The negative rate disc spring frees Dual-Snap switches from the problems of ordinary constant rate sensing elements such as flat metal diaphragms, bourdon tubes and bellows. The switch does not “trace” fluctuating pressures and therefore the set points STAY set, even under the harshest ambient conditions. The disc spring design makes Dual Snap switches impervious to surges and pump ripples encountered in conventional sensing elements. Contact chatter, premature fatigue and other common switch complaints are eliminated.

All Dual-Snap aerospace switches are designed or can be modified to meet various requirements of MIL-DTL-9395, MIL-STD-810, MIL-STD-202 or RTCA/DO-160. These requirements, among others, include Environmental test requirements such as salt spray, temperature cycling, humidity, sand and dust, moisture resistance; physical characteristic tests such as vibration, shock, and acceleration; electrical characteristic tests such as dielectric, insulation resistance and contact resistance.

60 Years of Innovation

Custom Control Sensors, LLC (CCS) has been a global leader in the design, testing, manufacturing and supply of standard and custom pressure, temperature and flow switches and sensors for the Aerospace, Defense, Industrial and Energy markets since 1958. CCS switches are highly reliable devices that utilize a “DUAL-SNAP” action disc spring principle pioneered by Custom Control Sensors over 50 years ago.
