TL;DR: A push button switch comprises a switch body defining an enclosure; a support member disposed within the enclosure, a pivotable converter supported by the support member for pivoting between the first and second positions with respect to an imaginary fulcrum plane; an operator actuable push rod extending through the switch body into the enclosure and having a converter actuator for pushing against the converter so as to pivot the converter in the direction of the second position thereof when the push rod is displaced from an unactuated limit position as mentioned in this paper.

TL;DR: A switch with an indicating mechanism which is visible or concealed depending on whether the switch is ON or OFF is discussed in this paper, where the indicating mechanism is mounted within a switch activator (e.g., a handle or actuator button).

TL;DR: The switch flourish plate as discussed by the authors includes slots opposite to each other in two faces of the walls of an aperture in said flourish plate and clamping projection provided adjacent to either of said two slots.
