Abstract
An automatic cigarette lighter comprises a thermal resistance element mounted in a sealed case and powered by a switch activated power supply. Operation of the thermal resistance element is controlled by a timer to heat for a predetermined time after activation of the switch and then to remain off for a predetermined period of time before reactivation is possible. The automatic cigarette lighter finds particular advantage in situations where naked flame is unsafe or undesirable. It is also useful in secure establishments, such as prisons.
