Switch Me On!

Today in class we saw but a small number of the types of switches that can be used to allow the user some independence and control of their environment. Who would have guessed there were so many different needs and so, so many different functioning switches. Having never worked with a student requiring a switch device, I had very little understanding and/or knowledge about switches so today's class was very helpful in providing me with some knowledge about this mid-tech tool. Here is just a sampling of the switches that are available.

Switches are used to operate anything electronic for many different purposes. They are designed to allow the user access to appliances. This is known as environmental control. They also allow for play and exploration, movement, computer access and communication. Depending on the needs of the individual the use of the switch will vary. Switches tend to be activated by: pressure, motion, air flow (pneumatic), light sensitivity (blinking) or sound (clucking of a tongue). Most switches will respond to minimal movement. I found a great website that shows a seemingly endless number of types of switches and it provides a description of what each are used for. Visit Enabling Devices to view these switches by clicking on Capablity Switches. You can also view video's about the devices.

Switches are selected for each individual based on their most reliable switch site. The switch site is the part of the body that the individual is most reliably able to control with minimal use of energy. The switch should not be located at a site that has a reflexive pattern of movement. An Occupational Therapist will help determine the best site for the switch.

The following video shows Ben using three different switch sites to access his environment.

I hope you take the time to visit these websites. There is some really good information about switches and it helps show that the possibilities are endless! That means everyone has access to the environment around them.
