Honeywell MICRO SWITCH SM Series Basic Switches
Honeywell MICRO SWITCH SM Series Basic Switches are subminiature snap-action switches designed for repeatability and long operating life. These switches combine small size with electrical capacity, precision operation, and reliable performance across a wide temperature range. The SM series basic switches feature current ratings from 0.1A to 11A and a maximum voltage rating of 250Vac/30Vdc. These devices have an operating temperature range from -54°C to +204°C and a life of up to 10,000,000 cycles. Applications include aircraft cockpit controls, aircraft door monitoring, fuel level sensing in power generation, and industrial pressure and temperature switches.
