FAQs
1. What is a momentary switch?
A momentary switch is a type of switch that only remains active while being pressed. It returns to its default position and state when released.
2. How do I choose the right momentary switch?
Consider factors such as the application, required voltage, contact configuration (NO or NC), and mounting type. It’s essential to assess the environment in which the switch will be used.
3. Can momentary switches be illuminated?
Yes, many momentary switches come with illumination options such as LED lighting, making them suitable for low-light applications.
4. What is the difference between normally open and normally closed momentary switches?
Normally open (NO) switches allow current to flow when pressed, while normally closed (NC) switches interrupt the current flow when pressed.
5. Where can I purchase momentary switches?
Momentary switches can be purchased from various manufacturers and suppliers online, including Langir at www.langirswitch.com, Hanshang at www.buttonswitches.com, and CDOE at www.Chinacdoe.com.
