XW 22mm E-Stop Switches

IDEC XW 22mm E-Stop Switches utilize a safe break action design that forcefully opens the NC contacts and stops the machine even if they are welded. This design reverses the energy direction and uses the spring pressure to ensure that the NC contacts open if the emergency switch is damaged or the contact blocks break off due to excessive force. The IDEC XW 22mm E-Stop Switches surpass the requirements of current international standards. XW switches include up to four contacts in a compact package with a depth behind the panel about half the size of conventional E-Stop switches. Two contacts trip the power, and a third contact is used to alert a safety-monitoring relay. This means that these switches, which can be used in Level 4 safety category applications, offer an additional available contact. Either a push-turn or push-pull reset method can reset the switches.
