Glasshouse / Elma 2-pole 24-way switch / Stereo Stepped Attenuator
The Elma 04-2133 is a make-before-break type, 2-pole 24-way switch. So, it features one more step than its 23-step counterparts. It is Swiss-made and has a quality feel. It is a non-magnetic-bodied switch with 3-micron gold-plated contacts over copper alloy. All contacts are enclosed to avoid noisy contacts caused by dust.
This version offers 24 volume positions from mute to near total volume through our tried-and-tested 2dB step values of resistors. The switch's front does possess a "non-turn" lug of 3mm squared that protrudes from the front panel, close to the bush. See the datasheet below. If not required, this can be removed with a file.
We offer the option to choose from 16 different resistor types for this kit.
Dimensions
Shaft: 6mm diameter x 15mm length
Bush: 10mm diameter x 11mm length
Body, including resistors fitted (internal part): 33mm x 40mm (oval shaped) x 45mm height
