Stop Switch in Pakistan

An emergency stop switch is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner . The purpose of an emergency push button is to stop the machinery quickly when there is a risk of injury or the workflow requires stopping. Specifications: There are several important specifications for emergency stop switches. Emergency stop switches vary in terms of minimum operating or trip force, the minimum force required to initiate switching and in terms of contacts. Normally open contacts consist of a relay contact pair that is open when the coil is not energized. Conversely, normally closed contacts consist of a relay contact pair that is closed when the coil is not energized. Changeover contacts are single-pole, double-throw (SPDT) devices that are used to turn on equipment in either of two positions. For example, SPDT switches can be used to turn on a machine in one position and an audible alarm in another. Positive break contacts keep the contact points open in the activated position even in the event of a mechanical failure such as a broken spring or weld.
