Pretorian USB Switch with Built-In Interface

The Pretorian USB Switch combines a low-profile 75mm assistive switch with a built-in USB switch interface. It connects directly to a compatible computer, phone or tablet, removing the need for a separate switch box for the main switch.

The function of the built-in switch can be selected using the controls and LED display on the reverse of the unit. A wide range of keyboard, mouse and gamepad functions is available, allowing the switch to work with different assistive technology software, educational activities and switch-access applications.

Two additional 3.5mm sockets allow external wired switches to be connected. The built-in switch and each external switch socket can be assigned a different function, creating a flexible one, two or three-switch access arrangement.

Adjustable switch-filtering settings can help accommodate different movement patterns. These include options for ignoring accidental short presses, preventing repeated activations, limiting the duration of a press and producing automatic repeated activations. When filtering is not required, the settings can remain off and the unit operates as a standard switch.

SEN and Access Benefits

  • Provides direct computer access without requiring a separate switch interface for the built-in switch
  • Offers a larger target area for users who find small keyboard keys, mouse buttons or touch controls difficult to operate
  • Low operating force can support users with limited strength or endurance
  • Programmable functions allow the switch response to be matched to the software or activity
  • Additional sockets allow external switches to be positioned around the user’s most reliable controlled movements
  • Acceptance Delay can help prevent brief or accidental contact from being registered
  • Ignore After Release can reduce repeated actions caused by difficulty moving away from the switch
  • Maximum Press Time can create a controlled output where the user cannot release the switch quickly
  • Auto-Repeat can provide repeated activations from a sustained press when appropriate
  • Can support greater independence with communication, learning, creative activities and computer access

Programmable Switch Functions

  • Keyboard functions: Includes commonly used commands such as Space, Enter, Tab, arrow keys and selected additional keys
  • Mouse-button functions: Includes left click, right click and drag lock
  • Mouse movement: Includes cursor movement in four directions
  • Gamepad functions: Includes four switch commands used by compatible switch-access software

The built-in switch and each of the two external switch sockets can be assigned independently. This allows different functions to be combined within the same access arrangement.

Adjustable Switch Filtering

  • Acceptance Delay: Requires the switch to remain pressed for a selected period before the activation is accepted
  • Ignore After Release: Prevents another activation from being accepted for a selected period after the switch is released
  • Maximum Press Time: Limits the duration of the switch output even if the switch remains pressed
  • Auto-Repeat: Produces repeated activations while the switch continues to be held

The filtering functions are adjustable and remain off by default. Pretorian recommends configuring them around the individual user rather than applying the same settings to everyone.
