Patent number: 10734173Abstract: In a switching device (1) for converting a mechanical movement into an electrical switching signal, comprising a housing (2) and an electrical switching element (3) that is connected to the housing (2) and can be moved relative to it, the switching device (1) should, firstly, occupy a significantly reduced space and, secondly, be manufactured exceedingly cost-effectively and can be connected to a circuit board (13) in a simple and straightforward manner without the circuit board (13) restricting or reducing the space available for the switching device (1). This task is accomplished in that the housing (2) and the switching element (3) enclose a space (5), that at least one switching contact (11) is provided in the base (6) of the housing (2) and that the particular switching contact (11) projects in the direction of the switching element (3) and beyond the outer contour of the base.Type: GrantFiled: January 13, 2016Date of Patent: August 4, 2020Assignee: RAFI GmbH & Co. KGInventors: Peter Glück, Albert Wasmeier, Karl Riedter, Manuel da Silva

Patent number: 9339989Abstract: A fabric for interconnecting two opposite outer sheet layers and comprising two foam layers, each facing one of the opposite outer sheet layers, and an adhesive layer between each foam layer and the corresponding outer layer and a lateral foil, a foil being disposed between the two foam layers, such that the fabric is adapted to be torn apart so as to separate the two opposite layers from each other.Type: GrantFiled: November 13, 2013Date of Patent: May 17, 2016Assignee: RAFI GmbH & Co. KGInventor: Michael Voth

Patent number: 8471164Abstract: A capacitive switch (1) comprising a housing frame (2), a thin-walled cover plate (3) held thereon, a printed circuit board (4) with a copper layer (6) that generates a capacitive field (7) applied to a surface (5) of the circuit board (4) that faces the cover plate (3), the copper layer (6) being connected to an inside surface (8) of the cover plate (3), the capacitive switch (1) being adapted to ensure that electrical devices can be operated safely, in that changes in the capacitive field (7) are picked up by the switch (1) in a redundant manner.Type: GrantFiled: March 2, 2011Date of Patent: June 25, 2013Assignee: RAFI GmbH & Co. KGInventor: Eric Bulach

Patent number: 8003909Abstract: An emergency off switching device for disconnecting an electrically operated machine from a circuit including a plurality of operated machines, includes a housing attached to the machine against which an externally accessible actuator cap is held in an axially movable arrangement, a contact switch accommodated in the housing which is closed when the switching device is in the non-actuated condition and by means of which the machine is electrically connected to the circuit, and a driver sleeve supported against the inside of the housing that is connected to the actuator cap with the free end of the driver sleeve opposite to the actuator cap facing the contact switch and disconnecting it from the circuit in the actuated condition, wherein a monitoring signal is generated when the switching device is in the actuated condition, to ascertain which of a plurality of the switching devices has been actuated.Type: GrantFiled: November 13, 2008Date of Patent: August 23, 2011Assignee: RAFI GmbH & Co. KGInventor: Franz Gessler
