| Switch Type | |||
| Your choices are... | |||
| Dry Reed Switch | Contains ferromagnetic contact blades sealed in a glass container with an inert gas. | ||
| Mercury Wetted Reed Switch | Mercury is contact material for electrical circuit, mercury to mercury. The contacting faces are renewed by capillary action drawing a film of mercury over the surfaces of the constant switching members as the movable contact member is moved from one position to another. | ||
| Other | Other unlisted, specialized, or proprietary switches | ||

| Pole and Throw Specifications | |||
| Your choices are... | |||
| Single Pole, Single Throw (SPST) | A switch that makes or breaks the connection of a single conductor in a single branch circuit. This switch typically has two terminals. It is commonly referred to as a "Single-Pole" Switch. | ||
| Single Pole, Double Throw (SPDT) | A switch that makes or breaks the connection of a single conductor with either of two other single conductors. This switch typically has 3 terminals, and is commonly used in pairs and called a "Three-Way" switch. | ||
| Double Pole, Single Throw (DPST) | A switch that makes or breaks the connection of two circuit conductors in a single branch circuit. This switch typically has four terminals. | ||
| Double Pole, Double Throw (DPDT) | A switch that makes or breaks the connection of two conductors to two separate circuits. This switch typically has six terminals and is available in both momentary and maintained contact versions. | ||
| Other | Other unlisted, specialized, or proprietary switch poles and throws. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Configuration | |||
| Your choices are... | |||
| Normally Open (NO) | A term used to describe contacts which interrupt the circuit when in their normal position. | ||
| Normally Closed (NC) | A term used to describe contacts which establish a circuit when in their normal position. | ||
