DESCRIPTION
Elma's Uni Selector is a versatile, multi-deck selector switch specifically designed for bounce sensitive, analog switching applications. The switch offers various torque options ranging from 1.5 to 15 Ncm while providing up to 12 position (30° indexing) or 24 position (15° indexing). The functionality per wafer comprises up to 4 poles x 3 or 6 positions (shorting or non-shorting) and up to 6 wafers. The number of positions can be customized by the user installing an end stop screw to the positions of his preference (to be ordered separately).
The Uni Selector comes with rectangular pin headers which allow the switch to be mounted horizontally on a PC board. For remote control applications, Elma offers motorized IR-remote kits (Remote Audio Plus), that can be directly attached to the switch.
