Mitsubishi Buttons MTD180 BA180 BA181

Mitsubishi Buttons MTD180 / BA180 / BA181 are used in Mitsubishi elevator operating panel and call button applications.

These buttons are commonly requested for elevator COP, LOP, hall call panel, landing call panel, or elevator button replacement work. In the elevator spare parts market, they may also be searched as:

• Mitsubishi Elevator Button
• Mitsubishi Elevator Push Button
• Mitsubishi MTD180 Button
• Mitsubishi BA180 Button
• Mitsubishi BA181 Button
• Mitsubishi DA180 Button
• Mitsubishi COP Button
• Mitsubishi LOP Button
• Mitsubishi Hall Call Button

The main model references for this page are:

• MTD180
• BA180
• BA181

Related model reference:

• DA180

These model names often appear together in elevator button listings. However, the final replacement should still be confirmed by the old button label, button size, rear structure, voltage, illumination style, and panel installation position.

Button Application

MTD180 / BA180 / BA181 should be understood as Mitsubishi elevator push button models, not button expansion boards or display boards.

Depending on the original elevator configuration, these buttons may be used in:

• car operating panel
• landing operating panel
• hall call panel
• outbound call panel
• elevator button panel
• maintenance replacement button assembly

A button installed inside the elevator car and a button installed on the landing side may look similar from the front, but the rear connector, lamp structure, mounting clip, button depth, and panel opening size may be different.

For this reason, MTD180 / BA180 / BA181 should not be selected only by front appearance.

Model and Physical Confirmation

Before ordering Mitsubishi Buttons MTD180 / BA180 / BA181, please confirm:

• complete model number on the old button
• whether the old part shows MTD180, BA180, BA181, or DA180
• front photo of the button
• back photo of the button module
• connector or terminal structure
• button size and mounting method
• working voltage if shown on the label
• illumination color if available
• whether it is used in COP, LOP, or hall call panel
• complete panel photo showing the installation position

This information helps confirm whether the required item is a car operating panel button, 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 designs, but the rear structure can be different. A similar-looking button may use a different connector, lamp type, mounting clip, or wiring method.

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 problem may come from the LED or lamp circuit, the button module itself, the COP / LOP board, or the panel wiring.

For overseas buyers, sending clear photos of the old MTD180 / BA180 / BA181 button from both front and back sides is the safest way to confirm the correct replacement before shipment.
