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).

This switch features a feather light touch – just 0.4 ounces or 10 grams of pressure is required to actuate! It also provides both auditory and tactile feedback. The activation surface is 1.75" x 0.5", with a 7 mm travel distance before actuation. It includes 4 stickers to allow individuals to use whatever high contrast color they desire (Red/Blue/Yellow/Green), or the default grey if preferred.

The Switch2Scan from Pretorian Technologies supports scanning switch access for "idevices", providing access to all iPad functions. Employing the Switch2Scan, users are able to use standard switches to control Apps, access media and iBooks, and even perform data entry.

The Switch2Scan can utilize either the Voiceover feature that is available in all releases of iOS or the Switch Control function which is included in iOS 7 and newer releases. The Swith2Scan connects to the idevice via Bluetooth wireless, leaving the viewing device free of inconvenient cords.

Switch Scanning will permit full access to functions with just a single switch but for enhanced capability the Switch2Scan will support the connection and programming of up to 4 standard external wired switches. The extremely small footprint and a long-life lithium-ion rechargeable battery make this a device of convenience. Scanning speed is variable, can be both forward and backward, and can be performed in manual or automatic modes.

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.
