HSIs Series 6100 environmentally sealed switch is designed for applications where high reliability is required in a high or low temperature environment. Combining long life and precise action, this switch is used in a wide variety of commercial and military aircraft and space applications. These switches can perform such functions as indication for door locks, landing gear position, valve position and throttle control. Military applications include brake lights on military vehicles, gear shift indicator for tanks and other applications where a resiliently sealed, high reliability switch is required. Incorporating an elastomer seal, which enables high sensitivity and low operating pressure, the switch has a maximum leak rate of 1 x 10 to the power of -6 atm cc/set. Fine silver contacts are standard and gold alloy or platinum contacts are also available. Electrical and mechanical life are conservatively rated at 100,000 operations. Also available in the 6100 Series is an ultra high temperature, non-sealed switch with a range of -65degreeF to +7OO"F (-54degreeC to +371degreesC).
