Electronic Components General Advanced industrial process automation and measurement systems often require the input of data from an Operator. With simple systems of small complexity this is normally the input of a number or code. Multiswitch, the family of thumbwheel switches from Crameda Intersys, are the ideal device for this purpose. The design principle is that of a step switch but deviates from conventional switches in that the switch shaft is not perpendicular but parallel to the front panel.

Electronic Components Terminals Multiswitches are equipped with pin connections as standard. Alternatives are: solder pins or wire wrap pins. Dummy switches Dummy switches appearance is identical to the standard switches. However, the dummy switch has no contacts or printed circuits inside. It can be useful in satisfying aesthetic layout requirements. Dummy switches are not available for series D or Z. Limit stops Upon request, all Multiswitches, except series D and Z, can be provided with limit stops.

Electronic Components Division module A switch assembly may contain several switch groups separated by ribbed division modules. The dimensions of a division module correspond to those of a switch module. Division modules are available in series A, L, M, Q, U, V and W. End brackets and block assembly The individual switch module can be arranged into block assemblies. These are complemented by two end brackets and held together with threaded rods.
