ABSTRACT:
A lamp with an integral switch comprises a push switch knob assembly including a knob (33) mounted in a tubular member (31) and urged by a spring (33). The lamp can be mounted such that the switch knob (33) is maintained in its retracted position by something such as a closed trunk hood of an automobile thereby breaking the circuit between a power source and a bulb (4) of the lamp, and is allowed to be moved to its extended position under the action of the spring (33) making the circuit between the power source and the bulb (4). It can be conveniently used for automatically illuminating a trunk room of an automobile, for example, when its trunk hood is opened.
