ABSTRACT:
Inner and outer electrical switches are attached in ganged face-to-face relation to a mounting plate by a screw which extends through two upper alined holes of the switches, by a pin which projects from the plate and into a lower hole of the inner switch, and by an L-shaped locking element having one leg extending through a lower hole of the outer switch and into the lower hole of the inner switch. The other leg of the L-shaped locking element is torsionally loaded and is adapted to be clamped between the head of the screw and the outer side of the outer switch.
