  • Multiple-contact switches
    Patent number: 8847439
    Abstract: Multiple-contact switches are disclosed. An example multiple-contact switch disclosed herein includes a double throw switch having a common terminal, a first throw terminal, and a second throw terminal, the common terminal being coupled to a reference; a first throw circuit coupled to the first throw terminal, the first throw circuit to output an open signal to a process control device when the common terminal is substantially in contact with one of the first throw terminal or the second throw terminal; and a second throw circuit coupled to the second throw terminal, the second throw circuit to cause the first throw circuit to output a close signal to the process control device when the common terminal is substantially in contact with the other one of the first throw terminal or the second throw contact terminal, wherein at least one of the open signal or the close signal corresponds to the reference.
