1. GPTCRM01 Substitution Conclusion Direct substitution is not recommended. The key discrepancies are as follows: the current rating is reduced from 20A AC to 15A AC, posing a risk of overload and compromised reliability when operating near the original 20A design load; the actuation force is significantly higher (increasing from 42–71gf to 158gf), which alters the tactile feel and operational characteristics of the switch and may prevent effective actuation by the original drive mechanism (e.g., springs, levers) or result in a substantially different user experience; the actuator travel is lengthened (actuation point moves from 19.1mm to 29.8mm), requiring the mounting panel or driving component to provide greater mechanical clearance, potentially leading to interference or failure to achieve full travel. These fundamental parameter differences preclude its use as a direct functional replacement without first evaluating and modifying the original design.
