A pendant mounting structure comprises a main body, a cantilever and two latching elements. The main body includes a first surface and a second surface opposite to the first surface. The cantilever protrudes from the first surface. The latching elements protrude from the second surface. The pendant mounting is separately manufactured and latched to a housing. Thus, when an external force exerted on the cantilever is more than the offset limit of the cantilever, the cantilever could be cracked to protect the housing from being damaged.
