Abstract: A flexible conductor which connects the movable rod side of a circuit breaker and a movable side connection conductor is devised to miniaturize the circuit breaker.

Abstract: The apparatus (10) includes a depressible member (20), a first membrane (30), and a second membrane (40). The depressible member (20) has an unactuated condition and an actuated condition. The first membrane (30) is connected with the depressible member (20). The first membrane (30) resists movement of the depressible member (20) from the unactuated condition to the actuated condition. The first membrane (30) further provides an increasing return force (91) urging the depressible member (20) to the unactuated condition as the operator moves the depressible member from the unactuated condition to the actuated condition. The second membrane (40) resists movement of the depressible member (20) to the actuated condition. The second membrane (40) further provides an increasing return force (92) to the depressible member (20) as the operator moves the depressible member from the unactuated condition to the actuated condition.

Abstract: A plurality of fixed contacts and a movable contact are provided on a substrate so that opposite contacts form a unit switch. A holding plate having a holding corner is mounted on the substrate, and an operating plunger having a plurality of radially extending arms is slidably mounted in a hole formed in the holding plate, and rotatably held in the holding corner so as to be tilted about the holding corner. A plurality of projections are formed on the underside of the plunger, each of the projections is provided corresponding to the movable contact.
