Industrial Forced Guided Relays

Industrial forced guided relays are ideal when safety is paramount. Their design makes it impossible for the normally open and normally closed contacts to be closed simultaneously. This is thanks to the use of a guide connected to the armature which is used to force the contacts open and closed. Therefore if the normally closed contact becomes welded it is impossible for the normally open contacts to close when the coil is energised. Likewise, if the normally open contact becomes welded the normally closed contacts will not close when the relay is de-energised.
