Abstract
A switch is coupled to a switch support and includes a push button, a lock assembly, a tab, and a hook. The lock assembly includes an operation ring, which is rotated about the button between an unlock position to permit actuation of the button and a lock state to prohibit actuation of the button, and a lock ring, which is rotated integrally with the operation ring. When the operation ring is located at the lock position, the hook and the tab are arranged at the same position in a circumferential direction, which creates interference between the hook and the tab and blocks actuation of the button. When the operation ring is located at the unlock position, the hook and the tab are separated from each other in the circumferential direction, which avoids interference between the hook and the tab and permits actuation of the button.
