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 really inexpensive switch interface ideal for use with switch operated software. Easy to use and no software to install – simply connect to a USB port on your computer, plug in one or two switches and you are ready to use programs.

The two jack sockets allow switch presses to send space and enter, allowing you to operate any software that can be controlled by these keys. It cannot be used with programs that require other switch inputs

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.
