Figures 6 and 9 are cross-sectional views taken along line A-A in Figures 2, 5, and 8, respectively, and Figures 4, 7, and 10 are Figures 3, 6, and 9, respectively. B- in the diagram
It is a sectional view taken along the B line. Also, Figures 2, 3, and 4
The figure shows the steady state; Figures 5, 6, and 7 show the state when the button is pressed and the trigger is pulled to turn on the electric circuit; Figures 8, 9, and 10 show the state when trigger 2 is turned on. After pulling the button, push the button deeper to show that the closed circuit state is maintained. In the figure, 1 is a switch body, 2 is a trigger, 4 is a stopper mounting member, 5 is a stopper for opening, 6 is a stopper for closing, 7 is a protrusion for stopping opening, 8 is a recess for closing, 9 is a recess for opening, 10 is a convex portion for stopping the circuit, and 11 is a spring.

スイツチ。 In a safety switch equipped with a switch body having a built-in contact portion for opening and closing an electric circuit via a trigger, an opening stopper fixed to a stopper mounting member movably attached to the switch body via a spring, and the stopper mounting a circuit-closing stopper integrally formed on the member; a circuit-opening stop convex portion formed so as to come into contact with the circuit-opening stopper at a position where the stopper mounting member is not displaced to prevent the trigger circuit; and a spring attachment. A circuit-closing recess formed so as to accommodate the circuit-opening stopper at a position where the stopper mounting member is displaced to the intermediate point and the final point against the force; A circuit-opening recess formed to accommodate the circuit-closing stopper and a stopper mounting member are formed so as to come into opposing contact with the circuit-closing stopper at a position displaced to a final point, thereby preventing the trigger from returning to rotation. A safety switch characterized by having a trigger having a protrusion for stopping circuit closing.
