| Form Factor: |
Card format is given in terms of (height x length). The height is expressed in units of 'U'. The 'U' is a unit used for the front panel of cards. Each 'U' is equal to 1.75 inches. The length normally is in mm (millimeters). The most popular heights are:
| ||
| Your choices are... | |||
| 3U | 3U cards, also known as single height boards, are 100 mm x 160 mm with one 96 pin DIN connector (J1 connector) on the rear that plugs into the backplane. The bus width of a cPCI or PXI card with a 3U form factor is 32 bits. | ||
| 6U | 6U cards, also known as double height boards, are 233 mm x 160 mm with a second 96 pin DIN connector (J2 connector). The bus width of a cPCI or PXI card with a 6U form factor is 64 bits. | ||

| Switch Topology: |
There are three main types of functional topologies for switches:
| ||
| Your choices are... | |||
| General Purpose | Simple switches that consist of independent and isolated relays or FET switches. They can connect one input to one output. | ||
| Multiplexers | A multiplexer connects one input to several outputs, or several inputs to one output. | ||
| Matrix | A matrix switch is an arrangement with several inputs and several outputs. Any number of inputs can be connected to any number of outputs. | ||
| Multiplexer / Matrix | Switch arrangement that can be connected as a multiplexer or as a matrix. | ||
| Other | Other unlisted switch topologies. | ||

| Switch Type: | |||
| Your choices are... | |||
| Relay Switch | This switch uses a mechanical relay to rout or switch signals. It is used, among others, to switch or to scan high voltage signals. There are three types: armature, dry-reed, and mercury-wetted switches. The relay type can be: SPST (single-pole, single-throw), SPDT (single-pole, double-throw), or DPDT (double-pole, double-throw). | ||
| Solid State Switch | Solid-state switches use transistors (FETs and others) to route or switch signals. They are used in applications that require high-speed scanning of low-level signals (±10 V). Because they do not have any moving parts, these switches have a very long life. | ||
| RF Switch | RF switches are ideal for routing high-frequency signals. | ||
| Other | Other unlisted switches (e.g., optical switches). | ||

| |||
| Relay Type: | The type of the mechanical relays of the switch. | ||
| Your choices are... | |||
| SPST |
Single-pole, single-throw contact. There are two types of SPST contacts:
| ||
| SPDT | Single-pole, double-throw relay. It is also known as Form C type of contact. | ||
| DPDT | Double-pole, double-throw. | ||
| FETs | The switch is a solid state and the relay is a field-effect transistor (FET). | ||
| Other | Other unlisted relay types. | ||
