A system includes (i) a module configured to be mounted on a panel and (ii) a clamp. The clamp includes a retaining section configured to receive and retain a threaded structure. The retaining section is also configured to be connected to and apply force against the module. The clamp also includes a contact section configured to contact the panel and apply force against the panel. The clamp further includes a connecting portion connecting the retaining section and the contact section. The connecting portion is configured to allow part of the threaded structure to contact the contact section in order to create the forces applied against the panel and the module. The connecting portion can be elastic such that a separation of the retaining section and the contact section changes as the threaded structure pushes against the contact section.

An apparatus for attaching a panel mounted electrical component includes an L-shaped bracket. The bracket includes a horizontal member having a frontward facing edge and a rearward facing edge. The bracket further includes an opening on the horizontal member that is configured for receiving a panel mounted electrical component. A vertical member is aligned along the rearward facing edge of the horizontal member. The vertical member is integral with the horizontal member and defines a ninety-degree angle. A plurality of openings located on the vertical member are configured for receiving fasteners to attach an outward facing surface of the vertical member to a surface. The bracket also includes a lip that is vertically aligned along the frontward facing edge of the horizontal member. The lip is integral with the horizontal member and defines a ninety-degree angle.

A switch seat body assembling structure includes a main body for assembling with a switch component. The main body is composed of a metal head section in the form of a thin sheet structure and a nonmetal belly section. The main body is defined with an eccentric axis and has a shaft hole positioned on the eccentric axis. The metal head section has a first wall normal to or inclined from the eccentric axis and a second wall connected with the first wall and parallel to or inclined from the eccentric axis. The first and second walls together define a space. The nonmetal belly section fills the space to connect with entire sections of the first and second walls as an integrated body. The switch seat body assembling structure improves the problems that the processing and manufacturing processes are time-consuming and troublesome and the material cost is higher.
