When no other switch will do...! The Twitch Switch is activated by small muscle movements, such as wrinkling the forehead. It can be easily adjusted to increase or decrease the amount of muscle movement needed to activate it. The Twitch Switch operates in three modes: latched, momentary and timed. Use the latched mode when operating a device that needs to remain on until the user wants to turn it off; the momentary mode when operating a toy or communication device; and the timed mode when operating a device that you want to stay on for a pre-set period of time (adjustable from 1 to 120 seconds). Set of 3 extra sensors now available separately.

Requires 1 9-V Battery. Please Note: This product is not returnable due to sanitary reasons noted by OSHA standards.
