<p>In the present lighting device, the lead wires and the fastening members for components, including electric contacts in the electrical circuit, are made of spring steel wires. The resiliency of the lead wires, fastening members, and electric contacts is utilized to mount the switch actuating unit into the casing, whereby the overall construction may be simplified and even if strong shocks are applied to the apparatus continuously for a long period of time, the switching operation may be securely carried out.</p> |
