1. An electronic apparatus having a plurality of switch contacts and performing an operation in accordance with a switch signal from one of the plurality of the switch contacts, the electronic apparatus comprising:
- a control unit configured to control operation of the electronic apparatus in accordance with the switch signal,the switch contact comprising;
a detection contact;
a common contact shared by all of the plurality of the switch contacts; and
a movable contact making the detection contact and the common contact conductive by a user operation,wherein at least one of the plurality of switch contacts includes a plurality of the detection contacts, and each of the plurality of the detection contacts belonging to the at least one switch contact is shared by different other switch contacts, respectively, and at least one switch contact having the plurality of the detection contacts shares at least one of the detection contacts within the plurality of the detection contacts belonging to the switch contact, with a switch contact which does not lie adjacent to the switch contact and,wherein the control unit controls operation of the electronic apparatus in accordance with a switch signal from a switch contact among the plurality of the switch contacts, if all of the detection contacts belonging to the switch contact are made conductive with the common contact.

Abstract
At least one exemplary embodiment is directed to an electronic apparatus includes a switch contact and a control unit. The switch contact is constituted of a fixed contact and a movable contact. The fixed contact includes a plurality of detection contacts and a common contact. The movable contact can be moved to a contact/noncontact state. The control unit detects a signal generated when all of the contacts in the fixed contact are simultaneously made conductive by contact of the movable contact.
