1250 Series Subminiature Shaftless Precision Rotary Switches

A subminiature precision rotary selector switch, the SERIES 1250 is 0.350 inches in diameter and rated at 30,000 operational cycles. It has been engineered to meet all applicable requirements of MIL-S-3786.

The basic series 1250 is available as a 1 pole, 1-8 position or a 2 pole, 2-4 position switch. It is a non-shorting switch with 45 and 60 degree indexing. It has PC terminals and shaft seal for contaminant-free operation.

The series 1250 is ideal for avionics, communications, test equipment and command and control applications where space is limited and strict environmental reliability requirements are needed.

Superior construction, using materials that meet the strictest standards, ensure these subminiature switches provide excellent current switching capacity and constant low contact resistance. Rigorous inspection, testing requirements, and procedures ensure long life and high reliability.

The Cole series 1250 switch provides the ultimate mechanical and electrical reliability with its unique design.
