Here are a few important things to note before you proceed with your purchase: 1. Pay attention to the shape of the contact terminal. Ensure that it matches the shape of your original switch(TYPE B). This is important to ensure compatibility. 2. Determine whether your original machine requires a normally open (NO) or normally closed (NC) switch. The KSD-40LC 70℃ switch is available in both configurations. Although they may look identical, their functionality differs. 3. Verify the required temperature range for your machine. The KSD-40LC 70 switch has a specific temperature range, and it's crucial to choose the appropriate one for your needs.
(In normal temperature, using a multimeter in resistance mode to test the terminals, the one with no continuity is normally open, and the one with continuity is normally closed.)
