Abstract
A spacer which serves to space and connect two panels which are arranged parallel, one behind the other, in particular for uniform distance setting between the front panel of a switchboard and a backside, parallel printed circuit board. The spacer includes a socket and a plug member which is engageable with the socket. The socket exhibits, concentrically around its central axis, at least four guides that are open in the direction of the plug member and which have a depth defined by stop faces of the socket. These guides form groups of varying depth, which lie radially symmetrically to the central axis, and the plug member has on a side thereof facing the socket, projections which are rotatable into suitable positions into the guides of a group.
