EECO S21SJ Thumbwheel Rotary Switch

EECO’s 1100 Series thumbwheel switches provide a versatile solution for various applications requiring rotary switching functionality. Featuring a compact, snap-in design, these switches offer four different actuator styles, including standard thumbwheel, push-set, pen-set, and lock-set models. The pen-set and lock-set models are particularly well-suited for critical “set and forget” applications where accidental setting changes must be prevented. Available in binary or decimal code versions, the 1100 Series switches are backed by EECO’s one-year warranty and are fully compliant with European Lead-Free and RoHS directives.
