YF011U2C203NQ Description

Short technical summary and product information.

The C&K Components YF011U2C203NQ is a miniature 4-tumbler keylock switch from the YF series, designed for applications like cash registers, point-of-sale terminals, and server hardware. This switch features a Single Pole Double Throw (SPDT) circuit with two positions and 90° indexing.

 

Electrically, it is rated for 4A at 125V AC or 28V DC, and 2A at 250V AC. The contact resistance is typically below 10 mΩ, with an electrical life of 10,000 make-and-break cycles at full load. Insulation resistance is a minimum of 1 GΩ, and dielectric strength is 1,000 Vrms minimum.

 

Mechanically, the switch has a panel mount type with a circular cutout dimension of 11.99mm diameter. It features solder lug terminations and a flat key actuator. The switch housing is constructed from 6/6 Nylon (UL 94 V-2), and the lock is made of zinc alloy with a stainless steel facing. Keys are nickel-plated brass.

 

This model is specified with silver-plated copper contacts and epoxy sealed terminals. The YF series is known for its multi-pole and multi-position options, positive detent, and low power capability.
