A deadman switch mechanism and a teaching operation panel equipped with the deadman switch mechanism, in which possibility of losing a safety function is low even if failure happens in a contact or other elements of a circuit. When an operator grips at least one of grip levers (GL1; GL2) with normal force, the grip levers turn around axes (AX4; AX5), shoulder portions (SD1; SD2) abut on slave levers (SL1; SL2) and turns the slave levers connected by a link (LK) around an axis (AX3) in the direction denoted by an arrow B, simultaneously, so that switches (SW1; SW2) are turned into an ON-state, simultaneously. Then, two circuits including those switches, respectively, output ON-signals independently and these signals are subjected to AND process, to allow the robot to operate. In an emergency, when an operator releases gripping of the grip levers (GL1; GL2), the slave levers (SL1; SL2) turn in the direction denoted by an arrow A, simultaneously, so that the switches (SW1; SW2) are brought into an OFF-state, simultaneously, and the robot stops immediately.

[ What is claimed is:] [1.] A deadman switch mechanism for an emergency stop of a robot, comprising:a plurality of switches each having an ON-state and an OFF-state;switching means for switching said plurality of switches between the ON-state and the OFF-state; andmeans for outputting a signal for allowing a robot to operate on the condition that all of said plurality of switches are in the ON-state,wherein said switching means includes at least one handling member having an external-operating-force receiving portion exposed outside, a handling-member supporting member for supporting said at least one handling member so that said at least one handling member moves in accordance with an external operating force applied to said external-operating-force receiving portion, and a switch turning member linked with all of said at least one handling member, for simultaneously turning said plurality of switches to the ON state/the OFF-state.
