This ZLDC04B limit switch are for China only and handled by AP facility. It has a plastic housing, 20mm conduit threads, 1NO / 1NC make before break contacts and top pin plunger.
I have two options:
GLDA01B limit switch. It is the same as above but with a 1/2-14 NPT conduit thread and 1NO / 1NC snap action contacts.
GLDB01B limit switch. It is the same as above but with a PG 13.5 conduit thread and 1NO / 1NC snap action contacts.
