Frequently Asked Questions (FAQ)
Q1: What is the typical lifespan of your DC Rotary Switches?
A: Our DC Rotary Switches are designed for long operational life, with typical lifespans exceeding 10,000 to 100,000 cycles, depending on the specific model, application, and operating conditions. We use high-quality materials and robust contact mechanisms to ensure durability.
Q2: What is the difference between pole and throw in a rotary switch?
A: Pole (P) refers to the number of independent circuits that the switch can control simultaneously. Throw (T) refers to the number of different positions each pole can connect to. For example, a 2-pole, 4-throw (2P4T) switch has two independent sets of contacts, and each set can connect to one of four different positions.
Q3: Are these switches suitable for high current DC applications?
A: Our standard DC Rotary Switches are designed for low to medium DC current applications. For higher current requirements, please consult our product specifications or contact our technical support team to discuss custom solutions or specific high-current rated models.
Q4: Can your rotary switches operate in extreme temperatures?
A: Our switches are built to operate within a defined temperature range, typically from -40°C to +85°C. However, specific operating temperature limits can vary by model. Please refer to the individual product data sheets for precise specifications.
