Abstract: A disconnect mechanism for an electrical system that is integrated with the enclosure of the system, yet includes an external handle for closing and opening the electrical circuit. The invention utilizes the system's circuit breaker to switch the current on or off, eliminating the need for a separate external disconnect. Moving parts are limited to an external actuating handle connected by a shaft to an actuating arm, which has an opening whose inner edges press against a pin connected to the circuit breaker to trigger its movement between the on and off positions. Automatic tripping of the circuit breaker during a system overload moves the external handle to the off position, furnishing visual evidence of the systems working status. A watertight seal maintains the integrity of the electrical system's enclosure.

Abstract: An electrical switch having a switching lever for actuating a slide which receives at least one contact bridge, and having an enabling slide which is active in the inserted position. The technical problem is to provide a switch whereof the switching lever only enables effective switching once the enabling slide is in the inserted position.

The enabling slide has a bearing point for the switching lever which is active in the inserted position. A push rod (24) is guided linearly, is moved by the switching lever and comes into engagement with a profiled guide of the slide. In the ON position, on pivoting into a latching step, the slide and the contact bridge perform a transverse movement on the fixed contacts of the contact springs.

Abstract: A micromechanical electrostatic relay has a base substrate with a base electrode and a base contact piece. The relay also has an armature substrate with an armature spring tongue that curves away from the base substrate, and an armature electrode and an armature contact piece. When a control voltage is applied between the two electrodes, the spring tongue unrolls on the base substrate and thus closes the contact.

In order to avoid undesired transverse arcs of the spring tongue, the compressive strain layer is subdivided into strips by slots in a longitudinal direction of the spring tongue. A tensile stress layer applied in surface-wide fashion over the strips and slots reinforces the compensation effect.

Abstract: An object of this invention is to provide a lever operating device for a switch in which the distance between a lever and an actuating element is reduced. According to the present invention, a lever is swung, a transmission member is swung, so that an actuating element is moved to operate a switch. In this connection, arms of the transmission member are made equal in length to each other, so that, as the lever swings, an engaging pin swings the same distance as the actuating element moves. Hence, by setting the distance between the shaft pin and the engaging pin of the lever to the movement distance of the actuating element, the latter can be moved a predetermined distance required for operating the switch, even when the arm of the transmission member is short.

Abstract: A three-position floating beam armature switch includes a hollow housing, in which a floating beam armature is resiliently biased toward the closed top of the housing. An operator member is carried by the housing to apply a predetermined force to the armature; so that a first end of the armature initially moves toward the bottom of the housing by pivoting the armature about its second end. Continued application of additional force by the operator member, causes the armature to pivot about the first end; so that the second end then moves toward the bottom of the housing. With both the first and second ends at the bottom of the housing, the third position of the switch is attained. Release of force by the operator member allows the floating beam armature once again to be biased toward the top of the housing to the initial position.

Abstract: An equipment unit latch and an associated switch arrangement are advantageously employed to generate an action initiation signal upon initial movement of the latch toward physically removing the equipment from an equipment frame but prior to any movement of the equipment unit in an equipment frame in which it is inserted.

In a specific embodiment of the invention, the switch includes a light emitter and a light detector. Light from the emitter is inhibited from reaching the detector by the latch when the equipment unit is fully inserted in the equipment frame and the latch is in a closed position.

Abstract: A known switch is mounted on a base of a switch actuator assembly. When the switch is to be actuated, an input shaft and switch actuator member are rotated together relative to the base. A helical return spring urges the input shaft back toward the initial position. When the input shaft and switch actuator member have been rotated together to an actuated position, the switch is actuated and the switch actuator member engages a stop surface. During continued rotation of the input shaft from the actuated position to an overtravel position, a pin connected with the input shaft moves away from one end of a slot in the switch actuator member. A helical overtravel spring is deflected along with the return spring. Deflection of the overtravel spring urges the switch actuator member and input shaft back toward their initial position relative to each other.

Abstract: An equipment unit protection switch from an in-service equipment unit to a standby equipment unit is realized prior to any movement of the active equipment unit about to be removed from an equipment frame in which it is inserted. This is achieved by advantageously incorporating apparatus for generating an equipment unit removal indication signal that enables a controller to anticipate the removal of the equipment unit from the equipment frame. To this end, the equipment units employ an equipment unit latch and an associated switch to generate the equipment removal indication signal. Initial movement of the latch causes the equipment unit removal indication signal to be generated prior to any movement of the equipment unit in the frame in which it is inserted.

The operating lever device is arranged such that any one of a plurality of rod members (22) which are inserted slidably while they are constantly urged upward into the device body (10) can be pushed down by the tilting of a lever (20) so as to rotate either a first shaft (23) or a second shaft (24) through a retaining member (27) or (28) held in contact with the lower end of the rod member (22). Thus, the angle of inclination of the lever (20) can be detected precisely by either one of rotational angle sensors (25, 26) mounted on at least one end of each of the first and second shafts.

Abstract: An equipment unit protection switch from an in-service equipment unit to a standby equipment unit is realized prior to any movement of the active equipment unit about to be removed from an equipment frame in which it is inserted. This is achieved by advantageously incorporating apparatus for generating an equipment unit removal indication signal that enables a controller to anticipate the removal of the equipment unit from the equipment frame. To this end, the equipment units employ an equipment unit latch and an associated switch to generate the equipment removal indication signal. Initial movement of the latch causes the equipment unit removal indication signal to be generated prior to any movement of the equipment unit in the frame in which it is inserted.
