Limit Switch 236-ZR11 / 236-TR11

Limit Switch 236-ZR11 / 236-TR11 is used in elevator shaft signal, travel limit, buffer area, and safety position detection applications.

This switch may be installed in the hoistway, pit, buffer area, terminal limit position, or other elevator safety signal locations, depending on the original elevator system design. In maintenance replacement, it should be checked by the old switch model, reset type, actuator structure, contact logic, terminal layout, and mounting position.

ZR11 and TR11 should be checked carefully before ordering. In some market references, ZR11 and TR11 may relate to different reset styles or switch versions. They should not be treated as the same part only because the model numbers look close.

For replacement, buyers should confirm:

• complete model number on the old switch

• whether the old part shows 236-ZR11 or 236-TR11

• manual reset or automatic reset type

• actuator style, roller, lever, or plunger structure

• contact type if marked

• terminal layout and wiring direction

• mounting hole position

• bracket or installation base

• installed position in the shaft, pit, or buffer area

• old switch label, side view, terminal, and installed photos

This switch may be replaced when the elevator has limit signal failure, buffer switch fault, terminal position error, safety circuit interruption, damaged actuator, poor contact, broken terminal, or abnormal reset condition. These problems may also come from wiring, controller input, bracket misalignment, cam position, buffer structure, or previous adjustment work.

For buyers in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Chile, Spain, and Italy, clear old-switch photos and wiring photos are recommended before shipment. If the switch is ordered together with other elevator shaft parts, safety switches, sensors, buffers, or XIOLIFT elevator spare parts, the reset type and installation structure should be confirmed before packing.

FAQ

Are 236-ZR11 and 236-TR11 the same switch?

Not necessarily. They may appear together in product listings, but the reset type, actuator structure, or contact arrangement may be different. Please confirm the old switch label and photos before ordering.

What is the most important detail to check?

The model marking, reset type, actuator shape, terminal layout, and mounting position are the most important details.

Can I order only by the model number?

The model number is useful, but photo confirmation is recommended because similar elevator limit switches may have different reset structures or installation brackets.
