THE ULTIMATE IN A 36 DEGREE ROTATION, SINGLE DECK ROTARY SWITCH, A SUBMINIATURE PRECISION ROTARY SELECTOR SWITCH, THE SERIES 1150 IS 0.320 INCHES IN DIAMETER AND RATED AT 25,000 OPERATIONAL CYCLES. IT HAS BEEN ENGINEERED TO MEET ALL APPLICABLE REQUIREMENTS OF MIL-DTL-3786. The basic series 1150 is available as a 1 pole, 2-10 position or a 2 pole, 2-5 position switch. It is a non-shorting switch with 36 degree indexing. It has PC terminals and shaft seals for contaminant free operation. The Series 1150 is well suited for avionics, communications, test equipment and command and control applications where space is at a premium and tough environmental reliability requirements are necessary. Quality construction, including materials that meet the strictest standards, allows these subminiature switches to combine superior current switching capabilities with constant low contact resistance. Exceedingly stringent manufacturing processes, inspection and testing requirements ensure long life and high reliability. The A1150 and B1150 are designed for the addition of a panel seal. These switches are perfect for miniature switch applications where contamination control is a must and harsh environments are expected. They are ideal when long life and precision in extreme conditions are necessary. Subminiature Enclosed Precision Rotary Switch The A1150 uses the same body as the standard 1150 but with a smaller shaft and ferrule to allow a panel seal. The B1150 uses the standard 1150 shaft and ferrule sizes with a larger body diameter to allow a panel seal. SPEC SHEET REVISION: C – 010318
