These model references are useful for product search and quotation confirmation. However, different G versions should still be checked against the original button label, rear structure, connector type, illumination style, and panel installation position before replacement.

Lift Call Button Application

This product should be understood as an elevator call button or operating panel button, not a PCB expansion board.

Depending on the original elevator configuration, it may be installed in:

• landing operating panel
• hall call panel
• outbound call panel
• elevator button panel
• car operating panel in some configurations

A landing call button and a car operating panel button may look similar from the front, but the rear mounting structure, wiring terminal, button depth, lamp type, and panel opening size may be different.

For this reason, ZLHB-LAK1 / ZLHB-LAO1 should not be selected only by front appearance.

What Buyers Should Confirm

Before ordering Mitsubishi Button ZLHB-LAK1 / ZLHB-LAO1 / P235097B187G01, please check:

• complete model number on the old button
• whether the old button shows ZLHB-LAK1 or ZLHB-LAO1
• whether the old label shows G01, G02, G05, or G06
• front photo of the button
• back photo of the button module
• connector or terminal photo
• button size and mounting structure
• illumination color if available
• whether it is used in LOP, HOP, hall call panel, or COP
• complete panel photo showing the installation position

This information helps confirm whether the required part is a landing call button, hall call button, or another Mitsubishi elevator push button version.

Practical Replacement Notes

Do not replace this button only by the front style.

Mitsubishi elevator buttons may have similar faceplate design, but the rear structure can be different. A similar-looking button may use a different connector, lamp structure, mounting clip, or signal wiring.

If the button does not respond, technicians usually check the button contact, wiring harness, connector terminals, button board, and related signal circuit before confirming the button fault.

If the button light does not work, the cause may come from the LED or lamp circuit, the button module itself, the LOP / HOP board, or the panel wiring.

For overseas buyers, sending clear photos of the old ZLHB-LAK1 / ZLHB-LAO1 button from both front and back sides is the safest way to confirm the correct replacement before shipment.
