1. GPTCRM01 Substitution Conclusion The GPTCRM01 exhibits full compatibility with the Original Part in core electrical specifications (SPDT, 15A 125V AC, screw terminals) and mechanical life, establishing basic substitution feasibility. However, two critical technical differences exist. First, the actuator types differ: the Original Part uses a "molded lever," while the GPTCRM01 employs a "roller lever." Under identical mounting conditions, this results in different contact and wear characteristics with the driving mechanism. The roller lever typically offers superior performance in side-sliding applications. Second, the operating force characteristics are significantly different. The GPTCRM01's operating force (158gf) and release force (43gf) are substantially lower than those of the Original Part (170gf/85gf). This yields a lighter and more sensitive switching feel but may also compromise resistance to inadvertent actuation in high-vibration environments. Furthermore, the operating position (i.e., the drive point) increases significantly from 19.1mm on the Original Part to 29.8mm. This directly alters the exposed lever length and actuation trajectory after installation. In a compact original design, this could lead to mechanical interference or failure to achieve the intended actuation effect. Substitution with the GPTCRM01 is only viable if the electrical parameters are matched and the new mechanical parameters—particularly operating force and operating position—are fully accommodated and adapted within your mechanism design. Otherwise, mechanical compatibility verification is required.
