Description
Technical Field
The utility model relates to the technical field of switches, in particular to a radio frequency switch with a flexible printed circuit contact strip.
Background
A radio frequency switch is a special type of electromechanical relay (or switch) in which a Radio Frequency (RF) signal is connected or disconnected between terminals in the switch. Typically, the rf switch uses a push rod to push the movable conductive sheet into contact with a pair of connector terminals and connect an rf signal path between the two connector terminals. One common design is to swing a see-saw type soft magnet under the action of a pair of electromagnets to push the switching action of the push rod. To achieve repeatable and reliable contact between the conductor terminal and the connector terminal, stopper posts are placed on both sides of the conductor terminal to limit lateral movement of the conductor reed. Such a stopper post creates additional friction between the rod and the conductor reed, creating particles that contaminate the contacts, thereby degrading the reliability of the electromechanical relay (or switch).
Accordingly, there is a need to provide a new radio frequency switch with flexible printed wiring contact strips that addresses the above-described problems.
