摘要： A hand-operated portable electric ignition device for the ignition of gas comprises within an insulating housing means for producing from a battery relatively high voltage alternating current pulses in response to the operation of a manually-operable switch, said means including a transistor oscillator circuit, rectifying means for rectifying the alternating current pulses for charging a capacitor and means arranged to conduct to provide for the discharge of the capacitor through the primary of a transformer in the output circuit of which is a spark gap across which sparking occurs when the charge voltage on the capacitor reaches a predetermined value. The manually-operable switch comprises an actuating button which is slidably mounted in the housing and which engages with a free end of springy relatively stiff wire constituting the moving contact of the switch and in response to the depression of the actuating button the wire contact makes wiping contact with a fixed contact plate having its contact edge disposed oblique to the direction of movement of the actuating button.
