Specific Gravity Kit with Newton Scale and 3 Metal Cubes Light & Optics_Color A safety-door interlock prevents contact

A safety-door interlock prevents contact with energized electrodes by cutting power whenever the door opens

sized for branched circuits where additional plugs share a single terminal

this cover-protected single rheostat carries a constantan winding with 4mm safety socket terminals

Bobbin-wound coil for the demountable transformer with panel-mount 4mm sockets and an enclosed earth connection

and corona discharge
