C&K 7105TCWCKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105TCWCKE is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component features momentary-off-momentary (Mom-Off-Mom) switching function with IP67 ingress protection and epoxy-sealed terminals for harsh environment applications. The part is classified as obsolete, making identification of active equivalent models essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105TCWCKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Physical dimensions (17.45mm actuator length, 11.91mm panel cutout, 15/32-32 bushing thread)
• Termination style (PC Pin)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The C&K 7105TCWCPE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: the 7105TCWCPE is active production, whereas the 7105TCWCKE is obsolete.
