KONE Elevator Limit Switch JY-TV336-11Z KM50307576G01

The KONE JY-TV336-11Z limit switch, referenced as KM50307576G01, is used as a mechanical position switch in compatible KONE elevator equipment. It converts mechanical movement into an electrical signal when a moving component reaches its preset position.

Unlike electronic sensors, this type of switch is identified mainly by its actuator style, contact arrangement, mounting dimensions, and cable-entry direction. These details are usually more important than the housing appearance.

Before Ordering, Compare the Installed Switch

Many maintenance companies receive a switch with a similar body but different lever or roller configuration. A quick comparison before ordering can prevent unnecessary replacement.

Please check the following:

• Model marking: JY-TV336-11Z

• Part number: KM50307576G01

• Roller or actuator type

• Lever direction

• Mounting-hole spacing

• Terminal configuration

• Cable-entry position

• Overall dimensions

• Photos of the installed switch

The switch may be replaced when the contacts fail to change state consistently, the roller mechanism becomes worn, the actuator sticks, or the housing is physically damaged. During inspection, technicians should also verify that the mounting bracket, moving cam, wiring terminals, and switch alignment remain in good condition.

If possible, send several photos of the original switch from different angles together with the part number label. This makes it much easier to confirm the correct configuration before shipment.

We regularly supply this model to elevator service companies in Saudi Arabia, Jordan, Egypt, Iraq, the UAE, Brazil, Chile, Spain, and Italy, where accurate identification before dispatch helps reduce installation delays.
