Assistive Technology Switch Access Devices

Learning and teaching switch skills to children with special needs will now be a little easier because of the Switch Filter. Especially for those children who need to overcome a tendency towards multiple switch “bashes” or “banging” either deliberately or through lack of motor control.

The Switch Filter works by letting the first switch press operate a connected device e.g. an adapted toy but then introduces a delay before the next switch press does anything.

For example, the childs' first switch press passes through the filter and turns on the toy. But a second press or multiple switch "banging" would do nothing until the delay period, set by the filter, had passed.

The delay period is easily changed from long (~10secs) to short (~2secs) by plugging the input switch into one of the three sockets on the front panel. The connected device e.g. toy is connected to the socket on the side panel using the lead included with the Switch Filter.

The kit is supplied with the Switch Filter, a 3.5mm jack plug to plug connecting cable and 9 volt battery.

This Anti-Tremor Switch will help individuals overcome switching problems caused by an involuntary tremor or pressing a switch more times than is intended.

It works by preventing repeat switch presses from getting through to cause unintended switching. Three time filters (2, 6 or 10 seconds) are programmed into the device to cover the needs of most individuals.

Set-up is very simple. All that's necessary is to connect the Anti-Tremor device between the user's normal switch (e.g. button, squeeze, blow, lever type etc.) and the equipment being switched, for example one of our switch adapted Dream-Toys or bubble machines.

Three simple steps:

1. Plug the user's normal switch into one of the sockets on the front of the Anti-Tremor device.
2. Use the cable (supplied) to connect from the Anti-Tremor Switch "output" to the "input" on the device being switched e.g. computer interface. (Plugging in the cable also turns the device on. When finished, disconnect the cable to conserve battery life.)
3. Start playing or working.

The kit is supplied with the Anti-Tremor Switch Filter, a 3.5mm jack plug to plug connecting cable and 9 volt battery.
