Ex 1980's audio equipment (removed from DENON PMA-710 Amplifier front panel)
Please look at the photographs and read the description below to try and ascertain if this button assembly may suit your own equipment.
DENON
Front Panel Switch Actuator System With Button
Description (attempt):
These are special to DENON, the rectangular silver metallic button sits within a rectangular rear section that has a spring inside it. The rectangular section has a flange at the front, this is GLUED to the rear of the front panel. This flange also has a hole for the power on led.
The switch to be activated (NOT included) sits back from the front panel and this actuator system acts as an extended finger to push the switch on and off, the spring provides positive return of the button.
On the DENON equipment this was removed from, this button is used for the main power on-off button (and indicator) - it may be that other DENON equipment uses this same system.
Dimensions (Digital calipers):
Flange: 32mm x 30mm OD
Silver button: 18mm x 10mm OD
Rectangular section (rear) : 21.6mm x 14mm OD
Button "throw" (distance between fully recessed and fully extended) 8.5mm
90% plastic construction with the only exceptions being the metal button and internal spring
CONDITION:
Used but very clean.
NO damage to the button or mechanism - operates smoothly
Since removal, I have now carefully packed and sealed this button assembly in plastic to preserve the condition
