C&K – Robust switches offer long life in harsh operating conditions


C&K supplies a broad range of high- quality, durable switches for integration into various types of control gear in transportation equipment and off-road vehicles. The switches are ideal for use in control grips, joysticks, off-road panels, hydraulics, power-control panels, heavy equipment, lifts and other applications.

Many of the C&K switches are suitable for harsh applications which are subject to outdoor exposure and heavy use. These products, which are reliable, rugged and sealed against corrosion, include two families of sub-miniature snap-action switches.

The LCS series switches are fabricated in a thermoplastic polyester or high-temperature thermoplastic housing, and feature a copper alloy spring, pivot and terminal. The contacts are either gold-plated or silver alloy. The switches are available in a range of temperature ratings up to a maximum operating temperature of 120°C.

The ZMS series of IP65-sealed snap- acting switches offer a long electrical life of 100,000 cycles when switching 3A at 12V DC. Mechanical life is 500,000 cycles. The switches’ operating-temperature range is -40°C to 85°C.
