Cover system with protection against accidental contact for a switchgear cabinet and a suitable fastening system.
A switching cubicle has a housing and supports inside for various apparatus, the supports all being long rails (11,12) at right angles to each other and connected at certain places (13). The front sides of the rails all lie in the same plane. On these sides are series of holes used to fasten two cover plates (40) with snap-action screws. These screws have flexible collars on the shafts which engage with corresponding support surfaces of the cover plates. These give high mechanical stability and increased versatility to the support rails plus secure seating without play for the cover plates. <IMAGE>
