MICRO SWITCH™ Premium Large Basic Switches BZ | BA | BM | BE | 6AS Series Datasheet

MICRO SWITCH™ Large Premium Basic Switches Accurate, reliable, and repeatable, MICRO SWITCH™ BZ/BA/BM/BE Series features precise operating characteristics and enhanced life. These premium, large snap-action switches offer precision operation and sensitive differential travel. Utilizing state-of-the-art manufacturing processes and quality controls, Honeywell has engineered premium, large snap-action switches that meet various international agency requirements. Some models have military qualifications. MICRO SWITCH™ BZ/BA/BM/BE Series are often used for precision on/off applications, as well as end of limit, presence/absence, and manual operator interface functions. Their engineered design is suitable for various application needs. Configured options with BZ, BA, BM, and BE switches provide a wide variety of operating and interface characteristics. The MICRO SWITCH™ 6AS Series consists of two large premium BZ/BA/BM/BE snap-action switches ganged together and actuated by a single actuator. Field adjustable operating point is an option for one or both switches. What makes our switches better? • Industry-leading temperature range for options up to 204 °C [400 °F] and temperatures as low as -55 °C [-67 °F] • Exclusive current carrying capability of up to 25 A • International approvals: UL, CSA, ENEC, CE listings • Options for circuitry, styles, connection types and a wide selection of actuator styles • Dependable performance - tested up to 20 million mechanical cycles • MICRO SWITCH™ legacy and expertise - over 75 years of engineering excellence and experience Operating in extreme temperatures is all in a day’s work for MICRO SWITCH™ large basics!

Features GLOBAL USE AND APPROVALS and Benefits Switches certified to UL, CSA, ENEC, and CE for global use FLEXIBILITY OF PRODUCT CHARACTERISTICS Honeywell’s large basic switches offer various operating force and differential travel options to meet the actuator type. Designed with momentary or maintained contact action, these switches may perform a variety of functions as well as offering a choice of actuation, termination and operating characteristics for design flexibility Listings certified for global use and mulitple applications VARIENTS FOR EXTREME CONDITIONS With an IP64 sealing option to maintain switch enclosure sealing, many listings can be used in dirty, harsh environments with their dustproof and splash resistant seals. Many versions operate in extreme temperatures, up to 121 °C [250 °F], and several with high temperature options for up to 204 °C [400 °F], as well as temperatures as low as -55 °C [-67 °F] EASY INSTALLATION REDUCES OVERALL COSTS The switch’s enlongated mounting hole allows for easier, more accurate mounting TIGHT HYSTERESIS/DIFFERENTIAL TRAVEL Designed with a hysteresis as small as 0,008 mm [0.0003 in], the BZ/BA/BM/ BE switches may be used in applications where very tight and sensitive control is required between the operate and release points Standardize switching packages CURRENT CAPACITY FROM LESS THAN 1 A TO 25 A With a broad current capacity, one switch package can control a wide range of electrical loads. As requirements vary for applications, a standardized switch package may help reduce costs and increase application flexibility. Gold contacts available for controlling low energy/low power circuits ENHANCED PERFORMANCE Internal flat spring design delivers optimum performance and switch reliability MILITARY APPROVALS MIL-PRF-8805 switches available for military-specified applications sensing.honeywell.com 3

Potential Applications BUILDING CONTROLS AND EQUIPMENT Often used in a building’s boiler/heater controls, in HVAC systems to sense exhaust pressure on high efficiency furnances, and in fire suppression systems to sound alarm when sprinkler activation/waterflow is detected. May also be used in machine tools to limit the maxiumum movement for pieces of equipment DOORS AND LIFTS May be used in elevators and lifts to sense if the car is in position before the door opens and on door-latching mechanisms to indicate door closed and/or door locked SEMI-TRUCKS AND TRAILERS Can be used to disengage the cruise control when the clutch pedal is depressed and for diesel engine brake assist. For surface transportation equipment, can be used as a seat switch VALVES Detects whether a valve is “open” or “closed” TIMING DEVICES Often used in commercial/industrial-grade timers to turn outputs “on” and/or “off” at preset times COMMUNICATION SYSTEMS May be used as a door interlock on communication consoles or enclosures FOOT SWITCHES In commerical and industrial foot switch enclosures, may be used as the switching element COMMERCIAL AND INDUSTRIAL KITCHEN EQUIPMENT May be used to indicate door closed and/or door locked for the self-cleaning feature IRRIGATION EQUIPMENT Often used for limiting maximum offset of irrigation towers MEDICAL INSTRUMENTATION In medical and dental equipment, often used in foot switches to control the dental drill and the positioning of the chair 4 sensing.honeywell.com

BZ | BA | BM | BE | 6AS Series 6AS SERIES - PREMIUM LARGE SNAP-ACTION TANDEM SWITCH ASSEMBLY The MICRO SWITCH™ 6AS Series consists of two large premium BZ/BA/BM/BE snap-action switches ganged together and actuated by a single actuator. Operating characteristics are dependent upon the type of individual switches and actuators chosen. Field adjustable operat- ing point on one or both basic switches. Solder, A2, and T-type terminations available, along with straight, roller, and leaf levers. Mounting holes accept pins or screws of 3,53 mm [0.139 in] diameter. Often used for boiler controls or anywhere two circuits need to be controlled by one actuator.

BZ | BA | BM | BE | 6AS Series OPERATING CHARACTERISTICS Table 3. Operating Characteristics Definitions Characteristic Description Differential Travel-DT Plunger or actuator travel from point where contacts “snap-over” to point where they “snap-back.” Free Position-FP Position of switch plunger or actuator when no external force is applied. Full Overtravel Force Force required to attain full overtravel of actuator. Position of switch plunger or actuator at which point contacts snap from normal to operated position. With Operating Position-OP flexible or adjustable actuators, the operating position is measured from the end of the lever or its maximum length. Location of operating position measurement shown on mounting dimension drawings. Amount of force applied to switch plunger or actuator to cause the contact “snap-over.” Note in the case of Operating Force-OF adjustable actuators, the force is measured from the maximum length position of the lever. Overtravel-OT Plunger or actuator travel safely available beyond operating position. Pretravel-PT Distance or angle traveled in moving plunger or actuator from free position to operating position. Amount of force still applied to switch plunger or actuator at the moment contacts snap from operated position Release Force-RF to non-operated position. Total Travel Distance from actuator free position to overtravel limit position. 18 sensing.honeywell.com
