CA 2271265
Access is restricted to the push buttons on electrical switching apparatus by a device which includes panel members hingedly mounted in a frame secured to the switch over the push buttons. The panels can be locked in the closed position over the respective push buttons by inserting a locking device through moveable staples molded on the panel members which align with a fixed staple molded on the frame between the panel members. A catch on the underside of the fixed staple is engaged by catch ledges on the panel members to retain the panel members in the closed position without locking. The transparent panel members have apertures too small for a finger, but through which a push button can be actuated by a tool with the panel member closed.
