Claims (1)

[Claims for Utility Model Registration] A switch equipped with four contact switches corresponding to four directions (up, down, left and right), and four contact switches corresponding to four diagonal directions, and which includes up, down, left and right contact switches and a diagonal contact switch. In the controller, the signals output from the upper, lower, left, and right contact switches are output as they are, while the signals output from the diagonal contact switches are output from the upper, lower, left, and right contacts located on both sides of the controller. A contact output circuit for a controller, comprising a signal control means formed by a logic circuit that outputs the output signals of a contact switch as they are only when both output signals indicate the open state of the contacts.
