Removed from PHILIPS FM828 Transceivers (Channel Select) however these very high quality mechanical rotary switches are not limited to use in that equipment only.

Who is ELMA? Established in Switzerland (1960) designing and manufacturing a wide range of high performance switches but now they are a large worldwide company that is known for their embedded computing solutions including integrated chassis systems, board products, modular enclosures, equipment cabinets and precision hardware components in standard and custom configurations.

ELMA - Rotary Switch

Made in Switzerland

Part: Unknown (no ID markings on the switch other than the company and country of manufacture)

Configuration: 1 pole, 10 positions

Completely sealed body (I am unable to determine the wiper metal used but suspect gold or silver plated)

Actually the switch has 12 solder tag positions but seems to be physically locked at utilising only 10 of the positions

Small diameter (4mm) round shaft WITHOUT a flat spot - you will need to use a 'collet style' knob with these switches

Supplied with assorted aluminium hardware as originally used with the Philips equipment, this hardware may assist in mounting of the switches onto a panel.

Gold plated solder tag terminations

DIMENSIONS:

Switch main body: 18mm diameter

Shaft diameter: 4mm

Shaft length: 26.5mm

COSMETIC CONDITION:

Clean

No damage to the switch at all

Solder tags have been desoldered and are relatively clean ready for reuse.

TESTING:

Tested while still installed in the Philips equipment, working fine with no signs of intermittent or erratic wiper contact

Now sealed in plastic to maintain the present condition, ready to be used once again!
