Plate support for electric control and signaling units, permitting insertion of a plate into and separation and removal of the plate from the plate support

摘要

A support for a display plate for electric control and signaling units has a frame portion receiving the plate and supporting the same on two inwardly extending protrusions thereof, and a table portion which has a recess for receiving a fastening ring nut of a control and signaling unit. Two support members are provided in the frame portion, which permit flexion and bending of the plate when the latter is pressed by a finger of the user so as to disengage and release the plate from the frame portion without the use of any tool.
