MICRO SWITCH™ Hermetic Sealed Basic Switches HM Series Datasheet MICRO SWITCH™ HM Series Hermetic Sealed Basic Switches Honeywell HM hermetic sealed miniature basic switches are designed for a variety of commercial and military aircraft as well as equipment for deep space applications (high altitude requirements). These miniature hermetic sealed switches can be found in a variety of other applications including military land vehicles, marine environments, and other harsh industrial environments. The switches are available as a MIL-PRF-8805 qualified switch. Select HM switches are available with UL 508 certification for industrial or surface transportation applications. The MICRO SWITCH™ HM hermetic sealed switch design incorporates the glass-to-metal and metal-to-metal sealing with more than 50 years of use in multiple applications. The hermetically sealed HM basic switches are ideal where a symbol 5 seal is required for stringent applications including a wide range of temperatures from -184 °C to 260 °C [-300 °F to 500 °F]. Designed with a stainless steel housing and hermetic seal construction, the HM switches are suitable for applications where dust, water, other particulate contaminants, and corrosive gases are present. The HM basic switch provides versatility with bifurcated gold contacts for controlling low energy loads (mA and mV) reliably or silver contacts for switching power duty loads at 30 vdc or 115 Vac, 400 Hz. Electrical connectivity to the switch is achieved with individual wire leads or “through hole” solder posts adding to the versatility of the HM switch. What makes our switches better? Precisely detects position of mechanical components within a particular system that is susceptible to physical and atmo- spheric (corrosive gas, oxygen, etc.) elements Consistent and precise performance in a hermetic-sealed package for adverse, inclement environments Functionality over a large temperature range – can tolerate very low and high temperatures Honeywell can create value-added HM assemblies for unique, custom applications beyond a simple HM switch HM switches are available with MIL-PRF-8805 qualifications or UL 508 certifications HM Series: when you need a switch with out-of-this-world performance!

UL CERTIFIED Select HM catalog listings are UL 508 certified for industrial and surface transportation applications. TINY Miniature package size requires minimal space on equipment. Hermetically sealed with wide temperature range SEALED TIGHT HM Series’ Symbol 5 hermetic-sealed enclosures are suitable for applications at sea level, high altitude, or deep space. LOW VOLTAGE AND POWER DUTY CAPABILITY MICRO SWITCH™ HM products are available with silver contacts for control of power duty circuits or gold contact surfaces for control of logic level circuits. LEVERS FURTHER EXPAND FUNCTIONALITY Auxiliary actuators expand the versatility of the switch for additional applications. WELL SUITED FOR LOW AND HIGH TEMPERATURES For endurance in harsh temperature environments, wide temperature range is available from -184 °C to 260 °C [-300 °F to 500 °F]. Operate point stability is maintained over the specified temperature range. sensing.honeywell.com 3 Potential Applications MILITARY AIRCRAFT AND HELICOPTERS • Detects landing gear bay doors in closed and locked position • Senses engine fuel valve position • Identifies when external hatches and doors are in closed and/or locked position COMMERCIAL AIRCRAFT AND HELICOPTERS • Detects landing gear bay doors in closed and locked position • Senses engine fuel valve position • Identifies when external hatches and doors are in closed and/or locked position • Miscellaneous applications inside commercial aircraft cabin, including waste management valve position, refreshment (liquids and food) stowed and locked position, HVAC, and oxygen valve position AVIATION GROUND SUPPORT EQUIPMENT • Monitor position of valves, doors or panels, for open, closed, or locked position SPACECRAFT • Identifies when external hatches and doors are in closed and/or locked position • Senses engine fuel valve position • Select sensing applications inside spacecraft cabin POWER GENERATION, OIL AND GAS • Internal switch element in pressure switches, temperature switches, and/or flow switches sensing.honeywell.com 4 MICRO SWITCH™ Hermetic Sealed Basic Switches Table 1.
