We are now offering the lower cost cousin of the 04 series from Elma. The smaller blue bodied 01 series, 01-2263 offers you the option of not only wiring your 2 channel signal inputs but also dedicated earth points for each position. This 4 pole 6 way switch is shorting, make before break. (Elma do not offer the non-shorting version). So ideally used as a selector switch for 2 channel with earth or to control your XLR inputs.
