Photo	Title	Description	Datasheet	Commercial: Designed for standard operating environments including laboratories and most commercial applications. Ruggedized: Designed for aerospace and defense applications. Suitable for vibration, acceleration, mechanical shock, thermal cycling, humidity, and other harsh environmental conditions.Product Line	SPDT: Single Pole Double Throw. One input is directed to either of two outputs or conversely, either of two inputs is directed to a single output. SPXT: Multi-Position. Switches with 3 or more throws or positions. Transfer: A four port device with two inputs toggled between two outputs. This configuration is normally used when you want to toggle two sources and two loads. Design	Connector	Reflective: Directs all unselected inputs to an open circuit load.The only source that sees a 50 ohm load is the one associated with the selected position. It is less complicated and less expensive than a terminated switch. If the sources can tolerate an open circuit load, this is the configuration to use. Terminated: Directs all unselected inputs to a 50 ohm load located within the switch body.This is used in systems where the RF sources cannot tolerate an open circuit load condition. When a position is selected the internal 50 ohm load is disconnected from the source and the load becomes the 50 ohm load associated with the instrument connected to the switch Common port. In this type of switch a 50 ohm load is always seen by the RF sources. Type	Maximum rated operating frequency. Functional performance is tested from DC to this maximum frequency. Max Frequency	This is a Normally Closed contact that does not require actuator power to remain closed. It is only closed when no other switch position is selected. When an alternate position is selected by applying current to the appropriate actuator, the Failsafe contact opens and does not close again until current is removed from the selected position. This feature directs signals to a specified path should a failure occur and the system loses power. Another application is one where the user wants one position selected most frequently than other positions. In this scenario the Failsafe position would be assigned to the frequently used position. This is beneficial because the most frequently used state requires no actuator power. Fail-Safe	The switch maintains the selected position magnetically without current draw. Current is required to change positions. Current is required only during the switching phase and an internal current cut-off circuit is used to produce a pulse. The main use of latching switches is in systems that do not have the power available to supply constant actuator current. The magnetic latching feature enables these switches to withstand high shock and vibration environments. Latching switches generate less heat than non-latching switches because of the internal current cut-off design and customer provided cut-off in pulse latching switches. Latching	The switch maintains the selected position magnetically without current draw. A user-supplied DC pulse between 20-50 mSecs is required to actuate a position. The user provides current cut-off. The main use of latching switches is in systems that do not have the power available to supply constant actuator current. The magnetic latching feature enables these switches to withstand high shock and vibration environments. Latching switches generate less heat than non-latching switches because of the internal current cut-off design and customer provided cut-off in pulse latching switches. Pulse Latching	All switch paths are open until a position is selected. Continuous current is required to maintain the selected path. This configuration represents the simplest and most common type of switch. Most users are able to supply the constant current required by these devices and the design is quite rugged and reliable.
