摘要： An electric on-off switch which may optionally include a thermal trip including a bimetal strip.The switch comprises a housing having therein a stationary contact which is engageable by a movable contact carried by a contact spring. The spring is actuated by a mechanism including a tiltable operating lever which carries a release lever. An operating cam is provided on the release lever for depressing the contact spring and causing the movable contact to engage the stationary contact.When the switch includes a directly or indirectly heated bimetal strip, the release lever is pivotally carried by the operating lever which carries a torsion spring. The torsion spring biases the release lever into contact with a set screw secured to the bimetal strip and also urges the cam into contact with the contact spring. A pivotally mounted, elongate lever is preferably disposed between the set screw and the release lever. When the switch is tripped due to excess current the bimetal strip bows and displaces the cam from the contact spring and thereby allows the contacts to separate.The switch may be provided with a U-shaped mounting frame which can be oriented to one of two different positions. Also two or more switches may be ganged together and held together by a U-shaped bracket. A common rocker may be connected to the operating levers of the switches.

摘要： A multipole excess current switch composed of a plurality of single pole excess current switches each arranged to be placed in series in a respective circuit to be protected, each single pole switch including a U-shaped bimetallic member connected to conduct the current through such circuit and to undergo a change in shape when conducting an excess current, and a spring loaded switching arrangement arranged to open the switch in response to movement of the bimetallic member, and the switching arrangements of all of the single pole switches being mechanically connected to trigger operation of the spring loaded switching arrangements of the other single pole switches when one of the switches opens in response to an excess current through its associated circuit. Advantageously, the U-shaped bimetallic member is composed of a plurality of bimetallic strips disposed adjacent one another, but separated from one another by insulating material, with each strip being provided with a slot that divides it into two legs and the strips being interconnected to place all of the legs of the several strips in series, thereby establishing a high resistance path that makes the bimetallic member responsive to low current levels.

摘要： A push button operated circuit breaker with thermal tripping by way of a bimetal strip includes an angled contact bridge which is mounted within a switch housing to be freely pivotal and is urged in a tripping direction by a tripping spring against a contact lug of the bimetal strip projecting laterally for engagement with a contact piece of the contact bridge. The circuit breaker further including a connecting arm which is coupled for movement with the bimetal strip. The cylindrical exterior surface of a drum-shaped rotary body lies against the connecting arm and thus creates a kinematic connection between the rotary body and the connecting arm. When the switch housing is fully assembled, the drum-shaped rotary body is operative as an adjustment eccentric which is externally manipulatable by way of a hexagonal recess so as to adjust the tripping characteristic of the circuit breaker.

摘要： An overload protection switch having a push button for manually initiating actuation of the overload protection switch and a movable contact member forming a switching path and having at least one fixed contact. There is a lockable trip mechanism actuated by the push button for controlling the movable contact member during actuation of the overload protection switch and a bimetal element which includes a locking lever pivotal into a locking position and pivotal into its unlocking position. A trip slide is articulated to the movable contact member and is charged in a turn-off direction. The trip slide is additionally supported in its path of movement by a housing groove at a counterslope fixed to the housing. An essentially wedge-shaped inner angle is formed to reduce friction forces at the locking lever and produce a lower tripping force at the bimetal element.

摘要： A push button-actuated overload protective circuit breaker with bimetal cutout comprises a housing between the sidewalls of which two contact segments are held in position, and a push button and a pressure spring associated therewith are guided for longitudinal displacement therebetween. The ends of the contact elements which protrude from the housing are devised as plug-in prongs arranged in parallel with each other. In order to provide a circuit breaker of such small size that it can be plugged into a flat-shape fuse female plug socket, the contact elements are provided in a middle zone thereof, each with a step-like bend the height of which corresponds to about half the height of the interior space in the housing. The bent contact ends then come to rest against the opposite internal surfaces of the housing sidewalls.At one of the contact ends of a first contact element there is fastened a bimetal snap spring with one side thereof and extends transverse to the direction in which the contact elements extend. This bimetal snap spring has a slewable end which overlaps the second contact element and is biassed into contact with the latter when in rest position. The push button is provided at its inner end with a separating wall which is adapted for sliding between the slewable end of the bimetal spring and the contact end of the second contact element when the circuit breaker is released.
