More Details

Switches
* To activate the switch, it is usually depressed by a part of the body (e.g. hand, foot, head, knee) in order to close the microswitch and complete the circuit.
* Switch housings can alter the amount of force required to close the microswitch.
* Pressures necessary to activate a switch range from a light touch to a significant force.
* A non-mechanical switch does not require force for activation. The most common example of a non-mechanical switch involves breaking an infrared beam, similar to a burglar alarm.

Interfaces
* It is not possible to plug switches directly into commercially available equipment such as toys, computers or electrical devices. The equipment must be modified or some type of interface must be used. Interfaces provide a link between the device/equipment and the means by which to operate it.
* There are numerous types of interfaces, some of which provide a simple connection whilst others allow sophisticated customisation.

There is an immense variety of switches available to suit the varied needs of individuals. There are also several interface options available. Suppliers and specialist resource centres may be contacted for further details.

Standards

Standards
Some assistive technology needs to meet Australian or other standards. Standards may relate to materials, manufacturing and installation. Products that meet Australian or international standards will have written certification. To find out if a product meets Australian Standards ask the supplier to show you the certificate. For more information about standards also see

TGA
Many of the items on the Assistive Technology Australia website are categorised as a Medical Device. Medical devices that are approved for use in Australia have been entered into a national database called the Australian Register of Therapeutic Goods (ARTG), which is maintained by the Therapeutic Goods Administration (TGA). You can ask the supplier for the ARTG number for the device you wish to purchase and search the ARTG for the entry. To access information on the ARTG visit www.tga.gov.au

When buying a medical device it is advisable to only choose a medical device that is recommended by a healthcare professional and has been included on the ARTG.
