Selector Switches
Embedded selector switch P□RC-G□□ (Medium-Capacity Type)
▼Features
◼ These limit switches have been used for many years as operating switches in iron and steel works, chemical plants and cement manufacturing facilities, and contribute to the improvement of contact failure.
◼ These limit switches are equipped with Bestact (R25) as the built-in contact, which is hardly affected by environmental influences such as dust, gas, and humidity, and has excellent contact reliability.
◼ These switches are used in a wide range of applications, from micro-current circuits at signal level to power circuits for inductive load switching.
