Furthermore, with the operation of the spring element (52), the position of the press detent (542) can directly move the position of the sliding piece (51) to form a sliding mechanism, and subsequently making contact for the conductor (53) to the first electrical contact (42) and the second electrical contact (44), completing the electrical connection to the electrical circuit (40), or the disengaging the conductor (53) from the first electrical contact (42) and the second electrical contact (44) to be an open circuit.

[0015] Additionally, the case (10) can provide with two parallel protruding strips (14, 15), where the sliding piece (51) is sandwiched in between, and the two protruding strips (14, 15) are in parallel with the extension rod (540). The two protruding strips (14, 15) are mainly for restricting the sliding piece (51) to move between the first position and the second position in parallel to their direction.

[0016] The spring element (51), such as a spring, is a mechanical element with elastic recovery force, and the spring element (51) is connected at one end to a stopper (16) in the case (10), and the other end is secured to the notch (55) on the sliding piece (51).

[0017] Based on the aforesaid inventive lamp structure (1), the conductor (53) on the sliding piece (51) can selected either state of the close circuit state or open circuit state between the first electrical contact (42) and the second electrical contact (44), in which, the close circuit state is the state of the conductor (53) electrically connected to the first electrical contact (42) and the second electrical contact (44), the open circuit state is the state of the conductor (53) disengages from the first electrical contact (42) and the second electrical contact (44); the first position corresponds to the open circuit selected by the sliding piece (51) and the second position corresponds to the close circuit selected by the sliding piece (51); and the protruded position of the press detent (542) relative to the surface of the case (10) corresponds to one of the first position and second position of sliding piece (51).
