These versatile miniature switches have 25.4 mm diameter moulded wafers and are available in
2 versions, 36° indexing - having 18 clip positions and 30° indexing - having 22 such positions. 15°, 45°
and 60° indexing are variations of the latter.Optional features include concentric shafts, panel and
spindle seals, printed circuit termination’s and momentary contact models.
(see Bulletin RW36 for full technical details).
The low friction moulded cam followers in the assembly ensures a smooth indexing action.
Balance pressure springs provide consistent and readily reproducible total switch torque values
within the following ranges.
Type A indexing mechanism may also be used as an alternative where a simpler, space saving
mechanism is required. The switch then becomes model A-MA. 30° indexing only.
