Dear friends,
I am invoved in designing special devices for operating handicapped kids power wheelchairs.
I use N.O. Mechanical Switches called Buddy Buttons mounted on Headrest or a Tray.
Touchung the buttons and hearing the click make a kid nervous and spastic. Please help me in finding compact Proximity Switches which can replace the mechanical switches on the Headrest or mounted under a Tray.
The voltage is 24V and the required operating range about 1/2-3/4 inch operated by the body: Head or Hand.
I thank you in advance.
Best regards. Izzy
