1. BZ-2RM22-A2 Substitution Conclusion
The feasibility of substituting BZ-2RM22-A2 for GPTCRM11 is relatively low. Key differences include a change in actuator type from roller lever to straight lever, significantly higher operating and release forces (538gf/170gf vs. 158gf/43gf), and a much smaller differential travel (0.001" vs. 0.020"). The BZ-2RM22-A2 may require greater actuation force and could be incompatible with existing mechanical systems that rely on the roller to reduce friction or provide smooth actuation. The extremely small differential travel may result in overly sensitive switching action, and its different reset characteristics could affect reliability and service life in applications requiring precise position control or frequent operation. Therefore, unless the application can accommodate these mechanical changes, direct substitution may introduce compatibility issues.
2. BZ-2RW82212-A2 Substitution Conclusion
The feasibility of substituting BZ-2RW82212-A2 for GPTCRM11 is relatively high. Differences include the addition of a DC rating (500mA DC, 125V DC), a slightly higher operating force (170gf vs. 158gf), and unspecified pretravel—though other travel parameters such as differential travel and overtravel match the original model. The BZ-2RW82212-A2 offers superior electrical performance and can support extended DC applications. Mechanically, it remains largely compatible; the shared roller lever actuator ensures similar smoothness of operation. However, the slightly higher operating force may require verification that the existing drive mechanism can reliably actuate the switch. Overall, the substitution risk is low, making it particularly suitable for AC or mixed AC/DC environments.
