A push button locking switch is provided to prevent suspension of an electric device by preventing an off-switch from being pushed by mistake. A push button locking switch includes an on-switch(20-2), an off-switch(200-1), and a locking pin(510). The off-switch(200-1) is pushed while the on-switch(20-2) is fixed. The locking pin(510) formed on the off-switch(200-1) is locked. If the locking pin(510) is moved from a left side to a right side and the off-switch(200-1) is not pushed, the on-switch(20-2) and the off-switch(200-1) are interlocked with each other so that one of the on-switch(20-2) and the off-switch(200-1) is pushed for preventing an electric device from being operated.
