Glasshouse / Elma 4-pole 24-way switch / Stereo Ladder Stepped Attenuator

Swiss-made Elma switches have been a strong favourite of the DIY community for some time, though as their prices seem to be constantly on the rise, Japanese Sieden switches seem to be more in favour. They offer highly durable switches with a non-magnetic body and 3-micron gold-plated contacts over copper alloy. They have 24 positions at 2dB steps, giving a usable sweep.

We offer the option to choose from 15 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 76mm height  

PRICE (1 off) 10K, 20K, 25K, 50K, 100K, 250K
starting at £204.07+vat+p&p

Due to the range of values for the Audio Note resistors, we can only supply the 50K, 100K, and 250K options. For the Takman resistors, we can only supply the 25K and 50K versions of the Carbon Film and the 20K, 25K, and 50K versions of the Metal Film.

Available as a kit or fully built. The build price is an additional £80.
