APEM Introduces Low Profile, Surface Mount, Dip Coded Rotary Switches


Haverhill, MA - APEM Components, Inc., a leading manufacturer of high quality miniature and industrial switches, introduces its P36 Series, RoHS compliant, DIP Coded Rotary switches. The P36 Series comes in a compact, 7.4mm square package, designed to save PCB space. Typical applications include security systems, laboratory instrumentation, telecommunications equipment and computer peripherals.

APEM’s P36 Series DIP Coded Rotaries are available in SMT and through-hole configurations and are process sealed to ensure reliable operation. These dynamic switches are available in 10 and 16 positions in four output code configurations: BCD, BCD complement, hexadecimal and hexadecimal complement.

DIP Rotary Switches feature three actuator styles: screw driver, spindle and slotted spindle.
