Operation and Driving Al switches are “break before make,” the switched ports are not connected to each other. This prevents damage to sensitive circuits and enhances test simplicity. There are two positions for the N181x family of switches. Standard switching is accomplished by applying the supply voltage to pin 5 (+V) and grounding either pin 4 (A) or pin 3 (B) to actuate the mechanism to the desired state. See page 12, pin-out diagram. Warning minimum switch spacing is 6.0 mm (0.25 inch). The N181x comes with current interrupt, the drive current is automatically disconnected after the switch is fully latched (15 ms). Option 401 drives the switch with TTL/5V CMOS compatible logic, which controls the DC power supply to drive the switch. Option 402 provides electronic indication of switch state. The circuitry consists of two independent commons, which can be connected to outputs corresponding to either position A or B. Because the commons are electrically isolated from each other as well as the drive circuit, this option allows two position signals to be obtained. 3 Document Outline High Performance Electromechanical Switches for Microwave and RF Manufacturing Test Systems Reduce Downtime Raise your Standards Increase Flexibility and Productivity Technology Operation and Driving Specifications Specifications Equations Supplemental Specifications and Characteristics Typical Performance Environmental Specifications Mechanical Dimensions Ordering Information Related Literatures More RF & Microwave Test Accessories
