An emergency stop switch mechanism for a robot which can take an emergency position when an external operation force is released and when a strong external operation force is applied. When the robot operation is started, a main lever La is pushed down from the OFF state with a normal external operation force. Since an elastic biasing force S2 is sufficiently larger than S1, a second ancillary lever Lc is pushed by a plunger PL and is turned downward together with a first ancillary lever Lb. A movable contact element ME of a contact mechanism section CM is moved to the ON position by the second ancillary lever Lc, so that the ON state (motion permitting state) is established. If emergency stop becomes necessary, the pressure of the main lever La is released from this state, or a specially strong force is applied to the main lever La.
