Sub-miniature snap-acting switches target detection applications

snap-acting switches
C&K's LCW series of sub-miniature sealed snap-acting switches come with a contact rating up to 0.1A as first release, delivering a highly repeatable action for very high-precision, detection applications, such as temperature, and pressure switching.

With a variety of actuator configurations (pin plunger, short lever, lever, and simulated lever), the snap-acting switches are highly adaptable. Their compact size and range of available terminal configurations delivers more efficient use of the PCB area available.
A major advantage of the snap switch is their ability to detect any vandalism. For example, if someone forcibly damages an energy meter, the snap mechanism will automatically send a signal to detect this attack – a feature of greater use for metering in remote or difficult to reach locations. Snap-acting switches installed in smart energy meters may not be actuated for years, yet should still operate reliably should the meter be vandalized. Certified to UL 61058-1, RoHS compliant and rated to IP67, the switches are suitable for use in harsh environmental conditions with an operating temperature range of -40 to +120ºC.
