Abstract
A lamp includes a head, a support arm and a base. The head includes a light emitting member. The support arm is rotatably connecting to the head. The support arm includes a first pushing member and a second pushing member. The base includes a moveable contact and a stationary contact. The moveable includes a spring tab. When the support arm is rotated to a first position, the first pushing member abuts against the spring tab to be deformed, and the spring tab connects to the stationary contact. The light emitting member is in a power on state. When the support arm is rotated to a second position, the second pushing member abuts against the spring tab to be deformed, and the spring tab disengages from the stationary contact. The light emitting member is in a power off state.
