I. Overview思维导图模板大纲

Cole Instrument specializes in high-reliability rotary switches designed for demanding applications, including aerospace, military, medical, industrial, and critical ordnance. The switches are generally compact, enclosed for environmental protection, and built to meet or exceed MIL-DTL-3786 standards, often tested per MIL-STD-202. A core theme is the extensive customization available, with a wide range of options and configurations to suit various application requirements. Cole also has AS9100 and ISO9001 certifications. The company encourages customers to contact them directly for assistance with creating specific part numbers, emphasizing the complexity and customization.

II. Key Themes & Concepts

• High Reliability and Durability: The switches are consistently designed for "demanding usage" and engineered to meet rigorous military and industry standards\. Testing includes thermal shock, vibration, shock, moisture resistance, explosion proofing, and salt spray \(MIL\-STD\-202\)\. • Subminiature Precision: Many of the switches have compact size while maintaining precision\. For example the 1150 series are "Subminiature Enclosed Precision Rotary Switch" with a diameter of \.320 inches\. • Customization: A major selling point is the vast array of options and configurations, including: • Indexing Angles: 30°, 36°, 45°, 60°, and 90° indexing are commonly available\. • Number of Poles and Positions: Switches are available in 1, 2, 3, 4 and 6 pole configurations and various positions per pole\. • Contact Types: Both shorting \(make\-before\-break\) and non\-shorting \(break\-before\-make\) contacts are available\. • Terminal Types: Solder lug and printed circuit \(PC\) terminals are common\. Turret type terminals are also available in the 2020 series switches\. • Shaft Options: Various shaft diameters, screwdriver slots, panel and shaft seals, push/pull mechanisms, and spring returns are offered\. • Stops: Adjustable and fixed stops are options, as are push\-to\-turn isolation posts\. • Shielding: RFI/EMI shielding is an available option\. • Materials: The use of materials like diallyl phthalate and thermoplastic glass\-filled rotors for durability and resistance to contamination are also common features\. • Key Locks: Keylock variants are available with Medeco cylinders for enhanced security\. • Coded Options: Some switch series are available with coded outputs like Binary Coded Decimal, Hexadecimal, and Octal\. • Illumination: The IS3600 series has an illuminated shaft • Application Focus: The switches are explicitly designed for applications in: • Avionics • Communications • Test equipment • Command and control systems • Aircraft • Medical devices • Industrial controls • Critical ordnance • Electronic equipment • Part Numbering System: While basic part numbers are provided, there is a system to specify configurations and options\. The part numbers specify the series number, indexing angle, number of poles and positions, and a string of alphabetical option designations\. For custom ones , a new unique part number is assigned, not related to the company's coding system but and IPP number\. • Push/Pull and Spring Return: Many switches offer specialized actuation, including push/pull mechanisms and spring return functionality which can be implemented in different ways with pull\-to\-turn or push\-to\-turn actions and can be combined to isolate or make certain positions accessible with more force or with a specific directional approach\.
