Fully bundled set to get you working away as soon as possible, with your chosen computer or device, switch-adapting to most AT software.


The Simple Switch Interface Set comprises of a pair of Pretorian Technologies Smoothie 75mm switches (1x Red & 1x Yellow), and a Simple Switch Interface.

Simple Switch Interface:

Simple Switch Interface is a simple, convenient and cost-effective way to connect up to two switches to your computer to access most assistive technology software.

To provide switch access to most AT software, Space and Enter is often all that you will need. However, if you are using the product as a method of providing mouse switches, it may be set to Left and Right click. Alternatively, access to Clicker from Crick may be provided by selecting F7/F8 and similarly, access to The Grid from Smartbox can be gained by using Gamepad 1 and 2.

Whatever the appropriate switch functions, Simple Switch Interface retains the settings even when powered down so it will always be set the way you want it.

As with all Pretorian products, no drivers are required, making it ideal for installation on computers which are under maintenance contracts.

Smoothie 75mm Switches:

The Smoothie 75 is a 75mm (3”) diameter wired AT switch, terminating in an industry-standard 3.5mm jack.

The switch has an extremely low profile and is angled towards the user, meaning that the operating surface is only 10mm above the desk at its lowest. Smoothie 75 switches do not have a flanged base, allowing unrestricted access to the operating surface.

Users who are unable to rest their hand on the switch without operating it may instead rest their hand on the desk in front of the unit and simply ‘roll’ it towards the switch when required.
