You can get these Apem switches in better quality with the designation 1212A2. On the one hand, A means Argentum because the switch has silver contacts and lives much longer. Secondly, the contacts are accessible and can be bent outwards if there is not enough space behind the pedal. I don't see in your photo how the contacts are accessible.
