The stainless steel MCS18 ES and MCS22 ES switches expand the company's line of high impact metal switches. This series provides long-wear in harsh environments. The switches are resistant to impact and are especially suited for applications exposed to heavy use and abuse. Momentary actuation is smooth with a minimal force of 2.8N and medium travel of 1.7 mm. The switch actuator and housing are constructed of high-grade stainless steel and have a built-in mechanical end-stop to protect the contact element under stress.
