1. Technical Field
The present disclosure relates to table lamps and, particularly, to a foldable table lamp having a power switched off when the table lamp is folded.
2. Description of Related Art
A foldable table lamp can be folded when not in use. Although conventional foldable table lamps satisfy basic requirements, a foldable table lamp, which includes a power switch that can be switched off when the table lamp is folded, is still needed.
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of a foldable table lamp. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
Embodiments of the present disclosure will now be described in detail below, with reference to the accompanying drawings. Referring to
The head 11 includes a light emitting member 111. The support arm 12 includes a first bar 121 and a second bar 122 substantially parallel to the first bar 121. In the embodiment, the distance between the first bar 121 and the second bar 122 is the same as the width of the head 11. The head 11 can thus rotate to be fully received between the bar 121 and 122.

To receive the connecting end 123, the base 13 defines a receiving space 131.
The space 131 includes sidewall 132. The sidewall 132 and the connecting end 123 form a gap 133 (see
The circuit board 14 includes a first stationary contact 141, a second stationary contact 142, a first slot 143, a second slot 144, a first opening 145, and a second opening 146. The contact 141 is adjacent to an edge of the circuit board 14. The first slot 143 and the second slot 144 extend along a lengthwise direction of the circuit board 14. The first opening 145 and the second opening 146 extend along a widthwise direction of the circuit board 14. When the stationary contact 141 and the stationary contact 142 are electrically close, the light emitting member 111 is in a power on state. When the stationary contact 141 and the stationary contact 142 are electrically open, the light emitting member 111 is in a power off state.
The movable contact 15 includes a main body 151, a spring tab 152, a arm 153. The spring tab 152 extends from one edge of the main body 151, and the arm 153 extends from an opposite edge of the main body 151. The movable contact 15 further includes a first sidewall 154, a second sidewall 155, a first mounting tab 156 adjacent to the spring tab 152, and a second mounting tab 157 adjacent to the arm 153. The end of the spring tab 152 protrudes from the sidewall 132 of the receiving space 131, and is movably received in the gap 133. The arm 153 is in contact with the static contact 142. The first sidewall 154 is securely received in the first slot 143, and the second sidewall 155 is securely received in the second slot 144. The first mounting tab 156 is securely received in the first opening 145, and the second mounting tab 157 is securely received in the second opening 146.
