• A push button operator, contact block, lens, and filament lamp or LED are required to create a full set of illuminated push button switches.　For compatible contact block coupling connectors, the representative part number; See 680-2158 680-2158.　For conforming lenses, the representative part number; 745-2499 745-2499,; 745-2530 745-2530,; See 745-2512 745-2512.　For suitable filament lamps, the representative part number; See 655-9211 655-9211.　For appropriate white single-chip LEDs, the representative part number; See 225-997 225-997.
• RS IP65 Indicators and Push Button Switches - ADA16S Series (16 mm) - Partially assembled, modular, illuminated/non-illuminated, momentary/alternate, round/square/rectangular push button switches and compatible pilot light indicators that conform to the industry standard 16 mm diameter cutout holes for 0.5~5 mm thick panels.　You can choose between a convex bezel profile type that prevents accidental touch, a push-button switch, or an embedded mounting type that allows you to mount the pilot light indicator approximately flush with any panel.　Each push button switch or pilot light indicator is quick and easy to assemble and provides a fully assembled IP65 rated waterproof panel sealing.
• The push-button operator can be attached to any contact block, allowing for a variety of switch functions and lighting combinations (For contact blocks and lamp blocks, part number; 745-2427 745-2427,; 745-2423 745-2423,; See 745-2420 745-2420).　Each contact block has a 2.8 x 0.5 mm universal terminal for direct soldering or plug-in receptacles.　The pilot light indicator has a lamp block installed. For illumination, use a T1 (MG5.7 s) small threaded filament lamp or LED and select a suitable lens.　Lenses compatible with the ADA16S Series push button switch and pilot light indicator are available in a variety of colors (Blue, green, orange, red, white, black) and shapes (Round, Square, Rectangular).　Each lens has a flat profile and is made of carvable polycarbonate.　Two types of bezel converters (Square type is part number.; 745-2552 745-2552, rectangular; 745-2559 745-2559) convert square and rectangular push-button switches (; 745-2458 745-2458,; 745-2461 745-2461,; 745-2451 745-2451,; 745-2470 745-2470) and pilot light indicators (; 745-2489 745-2489 and; 745-2483 745-2483) to embedded countersunk head types.　Each converter comes with a fixed bow, gasket, and black plastic embedded bezel.　Other ADA16 Series switches include key switches, rotary selector switches, buzzers, and emergency stops. For each of these switches, the part number; 745-2433 745-2433,; 745-2439 745-2439,; 745-2436 745-2436,; 745-2445 745-2445,; See 745-2442 745-2442.
• Waterproofing Grade: IP65 Panel Cutout Diameter: 16 mmO Round, Square, and Rectangular Operator Illuminated or Non-Illuminated VDE with Momentary and Alternate Switch Features Rated 5 A 250 Vac (8 A 125 Vac) Silver Contact Insulation Resistance: >50 MΩ Flame Retardant Grade: UL94-V0 Operating Temperature Range: -25 → +55 °C (-25 → +70 °C without lamp)
