Switches

Most battery powered, electrical and electronic household devices have small buttons, switches or dials that are inaccessible to some people with physical disabilities. Adaptive switches are designed to provide an alternate means of access to these devices. In their simplest application these switches are used to control just the on and off functions of devices such as lights, radios, tape recorders and battery toys. In more sophisticated applications, adaptive switches can be used to adjust volume or select channels on audio and video equipment, operate a telephone or access a computer. In all of these applications the switch must be used either with a device that has been adapted for switch access or in conjunction with an interface that links the switch to a non-adapted device.

Plate Switches

  • Activated with downward pressure
  • Amount of pressure to activate varies across products
