    Abstract: An electrical switch has a fixed contact and a moving contact arranged for movement between an ON position in contact with the fixed contact and an OFF position out of contact with the fixed contact, and an operating member for operating the moving contact. A spring co-acts between the operating member and the moving contact and resiliently biases the moving contact towards each of the ON and OFF positions through an over-centre action of the spring. An end piece is fitted at each end of the spring, which has a formations for example, a groove, for pure rotary engagement with a part, for example a pin, movable with the operating member or moving contact for imparting resilient action upon the operating member or the moving contact.

    Abstract: A quick-break switch in which, for switching-over purposes under the spring force (1) of a switching element, the two individual wedge faces of a wedge surface are felt. In order to render the pressure point more perceptible, in particular when the switch is manually operated, the wedge faces are curved. These curves can also help to improve the switching behavior of the switch with respect to the switching process and contact-making.

    Abstract: A snap switch having spring a spring energy store and wedge profile. In conventional switches, the wedge profile was attached to the end of the contact arm, which forms the moving switching element. Heating of the contact arm due to large, switched electrical currents results in heating of the wedge profile and thus to a possible retardation of the switching, which, in turn, contributes to an additional heating of the wedge profile. The wedge profile is positioned where a low heat effect is expected. Thus, the wedge profile is seated under pretension at the switching element, where the contact arm forms a single sheet metal part whose one end senses the wedge profile.

    Abstract: A resetting device coupled to a thermostat which has a resetting pin actuated by depressing the same, comprises a body arranged to be movable towards and away from the resetting pin; a propelling device for launching the body in the direction of the resetting pin for depressing the resetting pin by the body in an impact-like manner; and an operating arrangement movable into an actuating position for actuating the propelling device. The resetting pin is freely movable subsequent to the impact-like engagement by the body, irrespective of the momentarily-assumed position of the operating arrangement.

    Abstract: An electric snap-action switch is disclosed having a movable contactor with oppositely inclined camming surfaces meeting at an apex on the top thereof. The contactor is centrally biased upwardly from below and cammed downwardly from above by a laterally movable operator traversing the inclined camming surfaces such that the contactor snaps laterally against vertical stationary contacts as the apex is crossed by the operator. The invention includes fulcrum means effective to stop the downward movement of the contactor before the operator crosses the apex whereby a moment arm is formed from a fulcrum to the point of operator-contactor engagement such that further movement of the operator towards the apex effectuates a torque on the contactor to pivot the contactor about the fulcrum to positively break any welds or other frictional attachments between the contacts without relying on the stored energy of the carrier biasing means, thereby affording a switch having little possibility of failure in an "on" position. The inclined camming surfaces of the contactor may be formed with compound slopes to assure constant operator pressure prior to trip point as the contactor pivots and increases the angle of inclination of the camming surface traversed by the operator. Specific embodiments of a double-pole single-throw trigger switch and a double-pole double-throw toggle lever switch are disclosed.
