    • The disclosure relates to a battery pack, comprising a casing (100); a built-in circuit (200) disposed inside the casing (100); a consumable component (300) disposed inside the casing (100) and connected in series to the built-in circuit (200), wherein an opening (110) corresponding to the consumable component (300) is provided on the casing (100); a safety switch (400) disposed inside the casing (100), wherein an on/off of the safety switch (400) controls a connection/disconnection of the built-in circuit (200); and a cover body (500) disposed corresponding to the opening (110), wherein the cover body (500) has a first state in which the cover body (500) is capped at the opening (110), so that the safety switch (400) is switched on and the built-in circuit (200) is connected, and a second state in which the cover body (500) is detached from the opening (110), so that the safety switch (400) is switched off and the built-in circuit (200) is disconnected. In the embodiment of the disclosure, the battery pack can be used normally when the cover body (500) is capped at the opening (110) and the battery pack is tightly sealed, and therefore, the safety accident caused by the seal failure when the battery pack is used can be avoided; and the built-in circuit (200) is disconnected when the cover body (500) is detached from the opening (110), and therefore, the safety accident caused when the built-in circuit (200) is forgotten to be disconnected during maintenance of the consumable component (300) can be avoided.

    • It is an object to provide a switch that can respond to opening and closing of medium load and that has small operating sound. There is provided a switch including a movable contact piece (40) having one end as a supporting point of turn and the other end arranged with a movable contact (43); a turning member (30) having the other end as a supporting point of turn; a coil spring (50) halving one end (51) locked to one end of the turning member (30) and the other end (52) locked to an intermediate portion of the movable contact piece (40); and a push button (80) being supported to be slidable in an up and down direction and for pushing down the one end of the turning member (30) with a lower end face (82); the movable contact piece (40) being inverted by pushing down the one end of the turning member (30) with the push button (80) so as to make the movable contact (43) approach and separate to and from a fixed contact (28). In particular, the turning member (30) includes a position regulating portion (31) that is brought into contact with the coil spring (50) when the movable contact piece (40) is inverted and that brings the movable contact (43) into contact with the fixed contact (28) while maintaining a contact state with the coil spring (50).
