Mounting Adaptive switches

Some of the children at school access computers by using adaptive switches with their head and chin. I am looking for solution that allows us to mount the switches in different positions to suit different childrens needs.

 Double head switch mount for a chair

This cheek, compact switch can be moved to accommodate different size heads.

two individual switch mounts

This is a single mechanical 'click' switch mounted round the neck on a tube for simple operation by chin movement.

The flexible tube can be cut to length to hold the switch under the user's chin.
