Modular capacity-regulating and voltage-regulating combined switch

The utility model discloses a modular capacity-regulating and voltage-regulating combined switch. Including a base, a first groove is formed in the top of the base; a switch shell is movably connectedto the top of the base, a plastic insertion rod is fixedly connected to the bottom of the switch shell, three partition plates are fixedly connected to the top of the inner wall of the switch shell,four identical cavities are formed between the three partition plates and the switch shell, and a sleeve is embedded in the top of the switch shell. According to the utility model, the push rod is pushed downwards through the handle; the bottom end of the push rod is fixedly connected with the contact head. When the push rod moves downwards, the contact head is driven to move downwards together, through cooperation of the ball groove and the ball, the ball is driven to roll downwards together when the push rod moves downwards, and therefore the stability of vertical movement of the push rod isimproved, and when the con
