Description

Harmony 22 mm modular push buttons, selector switches, pilot lights are designed for industry. This range combines simplicity of setup, flexibility and a robust construction. An ingenious locking system consisting of a snap fit head and body that can be tightened with a single screw but still ensuring an easy and yet secure mounting. Harmony XB4/ZB4 are 22 mm chromium plated metal modular push buttons, selector switches and pilot lights connecting to fully metal mounting collar. The operators can be purchased as complete operators or various modules that can be assembled to meet the user’s specific requirement. Harmony XB5/ZB5 are 22 mm plastic modular push buttons, selector switches, pilot lights. The operator can have a round and square plastic bezel. The contacts can be used for low load electrical contact and high power applications. Shake proof connection screws make periodic retightening unnecessary. A complete set of accessories to provide a solution for applications where exposure to high pressure cleaning, dust and extreme temperatures is an everyday occurrence. These harmony 22mm push buttons are used by machine manufacturers (automotive, textiles, timber) and control system panel builders. Certified and approved for meeting requirements throughout all continents: EN/IEC, UL, NEMA, CSA, CCC, Gost, JIS and many more. They have UL and CE markings and have ratings up to IP66 and IP69K.

Features

Custom-engineered to serve as a reliable Emergency Machine Stop (EMS) or Emergency Off (EMO), this device provides a vital safety interface for plant floor machinery. When pressed, the unit utilizes an instantaneous, positive trigger-action and mechanical latching mechanism that locks the push-button into a depressed position, immediately cutting command power to prevent accidental machinery restarts until the safety hazard is completely cleared.
Featuring a prominent, high-visibility 40mm red mushroom head that is completely unmarked for universal industrial compliance, the device is easy for operators to hit in high-stress situations. Once the machinery has been safely serviced, resetting the device requires an intentional, physical pull-to-release pull action, popping the actuator smoothly back out to its standard position.
Belonging to the premium Harmony XB4 product family, this complete assembly features a rugged, heavy-duty chromium-plated metal bezel. It is optimized for installation into any standard 22.5 mm cutout, including the non-illuminated red operator, metal fixing collar, and the pre-installed contact block stack, eliminating the need to spec out individual sub-components or adapter rings.
The switch is equipped with a versatile 1 NO (Normally Open) + 1 NC (Normally Closed) contact arrangement featuring slow-break silver alloy contacts. Carrying an operational current rating of up to 6 A at 120 V AC (or 3 A at 240 V AC) conforming to standard A600/AC-15 utilization categories, the NC contact directly drops out safety contactors or master control relays while the NO contact concurrently flags a PLC input or indicator beacon.
Engineered for demanding industrial environments, this metal-bezel device provides exceptional mechanical resistance to shocks, vibration, and heavy wear. It carries robust IP66, IP67, IP69, and IP69K environmental protection alongside NEMA 4X, and 13 ratings,
