Technical Terms
-General  
- Microswitch Switch with a very small contact intarval and a snap-action mechanism. Opening-and-closing mechanism covered by an actuator-equipped case.
- Possessional Contacts In general, a posssessional contact is used in contrast with semiconductor switches that has switch characteristics.. It functions as a switch by performing contact-opening and contact-closing closeing..
- Contact Form Contact forms such slider type, or contact opening form.
- Rating Value Value which guarantees switch characteristics and performance.
-Life  
- Mechanical Life Life of a switch when operated at regulated operating frequency without applying load.
- Electrical Life Life of a switch when operated at regulated operating frequency while applying regulated electrical load.
-Electrical Performance  
- Insulation Resistance Resistance measured between noncontinuous terminals, between terminals and non-charged metal parts, and between terminals and grounded parts.
- Dielectric Strength Maximum (limit) value that switch materials can resist without rupture when applying high voltage for 1 minute on a regulated position.
- Contact Resistance The electric resistance at contact parts. Commonly, it is the resistance value which includes the conductor resistance of all parts such as springs and terminals.
-Mechanical Performance  
- Vibration Proof Vibration range which a closed contact does not open more than regulated time by external vibration when swtiches are used.
- Shock Proof 1) Shock range which switches get no damage or rupture by external shocks during transporting or installation.
2) Shock range which a closed contact does not open more than regulated time by external shock when switch are used.
