Shaft is sealed by o-ring inside the bushing; panel is sealed by o-ring at the base of the bushing. Seals do not alter dimensions as shown in the drawing when switch is mounted. Panel seal is silicone rubber. Shaft seal is an o-ring per MIL-P-5516B. Shaft and panel seal is not available on adjustable stop switch. Rated: To make and break 125 mA at 30 Vdc resistive at standard conditions Life Expectancy: 25,000 cycles at rated load; 50,000 cycles mechanical. For ratings at different loads and conditions, contact Grayhill. Contact Resistance: 100 milliohms maximum (50 milliohms initially) Insulation Resistance: As measured between mutually insulated parts Initially: 50,000 megohms minimum After Life: 10,000 megohms minimum Voltage Breakdown: 500 Vac between mutually insulated parts Carry Current: These switches will carry 3 amperes with a maximum contact temperature rise of 20C. Adjustable stop switch lets you limit the number of positions. Remove and relocate pins in the front plate. A sticker holds the pins in place. With the exception of holes in the front plate, all dimensions, ratings, and characteristics are the same as the other Series 71 coded switches. For diagrams, see Standard Switch. Ordering Information Specifications Electrical Rating Adjustable Stop Switches Additional Characteristics Rotational Torque: 8 to 16 oz-in. Contacts: Non-shorting wiping contacts Shaft Flat Orientation: As shown in the drawing, switch would provide a decimal 1 output. Materials and Finishes Base: Diallyl per MIL-M-14 Rotor Mounting Plate: Thermoplastic. Rotor Contact: Phosphor Bronze, gold-plated 30 microinches minimum Terminals: Brass, gold plate (20 microinches min) over silver plate (300 microinches min) Additional Materials: Other switch materials and finishes are the same as listed for the standard switch.
