Overview of Keylock and Selector Switches

This document provides detailed information on various types of keylock switches, selector switches, and emergency stop switches, focusing on product series, specifications, and ordering information.

1. Keylock Switches

• Series and Types: Multiple series such as ADA16K6-AR0, ADA16K6-AS0, ADA16K6-AT0, ADA16K6-AA0 with variations in position (two-position, three-position), operation mode (alternate, momentary), and terminal types (soldering/plug-in).
• Flange and Head Shapes: Standard flange, square, and rectangular options are available to suit different panel designs.
• Color and Coding: Color codes (A, C, E, H, I, K, O, S) correspond to different switch variants and functionalities.

2. Selector Switches

• Configurations: Available in 1NO/1NC and 1NO/1NC+1NO/1NC contact arrangements.
• Operation Modes: Alternate and momentary operation modes are offered.
• Series and Protection: Series such as ADD16C4 and ADP16C4 with IP40 protection rating, available in soldering and plug-in terminal types.
• Head Shapes and Flanges: Standard flange, square, and rectangular head shapes to fit various panel requirements.

3. Emergency Stop Switches (Series ADA16E6)

• Design and Operation: Large 28/32 mm pushers designed for easy actuation with thumb or glove, featuring a reset design in the off position.
• Safety Features: High actuation force (2.0 kgf) to prevent accidental stops, with illuminated options (incandescent, LED, neon) for better visibility.
• Contact Arrangements: Options include 1NO/1NC and 1NO/1NC+1NO/1NC, both illuminated and non-illuminated variants.
• Electrical Ratings: Rated for 250V AC 5A (VDE) and 125V AC 8A, compliant with IEC 947-5-1 standards.
• Mechanical and Electrical Life: Mechanical life of at least 100,000 operations (quick-connect terminal) and electrical life of 50,000 operations.
• Protection and Durability: IP65 rating for water, liquid, and oil resistance; insulation resistance of 50 MΩ initially; withstand voltage of 2000V AC at 60Hz for 1 minute.
• Operating Conditions: Temperature range from -25°C to +55°C; storage temperature from -40°C to +70°C.
• Terminal Types: Soldering and plug-in terminals available for flexible PCB integration.
• Approvals: UL, CUL, VDE, and CE pending.

4. Ordering and Model Format

• Model Codes: Detailed coding system for head shape, contact arrangement, lamp type, and lens color.
• Head Shapes: Ø28 mm (illuminated) and Ø24 mm (non-illuminated) with specific unlocking mechanisms (turn lever rotary or turn clockwise).
• Lamp Options: Incandescent lamps with various voltage and current ratings, neon lamps (110V and 220V AC), and LED lamps (6V, 12V, 24V DC).
• Lens Color: Red is the standard lens color for emergency stop switches.

5. Mechanical and Mounting Dimensions

• Mounting panel thickness ranges from 0.5 mm to 5.0 mm.
• Detailed dimensional drawings specify sizes and tolerances for both illuminated and non-illuminated emergency stop switches.

Critical Specifications and Best Practices

• Ensure correct selection of switch type based on operation mode (alternate vs momentary) and position requirements.
• Verify electrical ratings and contact arrangements to match application needs.
• Use IP65 rated switches for environments exposed to water, oil, or liquids.
• Consider illumination options for enhanced visibility and safety.
• Follow mounting dimension guidelines to ensure proper installation and panel compatibility.
• Utilize the special terminal designs for ease of PCB integration, choosing between soldering or plug-in terminals.
