Mitsubishi Push-Button Expansion Board P235705C000G01

Mitsubishi Push-Button Expansion Board P235705C000G01 is used in Mitsubishi elevator car operating panel and cabin button command applications.

This board is commonly associated with the model reference LHS-210A. In the elevator spare parts market, it may also be searched as:

• Mitsubishi Elevator Button Expansion Board
• Mitsubishi Elevator Button Communication Board
• Mitsubishi COP Button Board
• Mitsubishi Cabin Push Button Board
• Mitsubishi Car Operating Panel Button Board
• Mitsubishi Elevator PCB Board

The main model references for this page are:

• P235705C000G01
• LHS-210A

This board is usually installed inside the car operating panel area, where it supports button command input, COP signal expansion, or communication between elevator push buttons and the elevator control system.

COP Button Expansion Application

P235705C000G01 should be understood as a button expansion or button communication PCB, not a single elevator push button.

It may be checked when the elevator has issues such as:

• car button not responding
• partial COP buttons failing
• car call not registering
• button indicator signal abnormality
• intermittent cabin button response
• COP signal communication problem
• visible PCB or connector damage

These symptoms may also be caused by the push button itself, COP wiring harness, connector terminals, power supply, or related communication circuit. For this reason, technicians usually check the complete COP signal path before confirming the PCB fault.

Model Confirmation Notes

Before ordering Mitsubishi Push-Button Expansion Board P235705C000G01, please check:

• Complete P235705C000G01 marking
• LHS-210A marking if visible
• Front and back photos of the PCB
• Connector quantity and direction
• COP installation position
• Old car operating panel photo
• Existing button or communication fault description
• Nearby board numbers if visible

If the old board label is unclear, a full photo of the car operating panel interior and close-up photos of the PCB marking can help confirm the correct replacement faster.

Practical Replacement Notes

Do not select this board only by appearance.

Mitsubishi COP button boards may look similar, but the supported button quantity, connector layout, communication function, and board version may be different. Before installation, technicians should compare the old and new PCB carefully and check the button harness, connector oxidation, power supply condition, and related COP communication circuit.

For overseas buyers, sending clear photos of the original P235705C000G01 / LHS-210A board before shipment is the safest way to reduce wrong supply.
