摘要： Electrical switch contact sets are disclosed. A disclosed example apparatus includes a movable platform having first and second contacts, where the first and second contacts electrically coupled via the movable platform, and a stationary portion having third and fourth contacts, where the movable platform is movable to bring the first and second contacts in contact with the third and fourth contacts, respectively, to simultaneously close a current path of an electrical circuit associated with the first, second, third and fourth contacts.

摘要： Proximity switches include a hermetically sealed unit that can be used in harsh environments and under significant pressures, such as underwater and in nuclear power facilities, without having any parts that would require replacement or periodic maintenance. The proximity switches are preferably switches actuated by physical movement of a contact in response to changing magnetic forces. The switches are preferably disposed in a body tube optionally including a hermetic seal assembly to seal an open end of the body tube and/or a ferrule that prevents electrical wires attached to the switch inside the body tube from being pulled away from the switch. Further, the switches preferably maintain a contact pressure between electrical contacts sufficient to withstand acceleration seismic testing of 10 g with no contact discontinuity.

摘要： A switch assembly for adapting a non-contact switch into a contact triggered switch, such that the internal electrical state of the non-contact switch can be triggered by mechanical contact with an object or surface. The switch assembly can include an adapter body coupled to the non-contact switch and an actuation body coupled to the adapter body. The actuation body can be movable relative to the adapter body to selectively position a target supported by the actuation body within a sensing region of the non-contact switch. The actuation body can be moved by an external object making contact with a portion of the actuation body.

摘要： A valve signature diagnosis and leak testing device includes a spool valve operatively connected to a pilot valve, the pilot valve being configured to position the spool valve to one of an open position and a closed position. A blocker valve is fluidly connected to a control fluid outlet of the spool valve. An electrical module is operatively connected to the pilot valve, a supply of control fluid, and the blocker valve, the electrical module being capable of sending pulsed electrical signals to the pilot valve and the blocker valve to selectively position the spool valve and the blocker valve to an open or closed position.

摘要： A switch adapter can include a base having one or more openings, a support coupled to the base, and one or more retainers for coupling a switch to the adapter. The support can have one or more openings between its interior and exterior. The retainer can be adapted to couple to at least one of the base, the support, and a combination thereof. The switch adapter can include one or more switches, such as a replacement switch, and can be adapted for replacing a limit switch with a proximity switch. A proximity switch can be coupled to a switch adapter in one or more positions, and a switch adapter can be adapted to couple with a plurality of different switch mounts. A switch adapter can include a mass compensator for adjusting its center of gravity.
