PROBLEM TO BE SOLVED: To prevent damage to a push switch by suppressing a momentary frictional force to a swing fulcrum of a movable contact piece of the switch when an opening/closing body is closed. SOLUTION: A pressing structure of the switch in a lock comprises a trigger provided in a case so as to project its tip and an interlocking piece disposed in the case so as to be positioned between the inner end of the trigger and the push switch. When the opening/closing body is closed, a collision of the tip of the trigger with a door frame side moves the trigger backward against an energizing force of an energizing means, and the interlocking piece rotates by a required angle interlocked with the trigger to press the surface of the movable contact piece of the push switch, thereby actuating the push switch. The interlocking piece is integrally provided with an elastic pressing piece of which the hook-shaped pressing portion can be displaced to the inner side by properties of a material, and when the opening/closing body is closed, the trigger moves backward and the interlocking piece is interlocked, so that the bent tip of the hook-shaped pressing portion presses the surface of the movable contact piece.
