Solid State Organ Systems

One input, 14 outputs, no contacts.

Key relays are still an efficient way to switch off-notes and extensions in consoles and chests. But older versions have their snags. Contacts corrode and burn, bearings clunk and tiny connections play havoc with organ-builders' eyes.

Next time you overhaul a conventional switching system, fit SSOS key relays. Fully compatible with all types of gang-switch, magnet and other hardware, each one silently controls up to 14 outputs with a total load of 4 amps. Each output, of course, can be used individually or connected together to switch returns or common-rails.

• Occupies exactly the same space and mounting centres as a Reisner C5 relay
• Outside dimensions 63mm x 38mm (2 ½" x 1 ½")
• 4-amp load over 14 outputs
• Can be coupled together to work from one input
• Fully spark-suppressed at input and all outputs

All polarities catered for.

SSOS's key relays are made in four different polarity combinations: positive or negative control, and positive or negative output:

621004AO: Positive control, negative output
621004A1: Negative control, positive output
621004A2: Positive control, negative output
621004A3: Negative control, positive output
