Hermetic Switch Reed Switches and Accessories See Us at www.hermeticswitch.com c ISO 9001 Certified Reed Switches 5 Highest quality reed switches feature contacts hermetically sealed in a protective atmosphere. Protected contacts mean reliable operation in wet, oily, dirty N even explosive N environments. Glass capsule size ranges from a compact 2-inch glass length down to under 1/ 4-inch long! Ideal for use in proximity switches, flow meters, counting devices, limit switches, reed relays and precision instrumentation. Actuate Time: 3 millisecond or less on 2-inch capsules; 1 millisecond or less on capsules under 1-inch in length. Typical Life Expectancy: 50 million operations. Contacts: Form A (SPST-N.O.) or Form C (SPDT), may be actuated by permanent magnet or coil. Magnets and coils sold below. Average Shipping Weight: 1 ounce each. Microminiature Reed Switches C Max.
