  • Dual cross edge contacts for low energy switches
    Patent number: 6166341
    Abstract: A low energy switch contact design uses a flat spring moveable contact with contact portions made from the sides of the spring bent ninety degrees from the main spring body so as to make point contact with a stationary contact edge located either above or below the moveable contact. The spring is preferably bifurcated for redundancy of contact.

  • Low current high temperature switch contacts
    Patent number: 6156982
    Abstract: A low ampere mechanical switch has a contact design creating a line of contact between the moveable and stationary contacts. The stationary contacts are stainless steel and the moveable contact is Inconel.TM.. Both contacts have a thin plating of gold alloy to provide for good mechanical strength at high temperature with a natural lubricating ability. The contact physical design provides good wiping action and mechanical contact while preventing troughing.
