  • Patent number: 6114638
    Abstract: A rotary switch device in which fixed contacts are fixed to one face side of a base member made of a synthetic resin, contact plates in a ring shape are floatingly held by a rotor disposed opposed to the one face side of the base member, movable contacts capable switching the connection and disconnection to and from the fixed contacts in accordance with the rotation of the rotor are integrally formed at a plurality of places spaced from each other at circumferential intervals on the contact plates, and sliding faces capable of being brought into slide contact with the movable contacts are formed on the one face of the rotor side of the base member, along a plane orthogonal to the rotation axis of the rotor. The sliding faces are formed in the base member so as to avoid the loci which are drawn by portions of the movable contacts to be brought into slide contact with the fixed contacts in accordance with the rotation of the rotor.

  • Patent number: 5814775
    Abstract: A rotary switch includes an insulative first housing with first and second terminals, and an insulative second housing. The first housing has a top wall with an axial hole formed therein, a bottom wall with a socket-like cavity formed therein, an upright side wall lateral to the top wall, and a shaft journalled in the axial hole to rotate stepwise relative to the top wall. The first terminals have first connecting end portions extending outwardly of the upright side wall. The second terminals have second connecting end portions extending axially from the axial hole and outwardly of the bottom wall at a distal end thereof relative to the upright side wall. The second connecting end portions are longer than the first connecting end portion so that each of the second connecting end portion forms a protracted intermediate segment and a connecting end segment for electrical connection. The second housing is molded around portions of the protracted intermediate segments of the second terminals.

  • Patent number: 4608466
    Abstract: Am improved switch is set forth. The switch has an insulating housing supporting a plurality of flexible contacts fashioned from a first conductive material selected to impart flexibility and spring action to the contacts. Accordingly, the contacts can be biased to engage and maintain contact with the switch rotor which is manipulated to produce the desired switching. Welded to each contact is a terminal connector extending to the exterior of the housing for connection to wires. The terminal connectors are fashioned from a second conductive material selected for strength and durability to prevent breakage.

    Abstract: A rotary switch comprising a body supporting a shaft and a plurality of spaced apart stationary contacts located around the shaft. The shaft is supported for axial and rotary movement and carries a contact means for engaging the stationary contacts as the shaft is rotated to different angular positions. A stop fixedly supported by the body and a disc connected to the shaft and having two sets of teeth located in two different planes are provided for requiring the shaft to be moved axially and angularly in order to allow it to be rotated to the different angular positions for causing the contact means to engage the stationary contacts.

  • Patent number: 4236104
    Abstract: The switch of the invention is a double deck type rotary switch having a position deck for detecting a home position and means for determining each position of the switch relative to the home position. A switching deck, rotated together with the position deck, selectively applies operating voltage to a plurality of operative devices, such as sprinkling valves.The system incorporates a microprocessor to control a motor for driving the rotary switch to a commanded position. The position deck signals the microprocessor as the deck reaches the predetermined position and the processor provides a delay before applying voltage to the switching deck, insuring that good load contact is made, so that arcing is avoided. The switching deck makes its load contact a few degrees ahead of the position deck in order that the load contacts for the work voltage are in the center of their terminal spring clips before the microprocessor is signaled that the predetermined position has been attained.
