Key Switches Provide Tactile Feedback

Designed for through-hole, circuit board mounting, the company's three- and two-step key switches measure 0.5" in diameter and 0.375" in height. They provide a maximum travel capacity of 1.5 mm with tactile feedback, as well as a life expectancy of 200,000 cycles. Electrical specifications include a maximum contact rating of 0.4 VA at 20 Vac/dc and a contact resistance below 50 m½ typical. The switches are also environmentally sealed, making them suitable for applications where the elements are present.
