Реферат: ABSTRACT OF THE DISCLOSURE A quick-mount device for a contactor which includes a housing in which is mounted a coil assembly having a coil and electrical terminals carried by a base plate. Opposite walls of the contactor housing include pairs of legs each carrying oppositely directing tangs or projections. A first of the oppositely directed projections engaging the lateral edges of the base plate and a second of the oppositely directed projections engaging lateral edges of a support rail. The two pairs of opposite directed tangs are so relatively positioned that a screwdriver can be inserted therebetween for manually freeing the tangs from engagement thereof with the support rail, yet maintaining the engagement of the other tangs with the base plate of the coil assembly, thereby permitting both quick-mounting and quick-demounting of the contactor relative to its associated coil assembly and/or support rail.
