MM System A device including a new type of Normally Closed (NC) switch called Rocking Switch that uses an external mechanical force to open.
A system called “MM System” containing a switch called “Rocking Switch” (1) capable of connecting its ON or OFF mode to a mechanical force acting on a part of it called “extension”.
The essential elements of this device are a battery source (3), a light source (2) and a Rocking Switch (1) having a swinging door (8) with an extension (10).
The Rocking switch (1) is connected to the battery source (3) and to the light source (2) that are in turn connected between them (FIG. 1).
In the embodiment in a container equipped with a traditional zipper, the extension (10) will be placed in such a way that by closing the zipper (21) the extension (10) will be moved and the Rocking Switch (1) will be opened, vice versa by opening the zipper (21) the extension (10) will come back in the rest position and the Rocking Switch (1) will be closed (FIG. 6).
SENSING DEVICE FOR SENSING THE POSITION OF A MOVABLE OBJECT
A detection device (18) for detecting the position of a moving object comprises a base (20); an arm (22) that is mounted rotatable to the base (20), wherein the arm (22) is rotatable around a first rotational axis (26) and has a free end (28) for contact with the moving object; and a sensor (24) that is configured to detect rotation of the arm (22) relative to the base (20), wherein the sensor (24) has a first part and a second part, wherein the first part moves with the arm (22), and the second part is attached to the base (20). The first part is a first component of a magnet (40) switch (42) pair, wherein the switch is an electrical switch (42) that is configured to be actuated by the magnetic field of the magnet (40), and the second part is another component of the magnet (40) switch (42) pair.
Neutral position limit switch head design with part reduction and improved reliability
A limit switch operating head includes a shaft rotatable in clockwise and counter-clockwise directions, a cam member supported on the shaft and that is rotatable in the clockwise and counter-clockwise directions responsive to rotation of the shaft, and a follower actuated by the cam member responsive to rotation thereof, with the follower including a pivot pin, a lever portion pivotable about the pivot pin, and a rolling pin mounted to the lever portion and in contact with the cam member. An actuator member contacts the lever portion and translates linearly in a first direction or second direction responsive to pivoting thereof. The rolling pin moves along a profile of the cam member upon rotation of the cam member so as to cause the lever portion to pivot, with the actuator member linearly translating in the first direction or the second direction responsive to the pivoting of the lever portion.
Rotational over travel protection for preventing over rotation of an object
A rotational over travel protection device for preventing over rotation of at least one of a cable, or a component operable with the rotational over travel protection device is provided. The device includes a housing, a rotatable shaft connected to the housing that can rotate relative to the house, and a triggering device supported in the housing and rotatable with the rotatable shaft. The device also includes a first and second rotational limit switch disposed in the housing. The switches are operable to be activated by the triggering device to arrest rotation of the rotatable shaft upon relative rotation of the rotatable shaft and the housing either a first or second rotation direction, respectively, at least 180 degrees from a zero position.
Container including illuminator with zipper-actuated switch having magnetic latch
A switch includes magnet for biasing a contact arm into a close position, the contact arm forced into an open position when an actuating force is applied to an extending portion of the arm. The switch can be operatively coupled to a zipper system of a container such that a zipper slider, when moved to a closed position of the zipper system, contact the extending portion of the arm to provide the actuating force. A circuit is formed by electrically connecting the switch to a battery and light source. The light source illuminates the interior of the container when the zipper slider is moved from a closed zipper system position.
OPERATION STOPPING SWITCH FOR AN ELECTRONIC DEVICE
An electronic device is provided that includes an electronic component within the electronic device, a kill switch; an access door providing access to the electronic component and the kill switch and a latch for securing access to the electronic component in a closed position and for giving access to the electronic component in an open position. The latch activates the kill switch in the open position, independently of a position of the access door.
CENTRIFUGAL SWITCH FOR A MOTOR OF A CLOTHES DRYER
A centrifugal switch for a motor of a clothes dryer is provided. The end of a bracket and the end of a fixed contact piece are arranged in alignment and each has a raised contact. An upper limit piece slot is provided above the contact of the bracket inside the housing. The aligned ends of the bracket and the fixed contact piece are located above the aligned ends of a starting spring piece, a starting lower piece and a starting upper piece. A pressing head at one end of the rocking lever is located above one side of the fixed contact piece aligned with the bracket. The other end of the rocking lever extends outside the housing. When the centrifuge is not rotating, a movable sleeve of the centrifuge slides into the rocking lever to trigger the centrifugal switch.
Safety switch
A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).
Rotational Over Travel Protection for Preventing Over Rotation of an Object
A rotational over travel protection device for preventing over rotation of at least one of a cable, or a component operable with the rotational over travel protection device is provided. The device includes a housing, a rotatable shaft connected to the housing that can rotate relative to the house, and a triggering device supported in the housing and rotatable with the rotatable shaft. The device also includes a first and second rotational limit switch disposed in the housing. The switches are operable to be activated by the triggering device to arrest rotation of the rotatable shaft upon relative rotation of the rotatable shaft and the housing either a first or second rotation direction, respectively, at least 180 degrees from a zero position.
Paddle switch system
A paddle switch system comprises a housing, a paddle having a pivot member pivotally disposed in the housing for operating an electrical switch within the housing in response to a force on the paddle, a cover coupled to the housing wherein the housing and the cover partially enclose the paddle, and a vibration reduction mechanism disposed in the housing proximate the pivot member of the paddle. The electrical switch comprises a dome switch and the paddle is disposed in the housing to partially preload the dome switch.
