The Smoothie Switches from Pretorian are low profile, low force, large diameter switches for the ultimate in easy and comfortable switching.

Features:

• Operates over the whole switch area of 75mm or 125mm).
• Extremely low profile and operating force. (see specifications)
• Tactile feedback.
• Available in four colours (red, yellow, blue, green).
• Industry standard fixing holes for easy mounting (125 mm models only).

The X-Keys USB 12 Switch Interface from PI Engineering is the ideal solution where a high number of commands, complex macros or long strings of data need to be entered by a single action. Equipped with 6 input ports this interface can accommodate up to 12 switches with the use of optional splitter cables. With the ability to accept input from switches located up to 1000 feet from the interface module this can be used to activate commands from multiple remote locations, such as in interactive kiosks at museums. The interface memory can retain approximately 1000 keystrokes or commands and is easily reprogrammed using free software for PC, MAC or Android systems.

This is a very thin membrane switch (travel distance 0.05 cm) which provides no tactile or auditory feedback. It is activated with a light touch (1.8 oz / 50 grams) on the colored circle (2" diameter). The exposed surface is sealed to prevent moisture damage. Comes with 5 bright colored stickers: Red, Green, Yellow, Blue and Orange (as shown in picture).

One of the 'core switches' in the industry, this switch features a 2.5" (6.4 cm) activation surface and is recommended for individuals who can (or prefer) to access a smaller target area than other circular switches such as the Buddy Button. It provides both tactile and auditory feedback, requires average force (2.5 oz / 71 grams) and has a 0.0635 cm travel distance before actuation. It includes 4 interchangeable switch tops which can be removed and replaced with the color of choice: Red, Blue, Yellow, and Green.

The Single Pedal Accessory for Savant Elite2 is an add-on pedal that must be connected to a programmable (jack-equipped) Savant Elite2 Foot Pedal or to any other programmable control module that can accept a 3.5mm phono plug connector (i.e. the accessory pedal is not programmable, has no control module of its own, and cannot be connected to a computer without an appropriate programmable interface.) When connected, the Single Pedal Accessory can be used to generate any command assigned to the associated jack, such as mouse clicks, combination keyboard shortcuts and multi-key macros. When added to an expandable interface that has available connections an additional pedal provides access to a greater number of commands and functions, and assists in further reducing the load on the hands and fingers. This wired pedal can be positioned up to ten feet away from the control module.

The Single Pedal Accessory for Savant Elite2 has a low-profile housing and is hinged at the front. This permits the operator to rest their foot on the pedal with minimum risk of accidental activation. The pedal also features independent tension adjustment to allow each person to personalize the degree of activation resistance, and threaded inserts and adhesive velcro tabs to secure it in place should that be desired.

Note: The Single Pedal Accessory provides no functionality on its own. Command functionality can only be accomplished by connecting this to a programmable Switch Controller, pre-programmed device, or Switch-activated device.

This switch features a 5.0" (12.7 cm) activation surface and is recommended for individuals who can (or prefer) to access to the largest possible target area due to visual or motor impairment concerns. It provides both tactile and auditory feedback, and due to its size requires higher than average force (5.5 oz / 156 grams) and has a 1.143 mm travel distance before actuation. It includes 4 interchangeable switch tops which can be removed and replaced with the color of your choice: Red, Blue, Yellow, and Green.

The Test-It Switch Tester from Pretorian provides a quick and easy way to test your switches before beginning work with them. This is particularly timesaving when working with multiple switches, switch interfaces, computer equipment and users.

This highly durable switch is designed to meet the challenging requirements of wheelchair users and is waterproof and dust proof. The design allows for mounting on any flat surface and all mounting solutions are included in the price. The activation surface is 0.5" square and features a very high force (11 oz / 300 grams) which prevents accidental actuations. It provides both tactile and auditory feedback, and has a 4 mm travel distance before actuation. It includes 4 stickers to allow use of whatever high contrast color is desired (Red/Blue/Yellow/Green), or the default grey if preferred.

X-Keys Orby Switches from PI Engineering offer users a low (100 g) activation force with a clearly audible click for notification of both activation and deactivation. The 2.5" diameter surface activates the switch from any contact location and is large enough to provide a significant target zone without being two large for practical placement. The brightly coloured (Red, Yellow, Blue, and Green) buttons are highly visible and lend themselves to serve as visual cues to aid in identifying the command to be performed.Orby Switches connect to any control module or switch-adapted device that accepts the industry standard 3.5 mm plug. For stability Orby switches feature a non-slip backing or can be secured using the dual threaded brass inserts.
