Mitsubishi Push-Button Expansion Board P235709B000G01 is used in Mitsubishi elevator car operating panel and cabin push-button command systems.

In the elevator spare parts market, this board is commonly searched as:

• Mitsubishi Cabin Push Button Command Extension PCB
• Mitsubishi Car Expansion PCB
• Mitsubishi COP Command Board
• Mitsubishi Elevator Button Board
• Mitsubishi Push-Button Expansion Board
• Mitsubishi Elevator PCB Board

This board is usually related to COP button command expansion, cabin button input processing, or additional car operating panel signal connection.

Main Model References

This page can naturally cover the following model references:

• P235709B000G01
• LHS-270A
• Mitsubishi Elevator Button Board P235709B000G01
• Mitsubishi Elevator Car Expansion PCB P235709B000G01
• Mitsubishi Cabin Push Button Command Extension PCB LHS-270A
• Mitsubishi COP Command Board LHS-270A

Another market listing also uses the shorter name MITSUBISHI Elevator Button Board P235709B000G01, which means some buyers may search this product only as a button board rather than an expansion board.

Where This Board Is Usually Used

P235709B000G01 LHS-270A is usually associated with the car operating panel area.

It may be checked when the elevator has issues related to:

• cabin push button response
• COP command input
• button signal expansion
• car call registration
• button indicator response
• COP internal wiring
• command board communication with the main control system

If some car buttons do not respond, the cause may be the push button itself, the button wiring, the COP harness, power supply, or the expansion board. For this reason, technicians usually inspect the complete COP signal path before confirming the PCB fault.

What Buyers Should Confirm

For accurate supply, please check:

• P235709B000G01 marking on the board
• LHS-270A marking if visible
• front and back photos of the PCB
• connector quantity and direction
• COP installation position
• old button panel photo
• whether the fault affects one button, multiple buttons, or the complete COP
• related board numbers nearby if visible

This helps confirm whether the required item is a push-button expansion board, COP command board, or another Mitsubishi button-related PCB.

Practical Replacement Notes

Do not replace this board only by appearance.

Two Mitsubishi COP boards may look similar but have different button quantity support, connector layout, or signal configuration. Before installation, technicians should compare the old and new PCB carefully and check the button harness, connector oxidation, power supply, and car operating panel wiring.

If the original fault is caused by a damaged push button, loose connector, or COP wiring problem, replacing only the expansion board may not solve the issue.

FAQ

Is P235709B000G01 the same as LHS-270A?
Public supplier listings commonly show P235709B000G01 together with LHS-270A for Mitsubishi cabin push button command extension or car expansion PCB applications. The old board label should still be checked before replacement.

Is this board a button board or an expansion board?
Both names may appear in the market. It can be described as a push-button expansion board, COP command board, car expansion PCB, or elevator button board depending on the supplier and installation position.

What photos are useful before ordering?
Front and back PCB photos, close-up label photo, connector area, COP installation position, and old button panel photo are recommended.
