Switches and switch accessories

Switches come in all shapes and sizes. One click of a switch can send a variety of simple messages to a computer. How the computer acts on this signal depends on the program that is running. The possibilities are endless! A switch can activate simple cause and effect programs that build pictures and/or play animations. Other, more advanced programs can use a signal from a switch to write letters and emails, surf the Internet and control practically all computer tasks.

When choosing the right switch for you, you need to answer these questions:

• which muscles (arm, wrist, finger, leg, head...) could you use best to control a switch?
• what kind of switch can be activated by these muscles?
• how much force can you generate to activate the switch?
• where and how is the switch to be mounted?

Once you have the answers, a more informed decision can be made on exactly which switch is best suited to your needs.

Most common movements can activate a limb, and therefore a mechanically activated switch would be sufficient. If the muscle doesn’t move a part of the body, a muscle movement sensor may be the answer. If the person can make a sound, then a sound activated switch may do.

Most switches have brackets or holes that allow them to be mounted onto a mounting device. These mounting devices allow the switch to be placed within comfortable reach of the switch user.

Many of the switches below have audible and tactile feedback. This means that when activated (switched) they make a sound and/or have a physical feel to them. If there is no feedback, you may not know if you have activated the switch correctly. Some switches produce a sound electronically when pressed.
