Hälfte defekt, nicht zuverlässig

Von 8 bestellten Kontakten waren 4 bereits bei der Ankunft defekt (Widerstand gemessen mit Multimeter). Der Kontakt scheint stecken zu bleiben. Erschütterungen scheinen es bei manchen Kontakten temporär zu lösen, allerdings nur bis der Magnet angehalten wird..dann steckt es wieder.
Habe einen der Funktionierenden verbaut, hielt aber nur für einen Tag und war dann auch defekt.

Ansonsten würden sie vielversprechend wirken. Kommen mit Klebestreifen auf beiden Teilen und hätte auch Öffnungen zum Schrauben.
