Publication number: 20220084764Abstract: A security switch for detecting an actuator comprises a magnetic field source, a magnetically susceptible object, and a circuit. The magnetic field source is configured to produce a magnetic field gradient. The magnetically susceptible object is suspended at a first position at least in part due to the magnetic field gradient and shiftable to a second position when the actuator affects the magnetic field gradient. The circuit is configured to detect when the object is in the second position.Type: ApplicationFiled: September 15, 2021Publication date: March 17, 2022Inventors: Joseph C. Hedeen, Ronald Sayles, Randall Woods

Patent number: 11069496Abstract: An improved magnetic switch assembly (16) has a housing (24), a first electrode (40) positioned within the housing (24), a second electrode (42), and a magnetically movable component (48) located within the housing (24) and shiftable between a first position in simultaneous contact with electrodes (40, 42), and a second position out of such simultaneous contact. The electrode (40) has a radially enlarged contact section (44, 58) adjacent the free end thereof which prevents hangup or sticking of component (48) in the first position.Type: GrantFiled: February 23, 2018Date of Patent: July 20, 2021Assignee: Magnasphere CorporationInventors: Joseph C. Hedeen, Randall Woods, Larry Hedeen

Patent number: 10541095Abstract: Switch apparatus (54), designed to detect relative movement between first and second members (60, 62), includes a switch assembly (48) comprising a switch unit (20), a biasing element (50), and an operating member (52). The unit (20) has a conductive housing (22) with first, second, and third electrical pin contacts (36-40) and a shiftable body (46). The body (46) is magnetically correlated with both the element (50) and operating member (52). When the members (60, 62) are close, the operating member (52) maintains the shiftable body (46) in one switch position, whereas when the members (60, 62) are separated, the biasing element (50) magnetically moves body (46) to another switch position, thereby detecting the relative movement).Type: GrantFiled: May 21, 2018Date of Patent: January 21, 2020Assignee: Magnasphere CorporationInventors: Christopher Woods, Randall Woods, Joseph C. Hedeen

Publication number: 20180182581Abstract: An improved magnetic switch assembly (16) has a housing (24), a first electrode (40) positioned within the housing (24), a second electrode (42), and a magnetically movable component (48) located within the housing (24) and shiftable between a first position in simultaneous contact with electrodes (40, 42), and a second position out of such simultaneous contact. The electrode (40) has a radially enlarged contact section (44, 58) adjacent the free end thereof which prevents hangup or sticking of component (48) in the first position.Type: ApplicationFiled: February 23, 2018Publication date: June 28, 2018Applicant: Magnasphere CorporationInventors: Joseph C. Hedeen, Randall Woods, Larry Hedeen

Patent number: 9685290Abstract: Small, low-profile magnetic switch assemblies (26, 76, 126, 168) include a base (38, 78, 156) equipped with first and second laterally spaced apart switch electrodes, indentations (62, 102, 158) between the electrodes, and electrically conductive movable components (72, 110, 166), which are magnetically shiftable between a first switch position in simultaneous contact with the base electrodes, and a second switch position out of such simultaneous contact. The switch position of the component (72, 110, 166) is determined by the magnetic field conditions experienced by the component (72, 110, 166). The indentations (62, 102, 158) and associated shiftable components (72, 110, 166) permit the assemblies (26, 76, 126, 168) to be constructed as comparatively tiny units, which may be mounted on circuit boards.Type: GrantFiled: March 18, 2016Date of Patent: June 20, 2017Assignee: Magnasphere CorporationInventor: Joseph C.
