Cigarette lighter

The challenge

This wheelchair user with limited grip in his hands and limited head movement enjoys smoking. His wife currently lights his cigarettes for him.

A car cigarette lighter was used, which is activated by pressing a very low effort lever that depresses a switch which operates a low current timer relay circuit that then operated a high current relay. The car lighter element was surrounded by a metal cylinder spaced from the base to allow cigarette ash to escape and then this cylinder was protected by a heat resistant plastic shield to prevent contact by the client. A universal clamp allowed the circuit box to be clamped as needed to any surface.

The client can now light his own cigarettes without troubling his wife
