Centronics 36 4-Way Manual Data Switch Box - Metal Shielded Switch

In this review of the Centronics 36 4-Way Manual Data Switch Box, the bottom line is simple: this small, sturdy switch is for technicians and labs that need a reliable, manual way to route parallel Centronics 36 connections between multiple devices. The biggest reason to buy is its all-metal, fully shielded case and heavy duty sealed rotary switch, which together make it a durable, low-noise solution for switching between four Centronics ports without rewiring. It is a no-frills, mechanical selector built for continuity and protection against EMI/RFI interference.

Key Features

• Four-to-one routing: Lets a single Centronics 36 endpoint be switched to any of four Centronics 36 ports, simplifying device sharing and testing.
• Fully shielded metal case: The metal enclosure reduces EMI/RFI interference for cleaner signal integrity in electrically noisy environments.
• Heavy duty sealed rotary switch: The sealed switch is designed to resist dust and moisture, improving long-term reliability in workshop use.
• Rubber feet: Small rubber feet protect bench surfaces and keep the switch stable during operation.
• Smooth manual dial: The smooth-turn dial offers positive tactile feedback for quick, unambiguous switching between consoles or devices.

Who It's For

The switch is aimed at equipment technicians, labs, and small offices that still use legacy Centronics 36 parallel ports and need a robust, manual way to select among multiple devices without replugging cables. It suits environments where EMI shielding and a sealed rotary control are important, such as manufacturing test benches or older print server setups.

Those who need remote switching, auto-sensing, or networked control should look elsewhere because this model is a straightforward manual selector with no electronic switching, software, or power requirements.

Pros & Cons

Pros

• Durable fully shielded metal construction reduces interference and protects internal wiring.
• Sealed, heavy duty rotary switch provides long service life in dusty or workshop environments.
• Clear four-to-one Centronics 36 routing removes the need to repeatedly plug and unplug cables.

Cons

• Manual operation only, so it offers no remote control or automated switching features.
• Designed for Centronics 36 interfaces only, so it is not compatible with modern USB or Ethernet peripherals.
