TMCGS40 Limit Switch Replacement

This post is made for informational purposes only. Please review the manufacturer datasheet and specifications before purchasing any replacement parts.

TMCGS40 is actually a marking that can be found on several limit switches manufactured by C&K. I haven’t been able to track down a good breakdown for this code but it seems to be consistent with a DPST circuit, quick-connect terminals, and ratings of 10A at 125/250VAC, 0.25A at 250VDC, 0.5A at 125VDC. I’ve also seen it with a number of different lever styles, so I’ll provide options for each of the ones that I’ve seen.

Actuator Part Number
Roller (short) CKN10057-ND
Roller (long) CKN10058-ND
Lever (simulated roller) CKN1439-ND
Plunger (no lever) CKN1435-ND
