The 6700 Series environmentally sealed switch is rated for one million cycles. The 6700 was developed for high cycle harsh environment applications. The need for high cycle limit switches has developed as aerospace and industrial systems have evolved from manual control and feedback to computer controlled mechanisms. The 6700 meets the high life cycle requirements of modern computer controlled systems.

Based on the proven design of HSI’s 6100 series switch, the 6700 incorporates material and process changes to achieve reliable 1 million cycle life. Internal blade material thickness, temper and surface treatment have been optimized in the new design. The metal housing and operating pin are permanently bonded to a resilient elastomer seal. This ensures environmental seal integrity of 1 x 10-6 Atm cc/sec. The switch is configured for operation in the milliamp range. Operating temperature is -85° F to +300° F.
