Assistive Technology Loan Library item === This switch is used with the Powerlink 3 (separate checkout). The device can be used as a \ switch or you can attach any other switch to the device. The unique feature of this unit is that it provides CORDLESS switch access to electrical devices. If you would like to turn on a radio from across the room, this device (along with the Powerlink 3) could be used. This switch can also be cabled directly to a device (to be used without the control unit). Website: www.ablenetinc.com.
