Mitsubishi Elevator Button C5MS1PW12D / C5MS1W12D / C5MS1B12D / KANJ1810B is used in Mitsubishi elevator hall operating panel and landing operating panel button applications.

These references are useful for search coverage and quotation confirmation. However, the final replacement should still be confirmed by the old button label, rear structure, connector type, illumination style, and panel installation position.

HOP and LOP Button Application

This button should be understood as a Mitsubishi elevator call button series, not a button expansion board or display PCB.

It is more commonly associated with landing-side applications such as:

• hall operating panel
• landing operating panel
• hall call panel
• outbound call panel
• elevator floor call button
• elevator push button replacement

Depending on the elevator configuration, a similar-looking button may also appear in other operating panel areas. For this reason, the old button and full panel should be checked before replacement.

Model and Rear Structure Confirmation

C5MS1PW12D / C5MS1W12D / C5MS1B12D should not be selected only by the front appearance.

Before ordering, please confirm:

• complete model number on the old button
• whether the old part shows C5MS1PW12D, C5MS1W12D, C5MS1B12D, or KANJ1810B
• whether the model is written with hyphen, such as C5MS-1W12D
• front photo of the button
• back photo of the button module
• connector or terminal structure
• button size and mounting style
• illumination color if available
• whether it is used in HOP, LOP, or hall call panel
• complete panel photo showing the installation position

This information helps avoid ordering a button with a similar faceplate but a different rear connector, lamp structure, or mounting method.

Practical Replacement Notes

Do not replace this button only by the model family name.

C5MS and KAN-J1810B references may appear together in market listings, but the exact old button structure should still be checked before shipment. A small difference in rear connector, mounting clip, lighting method, or panel opening size may affect installation.

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 HOP / LOP board, or the landing panel wiring.

For overseas buyers, sending clear front and back photos of the old C5MS1PW12D / C5MS1W12D / C5MS1B12D / KANJ1810B button is the safest way to confirm the correct replacement before shipment.
