Rotaries

Product catalog summary
Specifications:
The document outlines the specifications for the MRB and ND series of miniature PCB process sealed rotary switches. Key features include molded terminals for contamination prevention, a positive detent mechanism for tactile feedback, break-before-make contact timing, and a sliding contact mechanism. The switches are durable due to their metal bushing and frame, and an optional exterior o-ring provides panel sealing to IP67 standards. Terminal spacing aligns with standard PC board grid spacing.
Procedures:
The document details the ordering process, specifying poles, circuits, indexing, terminals, and knob colors. It includes typical switch dimensions and panel cutouts, highlighting the importance of cap clearance for right-angle models.
Standards & Certifications:
The switches meet UL94V-0 flammability standards but lack UL recognition or CSA certification. They are suitable for low-voltage, low-current, logic-level circuits.
Environmental Data:
Operating temperature ranges from -25°C to +75°C, with humidity resistance of 90-95% for 96 hours at 40°C. The switches are tested for vibration and shock resistance.
Materials & Finishes:
Construction materials include glass fiber reinforced polyamide for the actuator and housing, nitrile butadiene rubber for the o-ring, and beryllium copper with gold plating for the movable contact.
Processing:
Soldering recommendations cover wave and manual soldering, with specific switch positions during soldering. Automated cleaning is supported.
Distinctive Characteristics:
The sealed construction prevents contamination and supports automated soldering and cleaning. The design features highly visible legends and options for screwdriver or shaft actuation for reliable code setting.
Overview:
The document also provides technical specifications and assembly instructions for the HS, TS, and PS models of rotary switches, detailing dimensions, stopper settings, and hardware components.
Stopper Settings:
Instructions include turning the shaft counterclockwise to the extreme left before setting the stopper, loosening the nut to raise the stopper plate, inserting the stopper in the desired hole, and tightening the nut firmly.
Hardware Components:
Standard hardware includes AT526 Hex Mounting Nut, AT518 Locking Ring, and AT520 Split Lockwasher. Optional mounting supports are available for PS models, but screws are not provided.
Knob Orientation:
Knobs for D-flat shafts can be oriented to suit specific panel needs by sliding over the square adaptor. Two types of knobs are available: AT431 Large Knob and AT432 Small Knob, both made of phenolic resin with a white indicator line.
Additional Notes:
Switches are viewed from the shaft end and shown in position 1. Terminal numbers are located on the switch bottom, and stopper positions are molded on the top.
