  • Patent number: 5990424
    Abstract: A breaker device is provided in which a lever can be locked in specified positions with an improved reliability and unlocking can be easily effected. A slider (60) carried by a lever (30) and a panel (22) of a casing (20) define a locking mechanism of the device. When the lever (30) is in a specified rotation position, the slider (60) and the panel (22) are engaged with each other to lock the lever (30) in that position. An unlock portion (62) for unlocking the locking mechanism is provided in a position to be covered by a handle portion (32) of the lever (30). Since this unlock portion (62) is protected by the handle portion (32), a tool or the like cannot come into contact with or strike the unlock portion (62). On the other hand, if a finger is placed on the handle portion (32) to rotate the lever (30), the tip of this finger is located at the underside of the handle portion (32), so that the unlock portion (62) can be easily operated.

  • Patent number: 5508480
    Abstract: A modular electrical switch provides a wiping or shearing action upon closing and opening thereof. A contact carrier disposed within a housing linearly carries a movable contact into engagement with a stationary contact. The contact carrier is guided by movable slide plates disposed on either side thereof and movable along with the contact carrier as a contact assembly. The guide plates also provide pivot recesses for pivot bosses of the contact carrier. The contact carrier is constrained to linear motion up to the point of contact between the movable contact and the stationary contact by a cam trace in the housing. After contact between the movable contact and the stationary contact, the contact carrier reaches a pocket defined by the cam trace, ceases linear movement and upwardly pivots to provide a wiping action between the movable contact and the stationary contact.

  • Patent number: 4538040
    Abstract: A pair of separate electrical switches are disclosed, each including a fixed contact supported by and electrically connected to a printed circuit board, and a movable contact comprising a deflectable portion of a strip of springy, conducting material. A single such strip is supported by and electrically connected to terminals of the circuit board in a central portion of the strip, the opposite end portions forming the movable switch contacts. A pair of push rods are carried by spaced, flexible, rubber boots which position the push rods and move them axially to urge the respective ends of the strip to a deflected position which moves one strip end away from the associated pin, opening a normally closed switch, and moves the other strip end to contact the pin, closing a normally open switch. The electrical and physical configuration of the switches is particularly suited to use as test and reset switches of a ground fault circuit interrupter device, in which context the invention is disclosed.

  • Patent number: 4517421
    Abstract: An array of fluid filled cells bearing symbols on their faces transmit applied pressure or displacement to a remote end of the cell which have a mating array of electrical switches normally maintained in an open position. Pressure or displacement of the upper surface of the cell is transmitted to the lower surface to operate (close) the switch. Upon removal of the applied pressure, the cell returns to its initial position. A second embodiment of the invention shows an entirely modular key formed from a rubber-like material or from a self-skin foam material such as a polyurethane. The modular key has the keyface, body and switch elements formed integrally so that the keys can be added to a premated matrix. Still another embodiment of the present invention shows a totally sealed electronic terminal or device which is specially adapted to accept the modular keys.

  • Patent number: 4506118
    Abstract: A multiple position switch includes a housing containing a plurality of membrane switches located in a predetermined pattern. A spring-based, normally centered actuator is mounted in the housing for selective movement to actuate one of the switches. A finder plate is attached to the housing and has a notched circular opening in alignment with the plurality of switches. The actuator is guided to a selective switch location by its engagement with one of the finder plate notches when the actuator is moved in close proximity to a selective switch location.

  • Patent number: 4481585
    Abstract: A plurality of electrical load switches of the type operable to at least two operating conditions by the actuation of an operating member are connected in respective motor vehicle load circuits and are mounted in a switching unit having an actuating mechanism for actuating the switch operating members that is selectively locatable in each of a plurality of switch operating positions in each of which it is in register with an operating member. The switching unit is controlled by a microprocessor that effects the locating of the actuating mechanism in the switch operating position in which it may actuate the operating member of a load switch selected to be operated and the operating of the actuating mechanism when so located in response to function select electrical signals that indicate the load switches selected for operation.

  • Patent number: 4476449
    Abstract: An actuator for selectively actuating a circular array of electric switches. The actuator includes a molded plastic rotor part that contains particles of magnetic material. One portion of the rotor is magnetized to provide a permanent magnet that is effective to attract a switch actuating arm that is pivoted to the rotor. Another tubular portion of the rotor is magnetized to provide the rotor of an electric stepper motor. The stepper motor rotates the rotor to various positions. The arm can be attracted by an electromagnet and pivoted to a position in which it operates one of the circular array of switches.

  • Patent number: 4403121
    Abstract: A plurality of individual electrical load switches each having an operating tab are so mounted and oriented that the operating tabs extend toward a central axis to define a circle substantially normal to the central axis and operate substantially in the direction of the central axis. An operating arm having ends thereof arranged to be brought into register with each operating tab at mutually exclusive angular positions is normally tilt mounted in a first direction upon a rotor that may be positioned in selected ones of a plurality of angular positions by a step motor. Upon one end of the arm being brought into register with a switch operating tab, the arm is tilted in the opposite direction to effect the operation of the operating tab with which the one end thereof is in register to place the corresponding individual electrical load switch in a selected circuit condition.
