PROBLEM TO BE SOLVED: To obtain a contact pressure regulation mechanism for a switch capable of easily adjusting contact pressure of a contactor and being light in weight of a movable section. SOLUTION: The contact pressure regulation mechanism for a switch comprises a rotary shaft 6 for rotating in response to application or circuit breaking of the switch, a rotary shaft lever 7 for rotating by firmly being fixed on the rotary shaft 6, a connection link 10 connected with the rotary shaft lever at one end via an intermediate link 8 and supported by a movable bearing 9 at the other end, and a main circuit connection section 15 having an isolation rod 12, a wipe link 13, and contact pressure spring 14 and connected with an intermediate section of the connection link 10 at one end and connected with a movable contactor 3 of the switch at the other end. The main circuit connection section 15 connected with the connection link 10 moves in the separating direction of both contactors 2 and 3 by displacing the movable bearing 9 in order to adjust contact pressure of the contactor.
