KONE TR236-11 Roller Lever Limit Switch

KONE TR236-11 is a mechanical roller lever limit switch used in compatible KONE elevator systems for position monitoring and safety control.

The switch operates through a roller lever actuator. When the moving component reaches the preset position, the roller activates the internal contacts and sends the corresponding control signal to the elevator system.

Depending on the installation, this product may also be identified as:

• KONE TR236-11

• KONE T1R236-11

• KONE T1R236-11Z

• KONE Roller Lever Limit Switch

• KONE Position Limit Switch

• KONE Mechanical Limit Switch

• KONE Travel Limit Switch

• Elevator Roller Limit Switch

KONE officially supplies this type of switch as a 1NO + 1NC roller lever limit switch with a rated voltage of 230V and rated current of 4A.

Confirm the Actuator Before Ordering

Although many elevator limit switches look similar externally, differences in the roller arm, contact configuration, mounting holes, and cable entry may prevent direct replacement.

Before requesting a quotation, please provide:

• TR236-11 or T1R236-11 model marking

• complete product label

• roller lever type

• contact configuration

• mounting-hole spacing

• cable entry direction

• connector or terminal style

• installation position

• front and side photographs

• quantity required

A complete photo of the installed switch is usually more useful than the switch body alone because it helps confirm the actuator direction and mounting arrangement.

Mechanical Adjustment Is Important

A limit switch may appear defective even when the internal contacts remain functional.

Before replacing the switch, technicians should also inspect:

• roller condition

• lever movement

• mounting bracket

• actuator alignment

• mechanical stop position

• cable condition

• terminal connections

• surrounding linkage

Improper adjustment or a bent actuator may prevent the switch from operating correctly even after installing a new unit.

After replacement, the switch should be adjusted according to the original operating position and verified through functional testing by qualified elevator technicians.

For maintenance companies in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain, and Italy, clear photos of the complete switch, actuator, mounting position, and wiring are recommended before shipment.

FAQ

Is TR236-11 a standard microswitch?

No. It is a mechanical roller lever limit switch designed for position sensing rather than a standard panel microswitch.

What contact configuration does it use?

The KONE version is commonly supplied with 1 Normally Open (NO) and 1 Normally Closed (NC) contact arrangement.

Can another TR236 switch replace it?

Not automatically. The actuator type, lever direction, mounting dimensions, contact configuration, and wiring should all match the original switch.

What information should I send before ordering?

Please provide the complete model label, photos from multiple angles, installation position, roller lever details, terminal arrangement, and overall dimensions.
