As removed from a Pioneer CT-506 Cassette Recorder/Player but these buttons MAY suit use with other Pioneer products also
PIONEER - Cassette Deck Model CT-506 4x front panel buttons
These are the "push on" buttons used to activate
DOLBY NR
TAPE SELECTION (3)
They are metallised (chrome) plastic
NO cracks
NO significant discolouring
These have all been cleaned and polished up - not perfect but in very good condition
Great when an existing button has broken or someone has pulled it off!
OR
If the thought was to use these in other equipment (probably also PIONEER), the dimensions are:
11mm wide x 11mm depth x 5.5mm height (thickness)
The rear is a push fit slot for the switch shaft, 7.2mm wide x 1.25mm thick which means it "takes" a wide/thin shaft finger
