Insertion detection switch, connection apparatus and connector apparatus

摘要

An insertion detection switch is provided for detecting that a recording medium on which electrode pads are formed is inserted. The insertion detection switch has a first contact and a second contact that are electro-independently arranged on an insertion trajectory of one of the electrode pads of the recording medium. The first contact and the second contact are electrically connected via one of electrode pads when the recording medium is inserted to a predetermined installation position.
