Further in use, the abutting surface 2511 of the abutting portion 251 can extend into or insert into the concave cavity 154 via the opening of the concave cavity 154. In embodiments according to Figure 2 to Figure 4 As shown, the concave cavity 154 has a depth dimension d21; the depth dimension d21 is less than the second width dimension or maximum outer diameter d12.

Further, the abutting portion 251 only partially extends into the concave cavity 154, rather than completely extending into the concave cavity 154.

In particular, the abutment portion 251 of the second electrical contact 250 is movable relative to other portions. In turn, the second electrical contact 250 / abutment portion 251 is transitionable between an elongated state and a compressed state. Also, the second electrical contact 250 / abutment portion 251 is biased to return to the elongated state. When the cover element 210 is turned to the closed position, the second electrical contact 250 / abutment portion 251 is in the compressed state.

[0105] Alternatively, in embodiments, when the atomizer 100 is received and incorporated within the power supply body 200, the second electrical contact 250 / abutment portion 251 is compressed or squeezed by the atomizer 100, in turn, pressed by the atomizer 100 to the compressed state.
