PROBLEM TO BE SOLVED: To provide a lever operation mechanism for a switch which reduces the cost and provides sure action despite of a simple structure. SOLUTION: When an operation lever 2 is swung so as to press down a presser member 7 against the elastic force of a spring, a presser projection 10 applies the downward pressurizing force on an inclined cam face 13 of a contact holder 11. This pressurizing force generates horizontal component force by the inclined cam face 13 so that the contact holder 11 moves horizontally against the spring force of a return spring 12. The contact holder 11 is guided and moved to a guide groove 16, the interval between fixing contacts 17, 18 is bridged by a movable contact 15, and a passing switch circuit is closed. |
