What type of action does a momentary switch require?

• Automatically reset after use

• Press and hold to activate

• Press and release to activate

• Toggle between positions

What is the purpose of a guarded switch?

• To increase circuit voltage

• To prevent inadvertent operation

• To reduce power consumption

• To enhance signal strength

What does a micro switch detect?
