Dimensions are in inches. 2. Metric equivalents are given for general information only and are based upon 1.00
5、inch = 25.4 mm. 3. Unless otherwise specified, tolerances are .02 (0.5 mm) for two place decimals and .005 (0.13 mm) for three place decimals. 4. Rotor sequence: When the circuit A-E is energized, the RF energy path is from port A to C. When circuit B-E is energized, the RF energy path is from port
6、A to B. 5. Interlock switch operation sequence: When circuit A-E is energized, the circuit C-D must open prior to circuit F-D being closed. When circuit B-E is energized, circuit F-D must open prior to circuit C-D being closed. All normally closed contacts and normally open contacts must open and cl
7、ose respectively within or before the first .03 inch (0.8 mm) of rotor travel and within or after the last .03 inch (0.8 mm) of rotor travel. The rotor shall come to a stop in its end position without visible bounce and shall not operate the interlock switch during such an oscillation. 6. Drive asse
8、mbly operation: The switch shall not require any holding current. The drive assembly shall be automatically deenergized when the rotor is latched. The direction of drive assembly moving the rotor shall be as specified in the pictorial view. Case 1: After circuit A-E is energized, if the actuation vo
9、ltage is removed from it and the rotor is stopped at some point after its first .03 inch (0.8 mm) of travel and before its last .03 inch (0.8 mm) of travel, the rotor shall continue to its new position (open energy path from port A to port C) by reapplying voltage to circuit A-E. However, the rotor
10、shall return to its original position (open energy path from port A to port B) if the reapplied voltage is applied to circuit B-E. Case 2: After circuit B-E is energized, if the actuation voltage is removed from it and the rotor is stopped at some .03 inch (0.8 mm) of travel, the rotor shall continu
11、e to its new position (open energy path from port A to port B) by reapplying voltage to circuit B-E. However, the rotor shall return to its original position (open energy path from port A to port C) if the reapplied voltage is applied to circuit A-E. 7. Helical thread inserts may be used. 8. The sha
12、pe of the can is optional. FIGURE 1. Switch configuration and schematic, PIN M55041/10-001 - Continued.
