<p>PROBLEM TO BE SOLVED: To provide a reliable latch mechanism to be used for transmitting a signal to a system during the hot-line insertion of a printed circuit board. SOLUTION: A printed circuit board 112 includes a corner part 200, a switch member 204, a latch pin 206, and a pivotal latch main body 208. The latch main body 208 is provided with a first edge part 212 having a cooperative structural body 214 for transmitting pivotal movement by a signal interacting with the switch member 204. A second edge part 216 of the latch main body 208 is provided with a structural body to be inter-engaged with a chassis, for example, an arm largely extended in the width direction from the edge part of the printed circuit board so that the latch main body 208 can be selectively locked in the closed position where it is butted to the chassis or lock-released in the open position where it is removed from the chassis according to the pivotal movement of the latch main body. When the latch main body is in the closed position, a hook 226 is selectively butted and engaged against the latch pin 206.</p> |
