Patent number: 4434339Abstract: Disclosed herein is a mounting frame equipped with a decorative plate, for mounting a switch or the like. The mounting frame includes a decorative plate having a through-hole formed thereon so as to mate with a sleeve which is step-wise formed at the upper portion of a switch, a pilot lamp or the like, and leg portions vertically suspended from the lower end portions on both sides of the decorative plate. When the sleeve is fitted into the through-hole while the inner side surfaces of the leg portions or a bridge interconnecting the lower portions of both leg portions are anchored to the corresponding outer side surfaces of the switch, the pilot lamp or the like, the switch, the pilot lamp or the like can be mounted to, and dismounted from, the mounting frame in one-touch operation.Type: GrantFiled: September 28, 1982Date of Patent: February 28, 1984Assignee: Nihon Kaiheiki Kogyo Kabushiki KaishaInventor: Shigeo Ohashi

Patent number: 4405843Abstract: An improved anti-static switch lock of the type having a key-operated plug rotatably located within a lock barrel, A nonconductive switch adapting hub connected to the lock barrel and a switch affixed to the hub, actuable upon rotation of the plug. The improvement consisting of a hub and plug design wherein the hub is connected to the lock barrel by resilient legs which engage an annular shoulder within the barrel and the plug extends from the barrel such that it prevents the legs from disengaging the shoulder. A biasing means interconnects the hub and one of the hub legs to bias the rotation of the plug and the switch to a desired position.Type: GrantFiled: July 16, 1981Date of Patent: September 20, 1983Assignee: The Eastern CompanyInventors: Stanley C. Wolniak, Elbert M. Spencer, Ronald L. Brown

Patent number: 4398073Abstract: A fastening device which permits snap-in assembly of a switch to a panel or receiving member includes a resilient latching member connected to the switch housing and adapted to engage a shoulder of the receiving member. A second resilient member serves to urge the resilient latching member into contact with the shoulder. In one embodiment of the invention, the switch housing is inserted into a receiving portion of a control panel and a connector carries at least one resilient latching member adapted to engage a shoulder on the receiving portion. In this embodiment, the connector and panel cooperate to retain the switch.Type: GrantFiled: September 25, 1981Date of Patent: August 9, 1983Assignee: ITT Industries, Inc.Inventors: Jakob Botz, Rolf Feger, Erich Mutschler, Hubert Spazierer, Adam Weber

Patent number: 4385220Abstract: A dynamoelectric machine in the form of an induction motor includes a pair of end shields for supporting a rotor assembly. At least one of the end shields is a die cast structure having a channel formed in it. The channel is sized to receive a protector for the motor. A bracket utilized in conjunction with the motor includes a spring for biasing the protector within the channel, and a mounting surface to which an external electrical switch is mounted. The bracket includes a pair of arms arranged to permit mounting of the bracket on the induction motor side of the end shield. Consequently, dimensional variations caused by end shield design or manufacture are eliminated and the effect of those dimensional variations on switch/actuator performance no longer is significant.Type: GrantFiled: September 13, 1978Date of Patent: May 24, 1983Assignee: Emerson Electric Co.Inventor: Robert F. Bischoff

Patent number: 4346360Abstract: A low profile reed keyswitch which includes a magnetically actuated reed switch. The reed switch is mounted parallel to the keyswitch base on a retaining fixture which resistively holds the body of the reed switch. The leads of the reed switch freely pass through the base where they are available for direct connection to an external circuit. A permanent magnet is carried in a plunger which is spring biased away from the reed switch. The reed switch is actuated when an operator depresses the plunger to move the magnet toward the reed switch.Type: GrantFiled: May 1, 1980Date of Patent: August 24, 1982Assignee: Litton Business Systems, Inc.Inventor: Mark J. Del Tufo

Patent number: 4346274Abstract: An assembly for switches of the type which are pushed into a receptacle by means of webs guided in grooves. On each guide groove one side wall is staggered backwards relative to the other side wall in the longitudinal direction. It is then possible to bring webs and grooves into contact by a vertical movement with respect to the direction of insertion.Type: GrantFiled: June 9, 1980Date of Patent: August 24, 1982Assignee: ITT Industries, Inc.Inventors: Erich Mutschler, Adam Weber
