Thumb Rotary Switch - A7D/A7DP
Caution
Product Description
An ultra small, cost-effective push-in type thumb rotary switch.
[Features]
· The integral molding reduces the number of parts used in its construction. Despite its low cost, it boasts improved reliability.
· Uses long-lasting resin springs to achieve a long mechanical durability expectancy of 30,000 operations.
· The series includes pen-push types which help prevent operational errors.
· Available in black or light gray.
[Applications]
· Convert and output numerical values as binary, decimal and hexadecimal code by combining ON/OFF signals from multiple contact circuits.
