the respective parts is provided and coupled relates to a coupling structure of the lift switch, a predetermined area in the direction of the internal geometry of the switch structure of the switch to produce small.
According to a preferred embodiment of the present invention to achieve the above object, a frame, a press plate for vertical movement along the inner side of the frame and coupled to a lower portion of the frame, including the circuit board that is formed by Detect Switch Configuration in the coupling structure of the elevator switches, wherein the frame is made up of a cylindrical inner side of the bridge-shaped guide ring is formed, it is formed a bottom bracket of the bridge-type of the guide ring, wherein the bracket has a through-hole is formed of a columnar the actuator is inserted, the push plate is at predetermined intervals on a lower surface formed with a plurality of protrusions are inserted into the inside of the guide ring, wherein between each projection being formed a plurality of engaging grooves, and the engaging groove has a buffer member is been coupled to the through-holes located in the upper portion of the bracket, in conjunction with the external force acting on the pressure plate and to the technical aspect that the actuator for lowering.
The present invention consisting of a coupling structure as described above will operate the actuator, the actuator of the columnar to the bracket of the bridge type formed in a guide ring at the bottom of the frame and to be inserted in the longitudinal direction, via a buffering member coupled to the protruding portion of the pressing plate thereby, a horizontal width that is coupled between the parts is minimized, it is possible to create a compact switch structure.
Therefore, it can be attached to the elevator that require the switch structure of the compact has the advantage of being able to respond to different customer needs.
