The MFZ Ovitor ON/OFF key switch (flush mount) is a control accessory used with Marantec industrial door control units (notably CS300 / CS310 / CS320 series).

• It is designed for secure activation or isolation of control voltage via a key-operated switch.
• Typically installed flush-mounted in the control housing lid or panel.
• Used in industrial door systems (sectional doors, roller doors, shutters) where restricted access is required.

It functions as a maintained ON/OFF selector (key retained or removable depending on version) controlling command enable/disable rather than direct motor power switching.

• Identified in accessory listings as:
  “MFZ Marantec Ovitor Assembly Kit CS310/320 Key Switch”

Functional Role

From control system documentation:

• Key switches are integrated as command devices within the control circuit
• Used in systems that may include:
  • OPEN / STOP / CLOSE push buttons
  • Emergency stop
  • Main switch or selector switch
  • Key switch (ON/OFF enable)

In practice:

• ON position: enables control circuit / operation
• OFF position: disables operation (lockout)

Mechanical / Mounting

• Mounting type: Flush mount (panel or housing lid)
• Installation location:
  • CS310 / CS320 control housing lid or panel cut-out
• Supplied format:
  • Often supplied as an assembly kit (switch mechanism only; enclosure lid may be separate)

Electrical Characteristics

(Derived from control system interface and accessory function)

• Function type: Maintained contact (ON/OFF)
• Circuit role: Control voltage switching (NOT main power switching)
• Integration: Connected to control board inputs (e.g., CS310 input terminals)
• Typical control voltage circuits:
  • Low-voltage control circuits (commonly 24 V DC / similar industrial control voltages – varies by controller)

Compatibility

Used with MFZ Ovitor / Marantec industrial control systems, including:

• CS 300
• CS 310
• CS 320
• FS / AS / MDF control families (where key switch option exists)

Application Areas

• Industrial sectional doors
• Roller shutter / roll-up doors
• Commercial gate and door automation
• Situations requiring:
  • Access control
  • Operator authorization
  • Lockout of door movement

Key Features

• Key-operated security control
• Prevents unauthorized operation
• Simple ON/OFF enable logic
• Designed for integration into control enclosures
• Industrial-grade accessory (aligned with heavy-duty door systems)

Important Notes / Limitations

• This is not a standalone product with a full standalone datasheet — it is:
  • A modular accessory / spare part
  • Defined mainly within control system documentation
• Exact specs (like IP rating, key type, current rating) are often:
  • Not listed separately
  • Dependent on the specific assembly kit variant or enclosure

Specifications: Robust metal housing; Timeless design; Protection: IP54
