Honeywell/Microswitch - 11SM1 Switch, Sum-Miniature, SM Series Pushbutton.

The 11SM1 is a single-pole double-throw (SPDT) Subminiature Basic Switch with a plunger actuator and solder terminals. It has silver contacts and it is used for simple or precision ON/OFF application needs. The MICRO SWITCH™ SM series switch is slightly larger than the MICRO SWITCH™ SX series switch. This switch combines small size and light weight with ample electrical capacity, precision operation and long life. The SM Series offers gold contacts for low-energy switching and gold bifurcated contacts for maximum reliability. Bifurcated contacts provide parallel redundancy within the SM switch.

Contacts: SPDT Snap Action, Pin Plunger Limit Switch.

Contact Ratings: 5Amp 250VAC. 30 VDC

Connection: 3 Turret Posts.

Operating Force 5 Oz

Mech: PCB. Body: 19.8mm long x 6.5mm wide x 9.0mm high.
