Definitions
- the present invention relates to a card switch, and more particularly to a card switch that detects insertion / removal of a card.
- a card switch for detecting insertion / removal of a card is known, and is disclosed, for example, in Japanese Patent No. 2785891 (hereinafter referred to as “Document 1”).
- the card type switch described in this document 1 connects / disconnects a power supply to an indoor load based on an attachment / detachment signal output from the attachment / detachment detection means and an attachment / detachment detection means for detecting the attachment / detachment state of the door lock card key to the card case.
- -Power supply control means for shutting down is provided.
- the card case is formed by forming a bag-like portion having an opening on the front surface of a substrate attached to a wall surface. The card key is inserted into the card case through the opening of the bag-like portion.
- the attachment / detachment detection means is formed by using a micro switch having an actuator protruding into the card case. Therefore, in this card type switch, when the card key is inserted into the card case, the actuator is pushed by the card key and the micro switch is turned on to detect that the card key is mounted. In this card type switch, it is detected that the card key is taken out by turning off the micro switch.
- the thin card key cannot sufficiently push the actuator, and the micro switch may not operate normally. Therefore, it is conceivable that the top of the actuator protrudes beyond the track of the card key so that the actuator can be sufficiently pressed even with a thin card key.
- the card key insertion / extraction direction intersects the actuator movement direction. For this reason, when the top part of the actuator is protruded from the track of the card key, the pressing by the card key is not transmitted to the actuator, and there is a possibility that the actuator cannot be moved.
- the present invention has been made in view of the above points, and an object of the present invention is to provide a card switch that can normally detect card insertion / removal even when the card is thin.
- the card switch of the present invention includes a case having an insertion slot into which a card is inserted, and a detection unit that detects whether or not the card is inserted into the insertion slot, and the detection unit includes a switch.
- the switch includes a contact, a housing that houses the contact, and a lever that partially protrudes from the housing, and the contact opens and closes as the lever rotates. A part of the lever faces a track for inserting and removing the card, and the rotating track of the lever is along the insertion and removal direction for inserting and removing the card.
- the rotating track of the lever that opens and closes the contact is along the track for inserting and removing the card. For this reason, even if the tip of the lever is protruded from the track of the card to accommodate a thin card, the lever can be rotated by inserting the card. Therefore, in the present invention, card insertion / removal can be normally detected even if the card is thin.
