Frequently asked questions & answers

What is the different between a push button switch for an emergency stop and a general-purpose push button switch?

A general-purpose push button switch is used for controls, e.g. to start machine operation or simply to switch modes. An emergency stop push button switch however, is mainly used as a safety measure to stop hazardous events.

What is Trigger Action?

A standard operator can be teased enough to open a normally closed contact without latching into the depressed position. Trigger action units are spring loaded so they only depress the contact block after it latches into the depressed position.
