Default Spdt momentary tactile switch help needed

Spdt momentary tactile switches
Some are now broken
Could anybody identify a source for a replacement from the attached photo?
Not really vintage (2007) but I would like to keep this alive if at all possible as it's a great piece of kit

are they definitely SPDT? I've never seen any like that in a 6x6 tact switch

Any of the major component suppliers - CPC, RS etc - look for Tactile Switches.

Be careful, the height is important - some places define height to be total including the button, others list the button height seperately.

I am assuming you think they are SPDT because they have 4 mounting legs - they are more likely SPST as two legs are electrically paralleled for each contact.
