KT11B1SM Description

Short technical summary and product information.

The C&K Components KT11B1SM is a tactile switch designed for surface mount applications. It features a sealed construction providing IP57 ingress protection against dust and water.

 

This switch operates with a SPST-NO (Single Pole Single Throw Normally Open) circuit and has a contact rating of 1VA at 50V AC or DC. The mechanical and electrical life is rated for 100,000 make-and-break cycles at full load. Its operating temperature range is from -40°C to 90°C.

 

The KT11B1SM utilizes gull wing termination for secure surface mounting. The actuator orientation is top actuated, and it has a vertical actuator height off the PCB of 3.64mm. The switch outline measures 6.38mm x 6.22mm. It is non-illuminated.

 

Typical applications for this type of switch include telecommunications, computer products, and instrumentation where a sealed, reliable tactile switch is required.
