PICO137AK Equivalent & Substitute Parts

Part Overview

The PICO137AK is a thumbwheel switch manufactured by TE Connectivity ALCOSWITCH Switches, designed for panel mount, snap-in applications. This BCD complement switch provides 0.4VA contact rating at 20VAC/DC with a pushwheel actuator and 0 to 9 read-out capability. The PICO137AK is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance, repair, and component sourcing. Obsolete status indicates the part is no longer in active production, necessitating the use of functionally equivalent alternatives for new installations or replacements.
