HISTORY:
Sustainability is the name of the game! Anything (that has been tested and still functioning properly) should be repurposed creating saving in wasted Ee and reducing the poisoning our environment when items are buried in the earth at the local tip needlessly.
Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.

This component is from the MATSUNAGA (Yokohama Japan) Frequency Converter, intended for laboratory use and providing up to 240V AC at a user adjustable variable frequency. Not only that, the AC voltage output could be varied across a wide range AND the user could set current limiting, so it could alter all three aspects of the AC output wavefrom, frequency, voltage and current limiting. I actually fired this gear up and it was working great but oh dear! What to do with it? Sure you could put up on the workbench but at that sort of weight it needed a lot of space and a good solid workbench. I decided a while back to offer this equipment as a complete unit "elsewhere" online for a while but there was no interest at all so I pondered over what to do with this equipment (to keep or not to keep) but it had a few things going against it.
As a complete unit it was EXTREMELY HEAVY, over 50Kg, which means that my arms are now 30cm longer from lugging this beast around the workshops! ... but more seriously, shipping would have been difficult to ensure safe travel AND very expensive. It also had other minor cosmetic issues because it is not easy moving such a monster around so it suffered scrap marks on various places of the all steel casing.
So, the "donor operation" has been undertaken and here is one of the front panel switches from this equipment, used to change the equipment AC line frequency up to 999Hz.
This push button mechanical switch is USED but in excellent condition.
OMRON (Japan) - Push Button Mechanical Switch
Made in Japan
Part number: A7BS-206 (3)
Material: Light Grey plastic
3x indentical switches in one housing
Each switch has digit count window, above this window is a "count down" button and below the window is the "count up" button
All three switches physically operate independently of each other
Output is encoded as BCD and available on 4x Gold plated solder contacts
DIMENSIONS:
Front flange: 31.95mm width x 24mm height
Four snap fit fingers sit behind this flange - push into the panel cutout and the switch it locked in place
Body: 30.15mm width x 22mm height x 32.15mm depth (including the rear contacts)
COSMETIC CONDITION:
USED
Clean and completely undamaged physically
NO cracking or broken plastics
ALL four fingers are in sound condition
Each switch solder finger has been cleaned of any previous wiring
Each push button on each switch has been checked, nice positive "feel" and the digit displayed in the window moves nicely in response
TESTING:
Fully functioning immediately prior to the equipment being "operated on", only the physical action of the switch has been checked since removal - I have no reason to believe anything might be wrong with this switch.
Stored and supplied in a clear sealed plastic packet
