This modifier is typically used where the player has difficulty controlling how long they are pressing a switch. The modifier is plugged into the device that needs controlling and the players switch is plugged into the modifier. You can adjust the length of the output between 100mS and 200mS to suit the game or the required action. Battery powered and self contained. The LED on the front flashes once per activation. Ideally for football games but can be used on any device that needs a short switch closure. Variants can be made to special order. ONLY FOR USE ON COMPUTER GAMES AND TOYS. NOT FOR USE ON MOBILITY PRODUCTS.
